ATTENTION: MAGENTA (or any colored) STRIPE DEFECT ON THEIR JVC PROJECTOR - Page 3

post #61 of 188
All manufacturers have problems, Sony, JVC, Panasonic, Mitsubishi, BenQ, Optoma, Sharp and Epson. Think that is about all that I've owned

Since I favored both Sony and JVC, I would still go back to JVC for their new chassis. Somehow, no matter how smooth Sony's DI is, I do notice it in action. Granted, if you're not into dark movies or sci-fi, it won't matter. I'm not a gamer but do watch fair amount of sports. Still, I can deal with JVC's motion handling.

Once again, I'm talking myself back to a JVC in the near future.

BTW, I never kept my JVC or Sony long enough to have issues. The only one gave me problem was the Mitsubishi hc3800.

Hey, if you don't keep a projector that long, you shouldn't have a problem with either JVC or Sony.

Good Luck!tongue.gif

Nobody throws them out when they are done so some poor shlub buys what could be a couple thousand dollar paperweight. It is a lose/lose. Enough people get wind of this then we end up not being able to sell them...

If I have any trouble with my X75 and I am out of the projector market most likely.

Let's not get carried away. As bad as the problem might be to someone that paid 6 or 7 thousand dollars for a projector, for someone getting it cheap, it's STILL A BARGAIN. The line doesn't render the projector unusable.

So far, I think I should feel lucky..... In a sense. I don't have all the details requested, but here is the summary.

Two months or so before my RS20 warranty expired, the line appeared. Not wanting to take a risk, I sent it in right away. The optical block was replaced. I'm now more than 1000 hours into the new one, and so far so good. Will it last for ever? I don't know.

But to buy more time, or at least as a placebo, I'm running it in high altitude mode, and cleaning the air filter quite often. My hope is that it lasts long enough for a good 4k projector to be affordable.

Fwiw, in talking with my tech, he has seen proportionately more failures on Sony projectors. Slim comfort, I know.

I wonder what the lifespan of these high-end projectors are supposed to be!

A lot of enthusiasts on here sell them on before they ever change their first bulb (Assuming it didn't fail).

Has anyone ever clocked up 10,000 hours or more on one of these things?

I do know a couple of people with RS25s that are on about 2000 hours and no line has shown up on them yet. So it wouldn't be fair to say its inevitable. While the issue is clearly pervasive , and anyone that it happens to will be very unhappy and vocal about it, I think it is still a minority. Of course we have no real way of knowing what percentage of failures like this occur, especially as those who get it out of warranty will have to live with it rather than repair (due to cost).

I am not aware of this issue ever having shown up on the recent chassis. Of course there have been faults and failures, but not this specific issue. The trouble is these projectors are at the very edge of usability and reliability because of the extreme heat and duress these boxes are put under. Until laser projection I doubt we can ever expect to see the longevity of a modern flat panel TV!

There was a poster on here a while back warning people to stay away from Sony LCOS projectors. His projector had panel degradation after five years. The poster turned his projector on in the morning and did not turn off until the evening. He did this 7 days a week and had over 20,000 hours on his projector. Said he went through 7 lamps. I told him his warning thread was an advertisement for Sony, not against Sony. Projector was a VW60.

Interesting indeed. I think that's the highest hours clocked up I have ever come across. While I agree with what you said, I think it still points to the fact that projectors are for your special weekly movies and sports events rather than a total replacement for a TV.

The main problem with using these projectors all day (or night) long like a TV is that they are continuously moving a lot of air, which I believe will cause a problem at some point. They need to try to improve the filtering of the air that's drawn in. I wouldn't be surprised if it turns out that dirt, dust and/or heat causes the magenta stripe. wink.gif

Yes I suspect you are right. On top of that there is some kind of mutation occurring in these projector panels (any LCoS panel) . If you put a brand new bulb in a 2000 hour old projector, it still won't be the same as when it was new. You can normally calibrate out the changes to get almost all of what you had from new, but it won't be quite the same again.

