JVC, if you are listening: I have researched every tv I can find. I like your set. However, after reading all these stories (and elsewhere), I have judged your product extremely unreliable. I would rather pay more for "inferior" technology than purchase your product, which you do not stand behind. You have lost me as a customer, perhaps, on any product you sell.

Sincerly,

Lost Customer.

Thanks to everyone on this forum for reporting your mishaps. I am sorry for you.

Hey guys!

I'm back. Been enjoying my 52Z575 since May. However, I am beginning to notice a problem. If it is a very light picture, such as a primarily white screen, I'm noticing some spots of what I'd call discoloration. You still see everything, but under these spots, stains, or whatever you want to call them, it is a little bit darker. I've tried the monster screen cleaner with no luck. I think the problem is not on the surface but something underneath. I do not notice this at all with average to darker pictures. And it seems like you can only see it from certain angles.

Any idea what this might be? Thanks!

Francis C,

There is no 1/2 pixel adjustment... in the service menu.

There "should" be a "manual", "static" adjustment that is done at the factory when the light engines are assembled since after all there are (3) chips, just like there are (3) CRTS which are converged to form the picture.

No one here... or any of the otther boards I've been to have posted any such info. (Intial set-up of the light engine chips)

Sure wish some JVC techs woud be nice enough to post some training doc's, TSB's.. tips.. but alas there seems not to be any techs here...

Francis C,

Had already found that page on the "USER"(AKA Owners manuals) for the projection units.. What I'd be really interested in obtaining are the actual training docs.

Didn't see any info in there about adjusting the chips per-se... just the standard owner manual type stuff on that page. That being said please don't hesitant to post future links, because what might not be useful to me for example might be a gold mine of info for someone else:-)

On the service tech training docs...

There has to be documention out there somewhere. I can bet you there is a set-up procedure on doing a manual adjustment of the chips, the light engine itself. My red is 1/2 off also.. So I'd be all "ears" if someone that worked for JVC, was a JVC "tech" could provide some info on the subject.

Should be a pretty simple process..

1: Display the convergance service menu, (and or a grid) centering the values (I.e putting the adjust in the "middle" of the 'electronic" adjustment.

Then tweak the chips physically to bring them in alignment. I would imagine it wouldn't take too much "movement" of the chip(s) to bring them into alignment.

The problem with "tweaking" the chips manually is they are sealed inside the light engine. You can't access them unless you tear down the entire light engine assembly. I'm not sure if too many people want to mess with a $1200 part like that.

Mr Lynch,

I know the light engine is pretty much inside the light engine assembly.

Still, once you get access, Or when the light engines are being set up at the factory there has to be a way to do the initial, static adjustment since there is VERY little adjustment via the convergence adjustment via the service menu.

I have two more questions, Just learned alot about my TV by reading past post. When I do a self-service check everthing is okay except for SYNC M:NG S:NG and TUN:NG2, anybody what does that mean? And also I read in a past post that no matter what you feed the JVC TV it will upconvert it to 1080i and then downconvert it to 720p for display. Anybody is that true? And if so would it be best just to set my stuff to 1080i thru HDMI and let the tv downcovert or have it set to 720p? Thanks

Hi all,

I just bought a 56G886 and I have some questions, sorry if they are repeated elsewhere.

1. What is the expected life of the lamp? I'm a little spooked by the folks that buy 2 and 3 lamps a year at $200-300 a pop.

2. My TV changes channels absurdly slowly. Im talking 3-4 seconds per channel--surfing is hell. I checked and the floor model at the store does this too. Is there a way to speed this up? I'm using analog cable tv (digital to be ordered soon). I spectulate that its a A/D conversion delay and maybe it will get better with digital cable?

Thanks in advance

Ken

I would highly recommend Brian at Tapeworks Texas for a TV purchase. I contacted him after seeing his information on this forum. He personally ownes a JVC HD-ILA. He spent atleast 10 minutes on the phone discussing his experiences and information on TV antennas. I ordered a JVC HD61Z786 on Monday night and the TV arrived Friday. The set was shipped from JVC in the Chicago area. The delivery person helped me bring it into my living room, I unboxed it to confirm no damage and then signed off on the paperwork. The TV was manufactured in Oct. 2005. My credit card was charged 3 days after the TV arrived. My MACK warranty paper work arrived within a week. A week after the TV arrived, Brian phoned to make sure I was satisfied and to see if I had any questions. I did have to pay state sales tax but Illinois needs the money. This is great customer service, thanks Brian. (I do not know Brian nor do I have any interest in Tapeworks Texas Inc. although if they sold stock they might be a good investment)

HDMI green screen-

Sounds like you need to reset your HDMI port. Someone posted the instructions on how to do this not long ago.

