I am in the market again for a new projector and noticed the Epson 5030 at Magnolia and liked what I saw. However I remember having LCD optic block and blue polarizer issues on my old Sanyo projector and whites that turned piss color after a few years. My Sony VW40 has been a solid champ the past 5 years, I have the slightest degradation that started on it's 5th year(blue tinge on extreme bottom left corner) which right now is hardly noticeable, and has not worsened in the past 5 months.


Basically, I am wondering if LCD has made strides in this department, I have put about 14,000 hours on my VW40 and have been really impressed with LCOS overall. I know that my LCD was from the days of Organic panels but not sure what that really means. Anyone out there with a semi newer LCD projector that has put 10k hours without any image degradation?


Thanks

Thanks, yeah I took a look...quite humorous in some posts. I'll prob stick with lcos

No flame war at all.
But still there are some good posts.

Even if the panels don't degrade, you'll still likely develop dust blobs eventually because LCD does not use a closed light path that is only possible with reflective tech (LCOS and DLP). That's enough to discourage me from ever buying LCD again.

Older LCD projectors used organic LCD panels which had a limited life. Newer home theater class LCD projectors from Epson (starting with the UB series) use inorganic LCD panels which have a much longer life (i.e., similar to Sony or JVC LCoS).

the only LCD projectors I've used past a single bulb life are the business models we use at school. still I don't think they ever get close to 10k hours because they get upgraded before that point.


not to defend lcd, but I think in the last 5-8yrs lcd projectors have improved more than dlp or lcos, meaning that even a perfectly functioning lcd from 5yrs ago is hardly even worth the price of a new bulb anyway. I know I replaced mine that I bought only about 4yrs ago, with less than 2000hrs on the bulb, simply because a new projector I could buy for about 1000bux would blow it away! these are of course the 'cheaper' ones, I don't know what's happening 10k and up.

As I noted in my earlier post, projectors using Organic LCD panels will have a relative short lifetime. I suspect this type of LCD panels/chips are still being used in some, perhaps many, business class projectors and perhaps some low-end home theater projectors. However the Epson UB series of 1080p LCD projectors (these LCD panels are also used in Panasonic 1080p home theater projectors) use Inorganic LCD panels and have a much longer lifetime.

I guess I wasn't really clear. I wasn't saying that the business models we used broke, I was saying they got upgraded before they had a chance to 'wear out'.


the same is true of the Epson I replaced. it works perfectly still, just as good as the day I bought it. but how it worked the day I bought it is terrible by today's standards. that was my point, there seems to be more incentive to upgrade a working lcd projector(over the past half decade) than a good dlp or lcos that only made incremental improvements(in the value range anyway)

Diggin up an old thread but seems to fit nicely.

My good old trusty AE2000 has gotten a dark circle in the middle of the picture. So now i am wondering, is the life span of LCD projectors simply expected to be around 8-10.000 hours?

I am on my third Bulb around 7000 hours i would guess, which imho makes it a lot more expensive than i had planned when i bought this PJ.

Next time around i will be looking at something i can expect more from, are Sony´s ok?

Sony have a good track record. Last year there was a guy on here complaining about his Sony VW60 starting to go, after only five years. The thread was interesting, because after talking back and forth, he had gone through 8 lamps and had 20,000 to 24,000 hours on his projector. He turned it on in the morning and did not turn it off until around midnight. Did this seven days a week for five years. He was trying to warn people away from Sony. I told him that people were going to read this thread and think, "maybe I should buy a Sony." Sure enough that is what happened. Never could convince the guy that he got more than his money's worth out of the projector and that I was amazed it lasted that long. Keep in mind the projector did not die. The panels were starting to discolor and degrade the image. Guy was running his projector harder than any commercial movie theater. Also other than lamps, the projector was trouble free. Now don't expect to get 20,000 hours out of any projector because that is a ridicules amount of hours. I found the thread: http://www.avsforum.com/forum/24-digital-hi-end-projectors-3-000-usd-msrp/1436366-sony-lcos-panel-degradation-5-yrs-constant-use.htmlIf we can help you with advice and or pricing, give us a call.

Ha ha, I "retired" my Sony vw60 after 20,000 hours because of the same issues in the above post (and NO, I am not the guy complaining about "only" getting 20K hours out of it). Bought an Epson 5030 as a replacement. I put a lot of hours on my PJ's (8 hours a day, every day is not unusual - it is our "TV"). Guess we will see if the inorganic panels are better or not :)
