Please Help,
I was watching the plasma tv and heard a loud pop and my screen went black. I still have sound but no picture.
I have only had this plasma tv for 14 months, and of course no warranty.
If anyone knows how to fix this please let me know I will be very appreciative.
Thanks
Jans |

Jans,
50" Zenith plasma is very common for having a power failure issue. The problem resides in the Y-Sustain board in most cases. The Toshiba 50HP66 and Vizio P50HDM (as well as LG and HP 50" Plasmas) also have the same issue as they all use the same PDP Panel (plasma panel). The parts are manufactured by LG/Zenith Corporation. If your Zenith is the model i'm thinking of (Z50PX2D), then the board you would need is the following:
http://www.discount-merchant.com/PCB-Y-SUS-MAIN-FOR-HP-HP-PL5060N-TELEVISION-p/2 761-hp-hp-pl5060n.htm
The above site is the ONLY place that I have ever found selling this hard to find part and the price is reasonable. If they are out of stock on that exact link, just search for 6870QYC004C on their site and you might find one that is in stock.
Before making any purchases, please check the part and make sure it is what your TV needs. I am simply making recomendations and trying to point you to the right direction. |

hello, I've been given a zenith z50px2d with a similar scenario as Jans mentioned, however I didn't actually witness it (I was told when they turned it on, there was a pop and the picture went out). I plug the tv in and get no picture or sound, but have removed the back and see that there are LED's lit on some boards, and the fuses are all good. I looked at the YSUS board and didn't see anything blown....what are teh odds of fixing it by replacing that board? I don't have too many $179 bills laying around.  |

Mark,
Unfortunately the main transistor on these burns out.. It can not be sourced from the manufacturer (LG).
I bought one from tristate and it came out to be defective.. seems like someone is repairing them over there by swapping components.. I don't really trust it..
I just bought another one from D-M.com for $159.99..
http://www.discount-merchant.com/PCB-Y-SUS-MAIN-FOR-HP-HP-PL5060N-TELEVISION-p/2 761-hp-hp-pl5060n.htm
It saves you $20! From their previous price. Warranty and all. |

The TV had a loud POP, then went dead no sound or picture. When I was turn on, I heard relay click, 2 fans on back run and green ligth at 3850-0012-0150 board, flashing. At stand-by it a yellow light, and when turned on, it was steady a green ligth(no flash) on front of TV. The F3 on PCB-YSUS board 4A (192Volts) blew up, new one replaced it didn't helped. Checked all (big) power transistors all goods. Ordered new PCB-Y-SUS board, it did'nt fix. $189.00, also from TRISTATE.
Any one out there, do you have any ideas?
Ovadoggvo is your TV fixed?
Thank you so much, Jenny. |

Hi Alberto. I have a Toshiba 50HP66 and I have the same problem. Loud pop then blank screen. I still have sound. Can you explain the ribbon cable scenario to me and how I can check it? |

JRM,
I bought my Toshiba 50HP66 50" Plasma a little under 18 months ago and about four or five months ago it began to act strange. It would put a block of characters on the screen that made no sense until I would unplug it and and restart it. Then it would act normal for awhile and would just need a reset every so often. I was out of the 12 month warranty so I just put up with it.....until yesterday. I was watching the TV when out of nowhere, I heard a really loud POP....and then the screen went dark. I went ahead and bought a new Sony LCD screen and was going to sell this for parts online. I troubleshoot electronics daily so I thought I would purchase a digital copy of the service manual and check it out. After I downloaded it I noticed that this is very common with plasmas (this exact failure) and only on the LG boards. I scanned my handy dandy service manual and found out that Toshiba was using these same boards along with Zenith and some others. The difference is all the other manufacturers honor their product and replace these boards even when the warranty has expired so I called Toshiba and tried my luck. Even though I've found many postings of Toshibas failing and hundreds and hundreds of the exact same board failure...Toshiba claims to have never heard of it. I informed the "Customer Support Supervisor" of Toshiba that I would be willing to post this on a few websites and have other customers contact him to inform him of this issue. He was fine with it so here is his contact information so feel free to let him know your Toshiba plasma went POP as well.
800-631-3811 ask for Dave Thompson and let him know. |

Josh,
Thanks for the info. I spoke to Dave Thompson last week and he was adamant that they never heard of the problem and wouldn't cover it under any sort of extended warranty. Did you have any luck getting coverage? Mine was just fixed by replacing the Y-Sus board for the tidy sum of $548 (Board $395, the rest was labor) |

JRM,
that's funny. He told me the same thing last night even though he spoke to you last week. Hopefully people will read this and call him to tell them this is happening often. I took pictures of the LG boards in my TV for my own records. The pop came out of my Y-sustain board as well so I'll replace it. Did you happen to get a part number for replacement board? Thanks,
Josh |

Josh,
No, I don't have the part number because I had a repair tech do the work. Unfortunately, I had already brought the TV to him because Toshiba initially told me they would "probably" cover it but I had to bring it to an "authorized" repair center. Of course, they then declined to cover the part. I checked my records, I spoke to a supervisor named Patrick. Apparently the reason they never heard of the problem is because they don't speak to one another. |

