Do I have burn in on my Panny 700?

    I run my projector on econo mode or whatever Panasonic calls it and it is a few hundred hours shy of the 3000 mark, at which point it will turn off until I replace the bulb.

    Since I got back I have been noticing that the overall picture seems to have a somewhat blueish tint to it, and there are distinct areas on the screen where this blue is a little darker, and seems to be permanent. The burn in 'look' does not look like any type of lettering or look like a game was left on, it is rather dull and undefined.

    Is it possible that my bulb is dying? To my knowledge most projector bulbs don't slowly die, they pop and never come back on.

    If it is burn in, what needs replacing on a Panny 700? Or should I just replace the entire projector when the funds are available. It is not bothering me all that much, namely because I can't afford it right now and have other interests as far as money spending right now, but it is slowly getting on my nerves and I'm wondering what I might be looking at to get it fixed. If it is in fact burn in.

    Anyone encountered this before with an LCD front projector?

    the panels might have gotten burned out. I believe the blue LCD panels are somewhat notorious for dying faster than the other two.

    I personally would just get a new projector (this is what I did just two months ago 700-->100x)

    Yeah, I always here something about polarizers or something on LCDs? I'm really not an expert so I'd just be google searching to provide any more info, which you can obviously do too.

    Yeah I just wanted to check if anyone here had first hand experience.

    I'll probably just replace it when I can.

    Yes now you need 1080P and some of the new 1080P LCD units are pretty cheap.

    I've got an Panny AE300 still going strong. Getting closer to 4000 hours on the original bulb. Shouldn't shut off when it hits 3000 and if it does I'm sure there is someway to let it go past this.

    There's a chance what you're seeing might be a very mild dust blob. If you pull the cover off and run some compressed air in there with a vacuum going as well, might solve the problem.

    Hmmm...Good idea and thank you.

    I have an AE700 as well. It seems to be running a similar course as yours, including having to have the power board replaced.

    Mine is at about 3500 hours. The projector will still turn on if you have had it in low power mode. Not sure what the timer is on this, I think perhaps 5000 hours before it will not turn on.

    I can say that my panels do have some type of uneven pattern wear, and it is directly at the edge of where I watch 4:3 material. So I don't see it watching normal TV, but a movie or HDTV I see the colors on the side are darker. The divide is very sharp, and I have a hard time believing it is dust or something obstructing the optical path.

    I've tried for the last 100 hours to run it in stretch mode to even the wear, but this isn't fixing anything. I have wondered if a new bulb may be bright enough to offset this, but am also worried it may be even more pronounced.

    Just moved into a new house, and after 4 projectors, thinking of going with something else. Possibly one of the new Samsung LED DLP's.
