Now that we have moved into the era of inorganic panels, how long can we expect them to last? My Panny AE700 is dying a slow painful death with it's old school orgnaic panels after ~2500-3000 hours.

Reportedly the new panels fix the blue polarizer issue, but do we really know? Before I pull the trigger for another LCD, I'd like to know it has some possibility of lasting more than one bulb change! 5000 hours? 10000?

What about drop in contrast as reported with Sony LCOS? Are LCD's immune from this problem?

Does anyone really know?

What about drop in contrast as reported with Sony LCOS?

May I humbly submit, this was a report from one person, and although cine4home is highly regarded, there have been no such reports from other AVS SXRD projector owners or on any forums discussing SXRD I could find.

So, it's probably better to say, what about the couple of SXRD projectors observed by Ekki, which seem isolated to the german market?

There have been problems with SXRD RPTV related to heat dissipation that caused panel failures, and Sony has extended the warranties on effected RPTVs.

EDIT.... BTW: I had a Sony HS51 which had trouble in it's 1st year and was repaired by Sony. I then had a Sony HS51A, which was among the 1st LCDs with some inorganic optical block parts, and that projector was problem free for nearly 3 years and I just recently sold it.

I expect my new Sony HW10 1080p SXRD projector to last much longer than I will be able to keep from upgrading. Almost 3 years with the HS51A is pretty good for me. However, unless we see something really dramatic in 4K or significant contrast progress, the HW10 may last me much longer. Yeah right! :D

I've owned three LCD projectors and feel the lifespan of them is about 2, maybe 3 bulbs. That's about 4000-6000 hours. Most people will upgrade long before they ever hit that mark and if they don't, they deserve what they get.

I Have a Sony hs-20, 4 years 12,000 hours 4 bulbs, the blue panel is going now seeing blue, top right of screen, this one is organic panels. I also heard from installers and others that 9,000/10,000 was limit on organic LCD not sure if this is true, but if so I got my money’s worth for mine..
New inorganic should last longer. If anyone thinks I'm wrong please correct me!

I just figured this out, 8 plus hours a day for the last 4 years!!!! I Guess my children, their friends, My wife, her friends, me, my friends and the rest got a lot of use out of it!!!!!! TIME for CIH upgrade!!!

LED and laser will improve the life time of LCD technology. Less IR and no UV from them light sources.

Also less ambient heat, right?

IR=Heat

There have been problems with SXRD RPTV related to heat dissipation that caused panel failuresThat's the magic word. (Actually, "words".)

Well ventilated and maintained (regularly cleaned filters) projectors in cool rooms will have totally different life spans than projectors cooped up with dusty filters in warm rooms. I think heat is what did in my Z3 finally, although I can't complain, the idea of upgrading has really grown on me. ;)

Right you are! Anyone who can't afford to throw $2700.00 at a PJ every 3 years clearly doesn't deserve one.

Right you are! Anyone who can't afford to throw $2700.00 at a PJ every 3 years clearly doesn't deserve one.I'm almost sure I'll be spending about $3,600 on the TW4000 within the next two weeks, and I'm fully expecting it to last me at least 4 or 5 years, as that price includes the 5 year warranty. (The price is still quite high because I'm buying it in Japan.)

If my organic Z3 were still working properly, I'd be blissfully unaware of what I'm missing out on and upgrade in a year or two. I expect the TW4000 to suit my needs just fine for the length of the warranty, and I think it's reasonable for people to expect inorganic panel light engines to last more than three years, especially if well taken care of.:)

Ah that it were so.
Temperature is "part" of the equation. My cellar cinema rarely rises above 23 degrees C. In fact in winters it will drop to 18 or so. My box is well maintained, yet it exhibits degradation and image retention in the blue channel.

To the O/P:
Do you use SHUTTER?

SHUTTER inserts BLACK as signal source. The problem with this is that the panel/polarizers dissipate more heat as the polarizers are clamped down. With this in mind and degradation apparent on my box I started putting up a WHITE field (Extended [hidden] OPTION menu SERVICE MODE) when the PJ was in pause. The degradation seems to have been arrested. Co-incidence? probably, but no harm.

What projector do you have?

No, I' have never used the shutter.

And again to clarify, you are seeing degredation of inorganic panels?

I'm an IDIOT (stuck in me own universe). I was thinking that it was the earlier Panasonic's and the reference was to that. Too much time in front of these (http://www.broadcaststore.com/store/model_detail.cfm?id=671165) sans proper sleep.

Disregard any thoughts I might have had because they were lacking in thought.

my apologies,

No worries Ted. All I really want to do is help ensure we talk about all the issues around these new panels. I'd LOVE to put more than 1.5 bulbs worth of time on my new LCD projector!

Oh lordy that's so scary:( I ordered a custom Da-Lite HP screen today so the die is cast and I'll be getting either an AE3000 or 6500UB -- somebody please hold my hand!