JRM,
Thanks for all of you help.On my Y-Sustain board I've felt the two large heat sinks while powered up and one is much hotter than the other. A plasma tech told me that this was a sure sign of the board being bad.
Just to make sure that my TV is doing the exact thing your was before I just blindly order the board so bare with me. I can turn mine on and still see the text on the screen but it is EXTREMELY dark to the point that you really have to look for it. The LED indicator on the front acts like the TV is working fine but it is very dark. Did your TV do anything strange before the it went "POP"? Thanks again,
Josh |

Josh,
My symptoms were NO VIDEO at all. I couldn't even bring up a menu, not even faintly. When you turn on the TV you hear a pop, almost like a snap, you get audio but no video. Also, it's repeatable which was unusual. If I turned it off and on the pop would happen again. Strange. I checked this message board and the Fix Ya message board and most of the problems were traced back to the Y-Sus board if that makes you feel better. I also think you and whoever else is reading this need to call Dave Thompson at Toshiba (800-631-3811) and let them know what's happening and ask why there isn't a recall. Good Luck. |

Josh,
Just tried for the third time to get Dave Thompson on the phone. No luck again, but I did end up speaking to a supervisor named Nick who finally gave me the procedure for escalating the issue. You have to write a "letter of complaint" and send it to the General Manager of Customer Service as follows:
Toshiba Customer Service
Attention General Manager
PO Box 3900
Peoria, IL 61614
Include a cover letter with your name/phone number/model number/serial number.
I'm going to send mine this week. |

JRM,
Thanks for the leg work and I will write up my letter of complaint and send it out this week as well. I really hope that anyone that runs across these posts sends one in as well even if they fixed yours under warranty. Even if they did, it is still a defect that should be addressed. LG, Zenith and Vizio (all using the same boards) seem to have all done a much better job on taking care of their customers than Toshiba. It's the only way to have it addressed by the company.

I bought the 50 inch Zenith Plasma two years ago, last night the dreaded loud pop and the screen went black, but I still managed to have sound. I soon found out how many others had this problem, it was amazing. |

I also have a toshiba 50hp66 and last night when i was watching TV I heard a loud pop, twice. The screen then went very dark and I only had sound. Does anyone know if I have it fixed is it most likely to happen again? If so i may as well buy another TV! I can't beleive how many other people this has happened too. |

Well Don,I read problem after problem with the Zenith, even after it was fixed it seemed to pop again after a few months. As it has been pointed out the problem is with the Toshiba and Zenith. Google this model and you will find a host of complaints about the dreaded pop and black screen the list goes on for pages. Some that were fixed lasted for awhile, others lasted only a few months..kind of a crap shoot at this point. I think I am just going to purchase a new plasma at this point, otherwise I would be sitting waiting for the next pop and not being able to enjoy the tv. And it is a shame, this television has such a nice picture, mine was two years old, others were not that lucky. So welcome to the Pop Club. |

Don,
I ordered my new Y-Sustain board and it should be in soon. I'll let you know what happens when I install it. I already bought a Sony Bravia LCD which has an even better picture that I'm happy with. When I get the Toshiba 50hp66 running, I will probably sell it on craigslist as repaired and let someone else get a good deal on a tv and hope that it stays up for awhile.

Don,
Almost forgot, make sure you call Dave Thompson at Toshiba support at 800-631-3811 and then mail in the letter of complaint described above. They don't seem to want to acknowledge that there is an issue so one at a time, I hope we force them to be honest about it.

Hi all: The common problem here is the Y-Sustain board. It is manufactured by LG (who will not stand behind it) and sold to Toshiba, Zenith and a few others. This boards components seem to overheat and burn out (pop). The board is around $300 - $400 and my total bill for replacement by a "qualified technician" was $550. Everyone must call their manufacturers customer service and COMPLAIN ABOUT THIS COMMON PROBLEM, especially Toshiba as their service is the worst. Good luck. |

Thanks everyone for the feed back. Josh i'll defiantly call Dave Thompson and let him know about my problem. I guess i'm lucky that mine lasted for 2 years and a month! My good friend had told me that his brother owns a TV repair shop so I guess i'll take it there and see how much it will be to get it repaired. If it's less then 500.00 i'll get it done, anymore and it's a new TV for me! Does anyone know if the newer bigger plasmas (50 inch +) have the same issues? |