Ken-

Channel changing speed will depend on the signal. If you have standard cable then the TV must convert the 480i signal to 720p to fit the screen. It takes a second to do this. When you get digital/HD cable set the cable box to a 720p output and turn the 4:3 override "off". This will ensure that every signal sent to your TV is a 720p signal. No conversion by the TV will be needed and the channels will change much quicker.

I plugged my VGA input to my laptop, and my TV (HD-61Z886) says "Invalid Signal", even though I've set the laptop to 1024x768 at 60hz. The laptop is a 1yr old Dell running Windows XP.

I can see a picture on the screen, but the colors are off, and the screen is messed up, with the Start Menu bar about 2/3 down on the screen and the top part of the image repeating on the bottom.

Anyone have (or solved) this problem? Thanks for your help.

Anyone looking for a 70" JVC, be sure to read this.

We have 2 JVC 70" "G" series sets that we need to move. These are in stock and ready to go next week. I am leaving town shortly, and will not be back in the office until Tuesday morning.

Here's the scoop on the 2 sets.

HD70G886 #1 - $2300.00 - this set was a demo unit. Unsure of the lamp hours, but unit will still hold FULL 1-year JVC Manuf Warranty, plus we will be able to do the 3-year MACK warranty on this one for only $210 to cover you for an additional 3 years on the TV and for 3 years on the bulb. Set is in perfect condition. Buyer will pay shipping and any applicable taxes. If you are interested, please email me at tapeworksbrian@sbcglobal.net This is a SIGNIFICANT savings from the original price.

HD70G886 #2 - $3300 - this set is brand new, in box, never been opened. Also a significant savings over the original price tag. FULL 1-year JVC Manuf Warranty, plus we will be able to do the 3-year MACK warranty on this one for $310 to cover you for an additional 3 years on the TV and for 3 years on the bulb.

Trying to move these before the end of the year to ge them off the books for the year. If you have any questions, please let me know. I will be out of town, leaving this afternoon, and returning this weekend, so I will not be able to respond to emails for a couple days, but rest assured I will get back with you.

Thanks,

Another problem I have is when I change from normal TV stations to HD channels when the screen changes to HD format it makes a cracking noise via the TV speakers. It only happens if I use the speakers on the TV. This is my second tv because the sound went on the first TV. All this since last Sunday. Man am I frustrated. I'm so worried this cracking noise is going to kill the sound again.

RE: JVC service SUCKS

Baldo Lazarini,

Service sucks accross the board. It's not just a JVC thing. Having CS reps who don't know that the HDMI port does video and audio is not uncommon...

You might try going into the service menu to see if there are any error codes, and maybe try reseting the HDMI port.

Me thinks alot of these problems people are having with HDMI is because the "Hollywood" types are more concerned with making sure the HDCP anti-copying part of the data stream is working at 110%, instead of making sure the audio, and video are working at 110%.

HDMI at this point is like Windows version 1.0... sort of "buggy".... May have problems with the video/audio....But that HDCP works good!

Baldo,

Search just above. The entire process is listed. It is VERY easy to accomplish. However, the sound issue may be related to some early versions of the HDMI board that did not produce sound. I had that fixed on my TV (original Z) by having them replace the HDMI board.

You say that your TV is making crackling sounds when you switch normal TV to HD stations. What are you hooked up to? And, you have that through HDMI. Are you sure it isn't the component (i.e. cable or satellite box I'm assuming) that is causing the crackling? Why are you hooked up through HDMI instead of component video?

P. S. Don't condemn JVC. My dealings with their technical staff have been excellent. You just need to drill down to the right people. I now deal with them strictly via email.

Well.....I seen the video via component and HDMI is way better. The cracking sound is only when I'm connected to the cable box sound. In the home theatre it does not crack when you change to a different channel format. I looked at the posts earlier and they lead to other posts with urls to other posts. I still cant find the proceduure to get into the service menu.

Baldo,

It is a simple search. Since you can't do that, here it is....