When you say "panel" I think of the actual D'ILA or LCoS chip and I don't think all these problems are with the actual chip as opposed to ALL THE GLASS in the UNSEALED optical block. I tore down a Sony SXRD from an A2020 that had all those problems and think, as I've said before, a chemical reaction that changed the filtering....and I was able to correct it with alcohol and a lot of time rolleyes.gif

As for calibrating after a bulb change, there are so many factors to consider that it's hard to generalize. But, I I put about 5K hours on ONLY 2 bulbs with my old G15 with NO PROBLEM. Although they reduced the chip size (1" to .7") when they came out with the HX series, I think they were made using the same process so there shouldn't be any real difference. I'm not able to get to the "factory settings" on the RSxx like I was on all the older models up to the RS, but, there was NOTHING that couldn't be adjusted on those models. I'm glad I no longer repair projectors since the only thing I have for the RS series is that ISF applet to adjust the color. You would have thought they would have supplied that with the projector.eek.gif

I have no doubt that the filters go through some kind of chemical reaction and that plays a part in the change. But certainly for JVCs what you see is a permanent shift in gamma response at certain IRE levels. 100% remains the same. 0% remains the same. But what tends to happen is that particularly 50-90% IREs start shifting to 100%. You can calibrate that out, but a new bulb doesn't get you back to the initial response. "Something" seems to change inside. I would have that change was the chip itself but I could be wrong. I have never had any JVC long enough to see if it eventually stabilizes or keeps moving forever as it ages.

Since you don’t know the spectral response of the new bulb (or even the old bulb), the shift you describe might be correct or normal under the circumstances. Why are you assuming it’s a problem with the D’ILA chips? JVC must have been well aware of all this, which is why they added the CMS on the higher end models, which would correct what you're referring to.smile.gif

Now the magenta stripe....THAT'S A PROBLEM....whatever the cause is.wink.gif
post #74 of 188
Good news, my projector is still under warranty an they are replacing the optical block. I asked if I could up grade to a newer model and was shot right down. They will not do anything but fix it, at least I might have another 2 yrs before I would have to replace it. The Repair is around $3,500 to fix it and would not let me get a newer one for the same amount, makes no sense. I know this is going to happen again and at that time the warranty will be now good. I thought JVC would do more, guess not! rolleyes.gif
post #75 of 188
Just to reiterate: The magenta + faint green stripes on my RS35 never faded at all with heat or prolonged use.

Sent it for repair. Even though it was past warranty, the issue had begun just before warranty ended, and JVC honored it. Covered shipping too. Would've been ~$3,700.

For those of you who got the problem post-warranty, if you purchased with an AMEX (and perhaps other cards) remember that you get another year of extended warranty with them so you're not out of luck yet.

You've got a GOOD point about what credit card a projector was purchased with. In my own case, I paid with an E-check because they would have wanted to charge more for a credit card. If I would have been aware of any problems at the time, I CERTAINLY would have paid the extra percentage for using a credit card.....or might not have purchased it at all.wink.gif

While WE ALL KNOW that they will tell you that the projector will need a new "optical block", I would STILL like to find out WHAT in the OB is purportedly going bad?rolleyes.gif

You were very lucky. Please let us know how it works when you get it back.smile.gif

P.S. - At this point in time I still have nothing to complain about yet since I still don't have enough hours for it to appear.

Blowback, that's why. They know in the days and ages of Forum speak and speedy info sharing, if they start replacing people's projectors with newer models, they know a certain % of people will try to take advantage of the situation. So as always, the many pay the price for the misactions or bad deeds of the few. In some extreme cases, MFR's have done this, but it's rare and only happens usually if you experience the same defect twice in a row, not sure if JVC ever does this, but I kind of doubt it since they are a more high-end MFR.

I bought it direct from AV Science, which was great -- and speedy. (Specifically, Jason Turk was very helpful.) FWIW, AMEX had confirmed they would have covered this repair if JVC hadn't.

Got it back from Mendtronix (formerly Projector Doctor) last week. Working like a charm.

