In short my very good HD-61Z585 has developed the color uniformity problem after 5 weeks of use. :(


I REALLY hate to be the barer of such potentialy bad news for other D-ILA owners. I don't think I've seen anyone else report that their D-ILA has developed such a serious problem AFTER working flawlessly for a period of time.


I spent a lot of time researching which HDTV was best for me and ended up getting the all black HD-61Z585 for a number of reasons. I was set on getting a 52" but went with a 61" because of a great deal. Despite a June 2004 manufacture date my set had perfect geometry, no fan noise issues, chromatic aberration of only 1-2 pixels (un-noticeable from 11' watching normal TV rather than a DVE test pattern), and NO problem with color uniformity. The only true problem was an area on the upper left corner of the picture where it looked as if something (adhesive from the panels?) had oozed down and covered an area 1 inch long and up to 3 or 4 pixels down. I hadn't called JVC on this issue because I had been considering switching to a 52" display because of my viewing distance. But just this weekend I decided that the PQ on a 52" at 11' could not look any better then what I had been seeing on this 61" for the past 5 weeks. But my work schedule wouldn't allow me the time to call JVC on this one issue until later this week.


Then tonight I'm watching Lost and notice a circular area of the screen, just below and right of dead center were skin tones seem kinda of grey and reds don't look quite right. Then during 4:3 commercials I notice that the lower left looks like it might have a slight green glow. I tried to ignore it at first, blamed it on my viewing angle with light reflected from a lamp. But the longer I watched the more I noticed. Finally I turned off all the lights, paused the DVR and went back to an all black screen between commercials... :mad: The lower left corner definitely has a slight green glow to it. Moving to the right the next quarter of the screen has a slight magenta glow, most noticeable towards the top, and there just below and right of center a circular area with a slight blue glow. The right most quarter of the screen looks fine. I pop in DVE and display all white, red, green, blue color screens. With these it looks like the right-hand side of the screen is dirty.


I took some pics of the color screens and will post them if I can shrink them up enough. I couldn't get a good one of the dark screen but this post from enflux75 illustrates the problem, though worse than mine.


Anyway, one of the reasons I decided on this set was the posts I read from other members describing JVC really making an effort to resolve issues with this TV.


Now I get to find out for myself. Stay tuned...

How do you get your screen to change colors like that? I have a slight hint of green at the upper right corner when watching black scenes. I know for a fact it wasn't there when I first got the tv because I checked for it. It seems to develop over time.

I decided upon getting the D-ILA and went to buy it at a local shop. They were sold out and said that JVC had stopped their production to fix a problem, so their next shipment would be 2 weeks. I hope they are fixing this problem, it sounds about the same as the coloration problems described in the cnet review.

Holy crap,


Man Valacirca, sorry to see your problem. You know it's funny I was getting ready to start a thread about how my repair went, then I saw your post. I finally got my replacement HD-52Z575 chassis installed by Frontier Enterprizes (Paramus NJ) yesterday. The repair guys were pretty clueless (they didn't know the TV had a convergence adjustment in the service menu among other things), but changed the chassis out with the speed and precision of a NASCAR pit crew.


I'm going to give a more detailed description of everything including scrennshots and pics of the TV apart ( I snapped some pics while the repair guys went out to their truck) soon. To make a long story short, the new chassis fixed about 85% of the problem. It looks MUCH better than the old one in terms of uniformity and black levels and has no dead pixel and good geometry. BUT, there is still some green glowings stuff on the RIGHT hand side of the screen now instead of the left. Although it only takes up about 25% of the screen where the old chassis had the "green glow" on over 1/2 the screen.


You're problem is bad news, but I think we are starting to see a pattern that explains how TV's get out of the factory that way. They look perfect on the test bench at JVC then degrade either during shipping or after some short period of use. You know I could swear that when I first got my HD-52Z575 it had a uniform black screen. I will be sending detailed info and more pics to JVC.

It looks like your TV had a problem from the beginning and got worse over time. That doesn't mean other people's sets are going to go bad after 5 weeks.

These are screens from the reference section of the Digital Video Essentials DVD.

Nope. I checked for this issue about two weeks ago using the same color screens from the pictures. At that time each color was perfectly uniform across the entire display. Also I watched The Day After Tomorrow on Sunday would have certainly seen the problem in any number of the scenes with snowy landscapes. In fact I am pretty sure the color was fine during the baseball game I watched right before Lost came on.

Well I didn't have much success with JVC today. I called the customer support number and the person I talked to told me to expect a call from a product specialist within a couple of hours. That call never came.


Late in the day I got the number for the local JVC authorized service company from the local B&M I bought the TV from but it was too late for me to reach anyone.


I'll bark up that tree tomorrow.

I also had mine repaired with a new light engine. I would say mine is now at about 95% compared to what it was before the repair.


And just like enflux75 I could swear that mine was fine when I first got it.


Time will only tell if it gets bad again...

When you call JVC press 9 during their menu system and you will be connected to the "Product Support Specialsts". (not part of the normal menu)


When I called about my issue a few weeks ago they passed me along to someone else after them who was a support engineer just for this product, but you need to talk to the support specialists first.

Thanks Micah008, I gave it a try but the first time it rang and rang with no answer or voice mail. When I had a chance to try back they were closed.


I called the local JVC authorized repair company during lunch. I nice woman explained that they had not been trained on fixing these sets yet and as such were not allowed to work on them without specific approval from JVC. She took my info so they'd have it when they got the go ahead from JVC but said I need to call JVC again to get them to OK the work...sigh.


Again I call the main JVC number, I explain the situation to the first level person, again they take my info and say I'll get a call in 1-2 hours.
No one I can talk to now, I ask? No, they'll call you within 2 hours. But no one ever called me yesterday, I point out. Sorry. Two hours. :confused: Lather, rinse, repeat...


I immediately call my salesguy, explain the situation, he's going to call their JVC rep.


Call JVC, select option 9, no one home...


Two hours pass...(que chirping crickets)


Four hours pass...(que sound of wind blowing)


Call JVC, select option 9, closed...


Later I get a voice mail from my salesguy that he too is running into problems. :eek: But he promises a new TV when stock comes in if this doesn't get straightened out by then. Cool!


I haven't COMPLETELY given up on JVC's customer service but after two broken promises of a call back they seem to be working hard to lower the high expectations I had. :(

I have the 61 incher.I had the green haze/ within black sceens;almost the entire left side. JVC is slow and aggrivating--- but I also got the light engine exchange after 3weeks and many calls. I watched the guy do the simple 15 min. exchange. It was done on this past Thurs. So I guess I'll be watching and waiting. I do love the pq. Geo

Ya know... I was all set to plunk down $4k-ish on the model with built-in tuner and cable card which is supposed to be coming out in the next few weeks. Now I'm hearing that JVC stopped production to fix something (is this true?) and now I'm reading these posts from people who have weird things happening to their picture. I'm having second thoughts now. I REALLY like the picture of the one on display at my local Best Buy, but, I will probably take a very close look at the SONY 55" XS when they come out (hopefully next week).

timick1- Well, BECAUSE JVC has stopped production to fix some issues would make me feel better about getting a JVC. They are fixing their issues now rather then ignoring them and continuing production.