Thanks everyone on this board for shedding some light on Toshiba's criminal tactics. I bought a 50HP66 in January '07. At the time I bought it, I checked out numerous reviews online and this was, for the money, the best thing since sliced bread. I bought mine at Best Buy, and I declined the extended warranty. Those warranties should be a luxury and an option, not a necessity. (**Side note, at the time, I recommended the set to my parents, who also bought one at Best Buy, but they elected to take the extra coverage..more on that later**). On Monday morning, my set had some loud pops and the screen went very dark. I tried to troubleshoot but there was nothing in the manual about it, so I went online. This Y-Sustain issue can be found all over the internet. Google Zenith TVs and you'll see a lot more (it's the same Y-Sus board in Zenith, LG, & Vizio TVs). After reading for almost two hours about this, I called Toshiba, knowing full well what was wrong with my TV. I asked for Dave Thompson right off the bat, the rep told me "the name sounds familiar". After some discussion of the issue he told me that "all it takes is 2-3 people to do something like this online". What a crock. So he looked in his directory and told me the internet was spewing BS because "Dave Thompson" doesn't exist. So I asked for a supervisor. Hold for about 15 minutes before moron # 1 comes back on and tells me "the supervisor can't do anything until you have the unit checked by an authorized serviceman". I ask if I have to pay for this, and when he said yes, I declined. So on the phone comes "Patrick Williams", supervisor. He says he has absolutely never heard of this issue, and that Dave Thompson is just a supervisor who is actually lower on the food chain than he is. He tells me that he knows what DT does and what he doesn't do and that he doesn't handle claims regarding this issue. He tells me I have to take the TV to the closest facility and have it checked and that they won't help me financially in any way. He says if there were calls about this issue there would be a record of it. (On another forum I found a post from a guy who names Patrick Williams as the guy he spoke to 3 days earlier..yet, Wiiliams claims "no knowledge whatsoever" about this issue. Well I called the authorized center, they wanted me to bring the set in and look at it for a fee of 95.00. I poked and prodded the guy over the phone and got him to tell me that it is a very common issue and the fix would cost 800.00--with a 90 day guarantee (it's doomed to happen again). I called 2 other (neutral/impartial) repair centers, their response was immediate, they knew of the problem right away. I even had a FREE in house service come and look at it that day and this tech knew right away what it was. So it would seem to me that Toshiba isn't satisfied enough with ripping you off the first time, they actually want you to spend the additional loot to have the set checked out when any qualified tech can identify the very COMMON problem instantly. It isn't worth fixing, not for that kind of loot and a 90 day guarantee. A tech can put bubblegum and toothpicks in there and roll the dice that it works for 3 months, then you're out your 800 plus what you paid for the set to begin with when it happens again. Bottom line, the set is toast, and not worth fixing. **Should be interesting to see if Best Buy fixes or replaces my parents' set WHEN (not if) it happens to theirs which should be any week now**. Having no reaction from Toshiba, I called Best Buy. I got 3 year interest free credit for this and still owe them half the $$ for a useless black box. They listened to me, feigned empathy, made a case # and told me they would 'recommend' a discount when I come down to buy a new set. Needless to say, BestBuy will not have me for a customer. I asked them to act as a liaison between myself and Toshiba, seeing as their relationship is a little more established than ours. They sold a crap product (when I bought it, BestBuy was the only major distributor around that sold it, and it mysteriously vanished from their shelves a month later). Most of the (Toshiba 50HP66) complaints I read were people who bought the set at Best Buy. Why am I writing all of this? My wife is a paralegal. We are writing Best Buy and Toshiba, sending copies of the letter to the BBB, Consumer Affairs, the District Attorney and the Attorney General. It'll take time but we've had similar issues in the past that were resolved this way. If anyone, particularly those who bought their set at Best Buy, wants to share their experience in more detail, please reply below. We're eating this TV and buying a new one, but we're optimistic that justice will be done in the end. The more people that jump on board, the more damage that can be done to these crooks and you can get some restitution too.
Thank you,
Charlie in NYC |

Update
Sent letters to Attorney General, BBB, DCA, Best Buy & Toshiba. Toshiba calls me today, leaves me a voicemail asking me to call back. I call back, the idiot puts me on hold for 10 minutes and says "we researched your complaint and found that since you are outside of the warranty period, there is nothing we can do. As far as special issues are concerned, there are no special issues that have been reported with that TV". I tell him that we went over this in our prior correspondence, what is the purpose of the call and message? (also tell him that HE has 'special issues'). He asks if there is "anything else" he can help me with. I tell him he didn't help me with anything to begin with, and hang up. One down, 4 to go. |

Update number 2
This thread seems dead, oh well, I'll keep posting here, I hope someone sees this and can share any experiences or follow-ups they've had with this issue (with Toshiba especially)
So I just called AGAIN, turns out it was Dave Thompson himself who called my house. He said that there would be no monetary or warranty assistance from Toshiba. I told him there should be a recall, he said that there is no recall on this set. DUH. We're trying to MAKE YOU START ONE!! I asked him if I was the only person who called him with this problem, he said no I wasn't. He said that 'Toshiba's engineers have reviewed and researched the parts in question and found no issue'. Me: 'Then why was the set discontinued?' DT: crickets....silence... Me: 'If most average everyday repair guys who do this for a living readily acknowledge this problem, and your engineeers say there ISN'T a problem, then why not have YOUR ENGINEERS look at OUR ^$#@&* TVs?!! Maybe THEY can fix them??'
Crickets, silence, click.
Oh well....let's see what the govt agencies can do. |

Josh, my Toshiba 50HP66 just went POP about an hour ago, after 25 months! Glad to see I'm not the only one! I'll try giving this Dave Thompson a call tomorrow. Also, I'll ask BestBuy to give Toshiba some grief. Fortunately, I did buy a service plan from BestBuy, the only plan I've ever purchased. Unfortunately, I have to wait 8 days for a service apppointment, so I'm going to have to start reading more until then. I hope the service plan comes thru for me ... crossing my fingers. Between the cost of the plan, and the cost of repair though, it looks like it's only saving me 100 to 200 bucks; but it is onsite repair, so glad not to have lug that huge TV to some repair shop across town. Will update on the repairs and BestBuy Service Plan results later ... |

ok, this thread probably won't die for a while. The Pop of Death was at my house a couple weeks ago. The TV Service guy just left and said I need a new Y sus board as well. Mine was bought at HH Greg's 9/06. Football season is coming and its going to cost me a few hundred dollars! I haven't done the Toshiba Customer Service call yet. I don't look forward to it as I am pretty pissed off that I went with what I thought was a premium brand name and found out they are using all LG guts!