Your fix worked great! I was showing the GSOD (green screen of death) on my JVC HD-56G786 and immediately blamed my LG upconverting DVD player (it's cheap!). I then did a search for "JVC GREEN HDMI" and found this page as #1 on google. So, just to recap, and get this all in one post - to get this fixed, you must do the following:

1) Turn on TV
2) Make sure the remote toggle switches are set to "TV" and "VCR" respectively
3) Press the "Sleep" button
4) Simultaneously press "Display" and "Video Status"
5) Press "2" (Self Check)
6) Turn off the TV
7) Wait for fan to turn off (30 seconds or so)
8) Unplug TV
9) Wait for 30 seconds
10) Turn TV back on

Okay I am getting the GSOD (green screen of death) while trying to get my new Sony NS70H DVD player to work with HDMI with my HD52Z575.

Well I tried the the procedures to fix the GSOD i.e.
1) Turn on TV
2) Make sure the remote toggle switches are set to "TV" and "VCR" respectively
3) Press the "Sleep" button
4) Simultaneously press "Display" and "Video Status"
... etc ...

and this did get rid of the GSOD but now I get the black screen of death. No picture with a black backgroud.

But if I unplug the HDMI cable and plug in I get a picture.

Is there anything I can do just to get the DVD player to output via HDMI to the digital input on my JVC?

Here's my question: Would I get a better picture with the receiver set to native mode which would allow the JVC to make any necessary conversion, or setting the receiver to output 720P which should make the H20 do the conversion?

Anyone know the answer or have an opinion? Tks

Hope somebody can help. I turned on my TV this morning and the screen was reddish as if no blue signal was coming in, it was like this with all the inputs. I shut off TV for a few minutes and it was fine. I then did a self check and it came upo with several errors. So I reset the failure memory and now no errors show. My question is should I be worried? Is this a potential problem down the road or should I just enjoy the TV?

Also I just hooked up a new toshiba PScan DVD player, might that have something to do with it/

JVC Service is criminal and their TVs are garbage; a winning combination. I bought a 52" HD-ILA set (52Z585 - Bernie's version of the 575) from Bernie's on 9/20/04. It was serviced 9/25/04, 3/28/05 (we were away that fall), 5/2/05, and 8/19/05 (we were away for 5 weeks of the summer) - the last 3 times for a blown-out lamp, with multiple day delays before service arrived. I got them to take the set back and replace it with a new unit, an HD52G886, The new unit was installed 8/22/05. The bulb dimmed on 9/30/05, and blew on 10/11/05. JVC said the bulbs were back ordered. It took until 10/15/05 to get a replacement (I asked for a manager and insisted on overnight delivery). The bulb blew again on 12/24/05. When I called JVC on Monday 12/26 (no service over the holiday), I was told their "computers were down - call back in an hour." I did; still down. Called 12/27; still down. Called 12/28; on hold 15 minutes, dropped off line. Called again. On hold 21 minutes. Told that they would send the bulb UPS 2 day, but that the "girl who handles this is not in this department - but I'll e-mail her". Asked for her e-mail. Refused. Asked for her direct number; refused to give it to me. Asked for a manager; refused to connect me. I asked when to expect the bulb; answer: "if they are back ordered, 1 to 2 weeks; otherwise, maybe by the weekend". These people have a bush league product that blows $200 lamps every 2 months, an unresponsive and dysfunctional customer service operation, rude customer service reps, and no inventory of frequently-failing parts. I am contacting the vendor where I bought the set and returning it. If there is a class action suit for fraud against these jokers, I'm in. This is fraud. They say their bulbs last a year and a half and they last 2 months, with extended waits for replacements - and they know it, and still lie about their longevity and continue to sell defective product. This post will be forwarded to our Attorney General's office and to everyone I can think of that can harm these crooks. JVC belongs out of the TV business.
My machine is on an APC UPS
Serial number 12063472AA
Amount of run time on set /lamp (or "lamps") 2 months, ~4 hrs/day.
How set is used each day. Watch TV for 2 to 6 hours or so, depending on day.

$3500 for a TV set that works for 2 months and then is out of commission for a week to 10 days. 2 different TVs, both with the same problem. Absolutely criminal.

What a fing joke. I am soooooooo pissed right now. Took back my first hd52G866 that i bought last Sunday the 19th because the sound went on it. The store I bought it from replaced it with this brand new one I got on thursday the 22nd. On Saturday while changing channels the screen went black and i couldnt turn the TV back on. After unplugging for an hour it came back till tonight. While changing channels again it went black and i cant get it back on. Its been unplugged for 3 hours now and nothing.
