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,
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 email me at captkaos2006@hotmail.com. 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,

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 ... |