So the GeekSquad guy showed up ... good guy seemed to know his stuff ... after about an hour he decided to replace the YSUS, ZSUS, and YDRIVES ... without the ServicePlan total cost including labor would have been about a cool 1K ... subtracting the cost for the plan, I saved over 600 bucks and I still have 2 yrs on the plan ... the only downside is the wait time for service apppointments and parts, I figure I'll be without my TV for 3 weeks minimum ... oh well maybe I'll buy a smaller TV for the guest room ... |

My Zenith 50" Plasma gave a loud pop (4 days back)and the screen went blank. I unplugged the TV and re-plugged it to the power source. Able to get clear sound and picture ( but the picture is not in primary color, its kinda "bleached" ). LG has really good customer suport, my TV has bypassed the warrenty , but the customer rep promised me to send a Tech to my house. Tech was in today , got the boards. but he checked and found all the boards working in the TV.Tech now says that it will cost more than $ 2k to repair it. |

So the GeekSquad guy showed up with parts and fixed my TV. Without the BestBuy PSP, the parts and labor would have cost me over $1500; so subtracting out the cost for the PSP, I saved over 1100 bucks. I'm very happy with the GeekSquad service, and the BestBuy PSP. However, I can't say I'll be buying Toshiba in the future. It seemed apparent that Toshiba could have installed an internal cooling fan for 20 bucks and saved everbody a lot of cost and hassle. I've purchased a small fan to run behind by TV, so that it doesn't overheat again. The only downside to the whole affair has been the wait time for appointments and parts delivery; I was without my TV for about 4 weeks. I'll probably get a second TV for the guest room. |

same problem here, scred to find out how much labor is going to cost us or if it would be better to just buy a new TV????
How come they will not just do a recall on these tv? what about a class action law suit?? How do you find out if one has already been started? |

Thanks to Charlie T from New York (even though a Giant's fan)! He help me get Toshiba to pay for a new Y,Z, and Controller board for my 21 month old 50HP66. I had to pay the labor, but I believe the replacement Toshiba boards will fix the design problem with getting the heat out of driver devices (IPM's). Only time will tell. |

Shifler: All we did was to call them and request them, The trick here is u need to speak to the "right" rep!
It will take some time, but be persistent and you can get it done. Please be advised, do not point to the forum and "blame" the product or threaten class suite.
by the way, did you get to fax them your receipt and cover letter? |

I did call them and fax a copy of the receipt like they ask a week later they still had not faxed there part to the "mike fix it shop" we are to take it to per LG. I have called him 4 times in the last 10 days and he will not call me back at all. I have called LG and they keep telling to call this guy, to top it off LG was to send snail mail a copy of the order to fix the tv but have yet to get that.
They never ask for a cover letter. |

According to me , this is how it works.
U fax cover letter + receipt.They communicate with local LG service and schedule a visit.after that point, you communicate only to the Technician ( cell and email).
We did not have any complaint number or "fix it" letters.
be advised, you can communicate to the cust rep and request a diff technician. |

I called cust rep and told them I never got the claim paper from them and that the person they told me to use to get the TV fixed would not return my calls. They lady I spoke gave me someone else and faxed the authoriation to me and a new repair shop. I will call them tomorrow and make sure they have it to and then find out how much labor is going to cost so I can cry! |

Updated #2 I called the new repair show to see if they got the fax and the lady told me they only fix the TV if bought from them so another dead end. Call LG back and ask them what I should do now and I am told to take to the 1st shop they gave me explained that once again this guy does not return calls so he gives me another # and this place is over 1 and 1/2 away. He told me to call them and ask them if they would fix it and if they will I am to call LG back and they will fax him the repair order. To top it off when I pulled them up online they have a terrible review.
I am at my witts end with this TV and trust I will not buy another LG TV that is for sure!!! I am in the process of checking out what I can do about, class action law suit or what. |

Hi I'm not sure if this is the right thread but here goes: I have an Akai PDP5073TM which has a LG panel. I was watching TV and heard a pop sound and the display went dark. I figured it might be a power surge so I unplugged the TV, waited a while, and powered up again. Every time I power it up the screen goes a faint gray color for 1 second, it makes a pop and shuts down. Immediately the TV powers up again by itself, pops again, and shuts down. Then it doesn't do anything.
If I try to start it again it just repeats the above and stops. There is NO audio or startup blue screen at any time during this process. My TV repair guy says it is the power board, but he gave the consultation over the phone. Do I have the same problem as the previous posters with the Y sustain board? I wasn't sure since some posters seem to say they get audio. I don't get anything except 1 second of a faint gray splash on the screen. |

