Lp70 flickers and color wheel chirps at the same time. It's worse with more white in the image. Colored screen shots or dark movies have limited flickering. No issues prior to hookup to computer (Infocus blue screen). Only 8 hours on unit. How do you increase refresh rate as commented in another question (if that's the fix)?
Re: Lp70 flickers and color wheel chirps at the same...
It's chirping because it's trying to keep in sync with the dmd chip. for the refresh rate, go into the menu and first reset the settings to factory default. if this doesn't clear it up, try matching the signal.

Hi, It seems color wheel problem in your tv that gets problem after some time and you hear high pitch noise along with picture flicker. Color wheel need to be replaced to solve this issue. Required color wheel is available with PartStore.com (click to view image of part and price info) and it is job of qualified tv repairman because light engine will take apart for that. Hope these info will help you. Thanks.
try resetting the settings to factory default through the menu. if there's still a problem, take the cover off. if you look from the back of the machine, inside on the bottom left, you'll see the main board attached by a large white plug. use something thin and non-metalic to push the bottom of the board towards the plug to tighten it. now do the same to the other side of the plug. this should solve it. if it doesn't, you need to replace the main board.
this is real old right
no photo off i messing up, how can we guess, what you see?
amazing....
my guess power pack shot.
i guess you cant barrow a monitor and try that?
2nd guess blind, the back light failing
or is damage if it was hit, the LCD will have damage
gently flex the frame goes nuts, bingo.
I hope this helps you but you might wanna look into some other posts too cause it goes farther then the lamps and color wheels. Basically it's a bad product and the consumer should be fixing it. But your problem seems to be the color wheel. Or just a good cleaning. We replaced the lamb in ours and still had a color problem. We're gonna do an exstensive cleaning and dusting of our unit and if it don't work. We're going straight to the manufactor. This is enough with this product! It's costly to repair and still don't have the quality picture it should. It's more then a simple fix and too costly for ppl to just fix and move on. For how old these products are this all should not be happening.
could be an intermittant connection on the picture tube curcuit board,or a bad picture tube, a bad flyback xformer,or a bad b+ capacitor off the flyback that controls the driver transistors on the crt board. Good Luck
With P, A, S, M, mode, (set using the exposure mode dial) the following four modes can be selected to suite the image.