Except Godfather III still largely bites. I thought maybe the repair would fix everything.
post #79 of 188
My RS25 started with the dreaded Magenta stripe about 5 weeks ago. Just 3 months after the warranty expired. 1501 hours on it. Fortunately AMEX covered it for another year and everything went very smoothly with resolving it. Must admit it was my first time utilizing the AMEX assurance program.

I actually got worse treatment the second time around. If it hadn't been for a pricey extended I would have been SOL. I got nothing but ball scratching and blank stares from JVC.

Nice to know they are still doing that. I had my AMEX card cover my first ( expensive ) Blu Ray player, which died 2 months out of the regular warranty. Got a full refund, enough to buy my current Oppo BDP 83 ( which still is working great ) !! smile.gif

What the Hell, 10,000 dollar projector with so called hand picked parts is developing the same problem I had with my SONY SXRD 70". I hardley use this thing and have had it for 2.5 years and only just over 1300h on my first bulb. What a piece of ****, I think I am just going to stick with a cheap projector for now on.

Anyways my projector was bought brand new JVC HD990 the so called flagship model.

I wonder if the new models are having the same problems.

I was also the victim of the Sony SXRD's. At least after a law suit and a lot of customer screaming, Sony offered LCD replacements for about 25% of the cost of a new ones. However, they never did publicly identify EXACLY what the problem was or what caused it and just stopped making SXRD TV's, which IMHO had about the best picture quality of any TV out there (or tied with the best Panasonic plasma).

In the case of the JVC D'ILA projector, I also bought the RS35 (HD990), which purportedly had hand picked assemblies. A lot of good it did! While I don't have the problem....yet (because of illness I just haven't had a chance to use it much), I'm sure that it WILL occur at some point. However, UNLIKE SONY, JVC still hasn't admitted that there even is a problem, let alone what might be causing it. It's certainly clear at this point that A DESIGN PROBLEM EXISTS. They should at least offer to exchange these defective turkeys for a new projector (assuming the problem doesn't still exist in the new ones, since they don't even admit there is one), for a VERY SMALL amount of money. wink.gif
post #84 of 188
I had a extended warrenty through The Brick Wearhouse and if u have to get the tv fixed for the same problem 3 times u get a replacment. I had the 60, then got the 70" never had a problem with the 80" but sold it once I got my projector. So worked out good for me.

I wonder if jvc would give me the cost of the optical block replacment towards a NEW model?

Anyways going to where I bought it on monday and see what they can do.

I just dont know what else I should get I was thinking Epson/Panasonic I know its a step down but buying the high end stuff anymore is just starting to piss me off.

I am going to call them on monday and see what they say.
post #85 of 188
Just wondering everyone that has experienced this problem, did u guys have the projector calibrated?
post #86 of 188
Well my jvc hd990 is off to get fixed. Ill keep u guys posted. I am thinking on getting the DLA-X95RB but just worried about buying another projector from jvc. I guess the guy must of been drunk when selecting the best high end parts.
post #87 of 188
Is there any way to buy a warranty with the RS20, if I bought it used 2 years ago? I figured that if I bought a warranty, the problem would not happen biggrin.gif
post #88 of 188
Well I heard back form jvc my parts are on back order and they are giving me a extra 1 year warrenty. Big ****en deal. I have a so called 12000 dollar projector with hand picked parts and only 1400h on the bulb and Its broke. I think it's time to jump ship from jvc. Hand picked parts my ass. They must pick them from a junk yard.
post #89 of 188
Has anyone seen the magenta stripe re-appear after the pj was serviced by JVC? I don't believe so, but want to make sure this is correct.

You misunderstand what "hand picked" means. They have no idea which part will fail and the selection of parts has nothing to do with longevity. The selection of parts are based on performance numbers such as contrast and convergence. Simply put they bin the various parts of the optical block and the best performers are save for the higher end SKUs.

I really see little value in JVCs top tier as the gains in contrast are so easily lost by bad environmental placement and control. Would rather get tier two and save 4 grand.