Charlie and Josh - Not sure if you have been able to get any resolution related to your television, but wanted to share my experience with you as well. We had your television for only 39 days when our PDP panel blew up. It was under warranty, so it was fixed, but about a year later we had three different circuit boards go. We paid to have the television this second time but we just had our third issue with the tv. It has now been broken three times in just over two years.
Below is the letter of complaint I sent to Toshiba in December 2008. I got a follow up call from David Thompson that said Toshiba could not do anything for us.
I’m writing this letter to explain my experience with Toshiba products and services over the past two and half years. I feel like I can convey my thoughts better in writing as it is difficult to try to explain the amount of frustration we have sustained through disparate customer support phone calls. We have had three serious product issues with our television within a two and half year time period, with the first happening in the first two months of purchase.
Consumers buy large screen televisions because they enjoy watching television shows and movies. Often times the sales of these types of electronics coincide with major television events, premieres etc. So please put yourself in our shoes. It’s a Thursday night, you’ve just put the three kids to bed and your favorite show that has been on hiatus for 6 months is about to start. You are sitting in front of your fifty-inch Toshiba plasma television…maybe you even popped up some popcorn. Five minutes into the program the television goes black, and it isn’t the final episode of the Sopranos. You resort to watching the remaining portion of the program on a thirteen inch television that has not given you one problem in fifteen years. On top of that you are a native from Massachusetts and your Patriots play in Super Bowl XLII in three days. You need to find somewhere else to watch the game, but you live in New York and it will most likely be with Giants fans. Please insert your own expletives here. You blame the television and not being able to watch the game at home for the Patriots blown undefeated season.
Now here is the real kicker. This is the second time the television has blown in less than a year and half.
The first breakage occurred in October 2006, when the main plasma board blew up. It sounded as though someone had lit an M80 in the house. The part to fix the television was almost as much of the television indicating that the main guts of the television had failed. At that point in time we had requested a replacement set, however we were denied by Toshiba. We were told that the television would be repaired to a condition better than new, as it would be tested with a fine toothcomb. From my perspective I felt like I just bought a refurbished television at the full price of a new television. If we wanted to take the chance with buying a refurbished product I could have saved substantial dollars on the purchase price on any number of internet websites. We should have been granted a new television, refunded money or been offered an additional warranty free of charge at that point in time. It was under warranty and fixed at no charge, but we went about a month without a TV and had to deal with removing the television from its wall mount and disconnecting all of our other components.
The second breakage occurred on January 31st, 2007 just about a year after we received the television back from the first repair. This time three circuit boards malfunctioned. In total at this point, we had had a working TV for just a little bit over a year not counting the time lost due to the first repair. We again argued our case that we had a lemon of a TV and that we wanted a replacement TV. Now we were being told that the TV was not under warranty and not their problem. At this point I really did not want to repair this television as I did not have a good feeling about its reliability. After more haggling, Toshiba agreed to pay 50% of the part cost which saved us a little money, but still costed us $500. On March 17th we notified United Radio to move forward with the repair. Toshiba had communicated to us that the parts were being expedited with an expected delivery date of March 24th. On March 26th we were informed by Toshiba that one of the required parts would not be available until June 2008 (approximately 5 months later). At one point we were even told that we may want to try to find someone who can repair broken circuit boards. So we were not even getting new replacement parts to fix the problem. We received the television earlier than June, but again we went through an extended amount of time without the television and had to remove the TV from the wall mount and disconnect all of the components.
On Halloween night, October 31st, 2008, the television was down for the count for the third time. The screen went black and the power LED light switched from green to red. It was the same issue we had seen before. My father-in-law chuckled in pity at our pathetic television. It has been just over two years since we purchased it, and less than two years of actually working television time. The television came down from the wall mount and all the components were disconnected. To save money, we personally delivered the television to United Radio for diagnosis. It turns out that the fourth circuit panel had malfunctioned and would cost us another $500 dollars for repair. It would have been nice to know that there were a total of four boards when they repaired the three boards during the second repair. At this point I refuse to put another penny into fixing this faulty product. I have not decided what I am going to do with the television yet, but I’m thinking about a you-tube video, a plasma TV and a sledgehammer.
So that is our story up until now. As you can guess I am very frustrated and have not nice things to say about the Toshiba brand. From my perspective the Toshiba plasma television that we bought can either be considered a “lemon”, and represents a small percentage of the overall product that has issues, or the product design or product parts were faulty. One would think that if we did purchase a “lemon” then Toshiba would take steps to remedy the situation. Since that has not occurred, that leaves only one other option. The plasma television product is shoddy and Toshiba stopped producing it. And not only does that lead us to believe that the plasma television is shoddy, but also the entire Toshiba brand. My five year old and three year old daughters have branded the television “hunk of junk”.
In our frustrating ordeal we went searching for the Toshiba code of conduct and company vision statement. All I can say is that if your products and services met those goals we would not be in the situation we find ourselves in. There is no point in having a vision and mission statement that only talks about quality products and upholding customer satisfaction when there is nothing to back it up. I would like to be able to say to people that, yes, we did have issues with our TV, but Toshiba really went above and beyond to make things right. It’s funny, but when I tell people about our experience I feel a sense of guilt that in someway I am partially responsible, because we didn’t do our research and chose the wrong brand of television.
Thank you for your time. |

Can anyone post pictures of the "popped" component on the "ysus" board? I have a 50hp66 Toshiba and I'm gonna try to fix this sucker, but I'm just curious if there's any way to replace the defective component on the board right off the bat or to add a fan/larger heatsink to keep this jalopee runnin loger! Thanks! This is a great forum and this info is invaluable. I hope if anyone gets wind of a recall they post! |

I spoke with Dave Thompson today, and guess what, he says that he has only spoke with one person complaining about the 50HP66 as of today. Honesty is also not a strongpoint at Toshiba Corporation.
Our 50HP66 "popped" this week, and after talking to Toshiba, we actually thought that they might help. We were WRONG. I am now going to respond through desporate channels to at least get Toshiba to pay for the new "y sustain" card and other faulty parts....I will keep this forum up to speed with the progress |

TOSHIBA 50HP66
VIZIO P50HDM
VIZIO P50HDTV10A
ZENITH Z50PX2D
... The Y-SUS is the problem in 60% of the cases. The X-SUS (AKA Z_SUS) is the problem in 30% of the cases and can be found here:
http://www.discount-merchant.com/We-provide-factory-original-parts-worldwide-p/v izio-sku9502.htm
THe other 10% is caused by a short in the lower buffer boards that may cause a chain reaction and blow the Y-SUS.
The loud "pop" that everyone is hearing is due to a failure of a "transistor" module on the Y-SUS. Again, this is not a standard transistor that can be replaced easily as it is a "MODULE" which is exclusively used on high voltage boards used in plasma TV's. In many cases it damages other components on the board. I have tried sourching the module with no luck. For $150-$175 i wouldn't mess with it.
When there is no "pop" noise, the X-SUS may be at fault... But again, you need to test for proper voltage using a multimeter to see which board is at fault. The above is just a rule of thumb. If you mis-diagnose the TV and place a new Y-SUS or X-SUS while there is a short in the Buffer boards, you will immediately "blow" the X and/or Y sustain boards.
Prices on these boards seem to be very reasonable from the above website and I know them to be a reliable source for quality products. Our service center uses them for all of our DLP and Projector lamps... as well as Plasma/LCD boards and DLP Light engines. |

I just had my Toshiba 50HP66 go down this morning. Same issue as John Carlisle above: the set powers up on its own and shows a grey screen for about 3 seconds. The screen then discharges and goes black, accompanied by a crackly "boing" sound from the back of the set (think old Atari games + TV discharge crackle). The cycle then repeats on its own. Is this the Y-sustain board, or one of the other boards? |

Wow. I looked this site up a year ago when ours did the same thing. I wish I had known this board was still active. We have the same problem, but it happened just out of warranty, and just as CompUSA was closing, so we couldn't go back and get a copy of our receipt. We had the pop, then the washed out colors, then nothing but sound. Ova, how does one test to see what board it is? What are the proper voltages? It's my parents TV, and now it's just hanging there sadly on their living room wall because my dad refuses to take it down. We don't have a lot money right now, but I think I could probably swing $200 if it meant fixing their TV. |

I have a Zenith 50" z50px2d
I just ordered a new ysus board and it still does not come up properly. It seems I may have jumped the gone. here is a pic of what it looks like. http://www.autotrix.net/ebay_images/z50px2d.jpg
Sorry the picture is not that great. I have brightness set at 100% and if you look towards the right you will see the menu is missing parts. Everything that comes up on the screen fades in pixilated and real faint.
Any help would be greatly appreciated.
After closer inspection of the X-SUS I found a capacitor leaking acid but after removing it I find nothing that looks blown... Where can I find info on voltages to test? |

Well I gave up on fixing it and decided to call Zenith/Now fully LG
I purchased my TV 12/3/2005. Its Y sustain died 09/07 and I paid a repair shop $936.21 to fix it. Now its dead again.
LG had me fax in my original receipt and they have said they will pay for all the parts. I plan on calling back after I know what the labor is and trying to get them to cover it, I've already paid for parts once which by them offering to cover now is an admittance that they should have paid for it the first time.
The least they can do now is pickup the whole repair..
Hopefully this thread will help others. |

I have a Sony FWD-50PX2 and it had the same problem, a loud pop then no picture/sound. I was lucky that it was still under warranty. I had the set for about 18 months before it went out. I only had to wait a couple weeks to have it fixed. Unfortunatly, it only worked for another 18 months and the warranty is long gone. This time, the problem is with something else. The set works for about 10 minutes then turns off. I can press the power and watch the TV for a couple more minute before it turns back off. I took it apart and noticed that the fans do not turn on. I am going to guess that the problem is that the system is over-heating and the set is going into protect mode. I've been searching for some help with this current issue but still no luck.
I did not purchase the TV from Best Buy. It wasn't from the lack of trying. I went to a few Best Buys and I was completely ignored. I couldn't get anyone to help me with my purchase.
Maybe I'll just go back to an old tube set. |

I have a Zenith 50 inch plasma. Purchased 11/05 last night I had the loud pop and no picture. Started reading on the net and discovered this is VERY common. Called Zenith and was told it was out of warranty. When i explained what I had learned, I was told to call back Monday and talk to a supervisor. It looks to me if this is that common there needs to be a recall. If there ever is one I want to know about it. After reading this message board I now know what companies to NOT purchase from. |

Back again to add to the thread.... I wrote a letter to the Attorney General of each state that Toshiba works out of, and all received a form letter from Barbara A. Hayes, manager-legal administration of Toshiba. Quote "It is TACP's position that since Mr. Parker did not contact TACP's Customer Support until January, 2009, he is past the warranty period, and thus we are unable to make an exception and give him assistance."
I still do not think that Toshiba, Zenith, and LG are willing to admit that this item, Y-sus, is or should be a recall, and not a part of their warranty program. Shame on all of these corporations for screwing their consumers. |

We bought a zenith 50" in 12/2005. We heard the "pop" a few weeks ago (7/2009) and the screen went black, but sound was still there. We ordered the y-sustain board from dm.com. My husband just installed it. The picture is back and it looks great! Hope it lasts.... Thanks for this message board! |

We purchased Zenith Z50PX2D on 1/15/06. Happy with the picture until July 2007 when with a pop the picture was gone. Called...wrote... faxed LG (they are now in charge of that product) finally agreed to cover repairs (first claimed only on year warranty I insisted on a LG website that showed 2 yrs, it was removed but I had the screen shot to prove it) It got fixed and we were happy until July 2009. Again the pop and no picture.. paid $680 fixed? 3 wks later thin multi color lines.. repair guy isnt calling back??? |

I don't have any snap, crackle or pop, but only half a screen.
http://community.webshots.com/album/573747225LpUvMK
Can anyone tell me how to remove the lower Y driver board (HT50067H005593)? I think that may be my only problem, but I can't get it loose despite having removed all of the screws. I have zero electronics experience, but I'm kinda bright and highly motivated to fix this puppy.
Is this the proper replacement part for the lower Y driver board (buffer)?

You can check the voltage through the X and Y sustain boards to see which is damaged.
Voltage travels the following direction on these TVs:
Power Supply:
http://www.discount-merchant.com/We-provide-factory-original-parts-worldwide-p/1 075235-zenith.htm
Then through Y-SUSTAIN:
http://www.discount-merchant.com/Y-SUSTAIN-PN-6870QYC004A-6870QYC004B-6870QYC004 C-p/vizio-sku9501.htm
By the way.. This is the MOST POPULAR failing part on these TV's... Above link has it for $154.99 and the quality and shipping time is outstanding. Be careful buying from a used dealer or someone not as big as Discount-Merchant is on parts. You may get a part that lasts 1/2 the time. These boards are like DLP TV lamps, they have a limited lifetime and if you buy from the wrong place, you will have to replace it more often and it can damage other components when it pops!
Next Power travels through X-SUSTAIN:
http://www.discount-merchant.com/Vizio-SKU9502-p/vizio-sku9502-psp.htm
Again.. only $154.99 and this is the 2nd most common failing part on these TV's..
......
To test which board is bad you need a multimeter... then test for the following:
1. disconnect the power board from the y-sustain board.. Check input into power board (is voltage coming in from the wall?) Next, test for voltage going out of the power supply.
2. Next test voltage going to the Y-SUSTAIN BOARD by having everything connected except the link between YSUS and XSUS. Check for voltage going into YSUS (if power supply is putting out, then ysus shoudl be receiving).. Next, test for high voltage comming out of the YSUS... keep in mind, xsus is disconnected.
If you get power comming out of the YSUS, this means your YSUS is GOOD and your XSUS is BAD....
If you get no power comming out of the YSUS this means that the YSUS is BAD.. in this case you need to replace your YSUS, however, you XSUS can also fail when your YSUS blows out.
In order to test your XSUS, you can use a multimeter to test breaking in the transistor module that has the big Black or Silver heatsink on it. You can test it by using a multimeter and applying it to the bottom pins of the board.
Again, Discount-Merchant.com seems to have many of these boards in stock and they are my lifesaver! The price is VERY LOW compared to anyone else, and the quality is outstanding. 1 year buying these boards from them without a single returned customer.
I bought one off of some jimmy guy on ebay and it blew in 1 month. I though i was saving myself money but the customer was back and very upset. Be careful! |

Thanks for your lengthy and insightful post, ovadoggvo. I still wonder whether a SUS board is at fault.
I cleaned the TV's innards with a brush designed for photo negatives and an hovering vacuum. Since that time (9 days), we're fully functional.
Will post again if something new develops. Still would like to know if the just bottom Y board can be removed and replaced. |

Hiya guys.
My wife is an Insurance Adjuster and she brought home one of these 50" zeniths the other day. The insured said lightning was the cause of their TV failure. A little searching brought me here.
When I first turned on the TV I entered the menu. It was very slow to come up. Like a reverse "fade to black". Hooked up my laptop to it and found the picture washed out and had the "fade to black" issue. I played around with it a little while and then turned it off. Yesterday i brought my meter and scope home from work . When i turned on the TV I heard the loud pop and the screen was black. I did faintly see the "no input" box fading in and out. Am I correct in thinking that the POP was a symtom of another faiure or will the screen show signs of the problem before the pop if the issue is in the Y-board. I'd like to fix it and add an additional cooling fan or some FETS to the failing cap. I did read the post regarding the buffer board problem and will be running voltage tests when I get home tonight (thanks for that Ovadoggvo ) . Is there anything else i should keep an eye out for?
thnaks Guys. I'll post me results this weekend.
BFN

F.Y.I.
"Live chat" with Discount-Merchant.com proves useless:
ME: We've diagnosed our intermittently half-blank Toshiba 50HP66 TV (bottom half occasionally goes black) as a failing bottom Y buffer board (HT50067H005593). Which of the the following products [from your website] would be the correct replacement part?
• 6871QRH080A PCB - BUFFER LOGIC RIGHT - BOTTOM FOR TOSHIBA 50HP66 TV - 6870QSC008A
• 6871QLH070A PCB - BUFFER LOGIC LEFT - BOTTOM FOR TOSHIBA 50HP66 TV - 6870QMC007A
• 6871QXH035A PCB - BUFFER LOGIC RIGHT - BOTTOM FOR TOSHIBA 50HP66 TV - 6870QWC007A
• EAX37107601 PCB - BUFFER SCAN BOTTOM FOR TOSHIBA 50HP66 TV - EBR38447602
• 6870QDC005A PCB - BUFFER SCAN BOTTOM FOR TOSHIBA 50HP66 TV
THEM: Hi Joy, either one of those parts will work ok, this is because they are the same parts. The only thing is that we list them in serials instead of quantity.
ME: So all five of the products I listed are the same thing?
A "scan" and "logic" board are the very same thing?
If so, what's with the "Logic Left" and "Logic Right"?
There is no "scan left" or "scan right."
[Time passes]
ME: Hello? Are you still there?
THEM: Sorry sir, just a second.
[I don't bother pointing out I'm not a sir.]
THEM: I see, sorry sir. I didn't pay attention to the right and left.
The thing is that we wouldn't be able to determine which board is the right one.
You'll need to consult a tech ...
And then he refers me to NESDA, which is basically a directory for TV repair service.

It's been 15 days since I vacuumed inside the TV. For the first couple minutes the bottom of the screen is unreliable, but once the unit warms up, it has worked unfailingly for hours. |

My Zenith Z50PX2D unit is apart after suffering the same "pop" then drop the picture problem. We do have sound though! After beginning to diagnose per ovadoggvo email of 2/2/09, the power supply unit kicks out 209 volts at pin Vs, where it is supposed to be 194 volts as per the sticker on the back. So maybe that is why the unit "popped"? Too much voltage. My question is , do I adjust the voltage settings to 194 and then try the TV again, or would the Y sustain automatically die? It was only turned on one time when the pop occured. Thanks for any help offered. |

I am new to this board of course.
I have a Zenith Z50PX2D. I have read thorught the post and tried to troubleshoot this thing. My wife and kids heard a loud pop and the screen went black with a red shadow and some image viewable in red. After reading the posts I checked the YSUS and had power at the upper white connector that goes to the xsus of 190 and 60v at all the pins as well as all the fuses were good. Bassed on this and your comments it would appear my problem would be the z sus or 10% chance the lower boards. I have the Zsus ou t now. I thought sure I'd see evidence of this pop. The board looks perfect. I have visually looked for evidence of this pop all over with no luck. I can't see how it would be the common ysus but maybe I am missing something.
Is there anything I can test on the zsus to see ( I have a voltmeter-well many of them). I am not real familiar with boards or how to take measurements on them but I am sure the y fuses were good and we had output voltage on every pin with a V.
Are the transistor modules those copper spiral wires with the heat shrink 3 on the zsus. They have continuity. Witht he volume of the pop one would think you could see a swolen capacitor or if this is the copper coils are at fault them blown apart.
Thanks for any help you can provide.... |

We replaced our y-sustain board in july 2009 and the picture was great but we could never get the remote control to work properly after that. Just recently, it got to the point where we cannot get the channels to stop changing and we cannot control the tv, even from the buttons on the set. We have decided to purchase another tv. :-( |

Well my toshiba just did the pop and I brought to a repair shop they quoted $800.00 to repair it z sustain board gone. so I picked it up paid $74. dollars to the tech they offered to keep it and I would owe nothing yea right. I think Toshiba needs the class action law suit just to give them a wake up call. Never buy there crap again |

I smashed mine into pieces and recycled it. It would cost $400 to replace the boards and pray it worked only to have what go wrong next? A new LCD is about $700. I bought a projector and it works great even in light. I should have done this to begin with. It is an Optoma EP 1691. 120 inch screen equals at least 4 50 incl plasmas in area. It's like being at the movie theater. The wife was skeptical but now wouldnt go back to a regualr TV. |
