Device level repair of the blue lcd device. Not a user repair. The blue device has or is failing. Happens about 3-4000 hours of projector life. Its called color decay. Suggest replacing with a dlp brand product.

Picture shows red


The model listed and some models just before it had a red or pink area oval in shape (can be almost any shape) that is caused by the Optical light engine (not cheap part) being damaged by the heat from the lamp, unless its under some warranty not cost effective to repair, last one I saw was over 600 wholesale just for the part.

62.in hitachi projection t.v. has yellow oval shape in center of screen dark blue color on rest of screen picture fine just color


A discolored Blob, loss of one color or blotchy pattern usually in the center of the screen. The problem is becoming all too common with Hitachi projection sets. What happens is that one of the lenses in the optical block (or light engine) starts to burn or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far-gone except to replace the light engine-at a cost that makes it not worth repair. if the damage is minimal than to reduce further damage, the air filter should be replaced. The Light engine needs to be removed in order to replace the air filter. Be sure to vote/rate me if this helped Thanks!

Sharp notevision xgnv6xu oval yellow spot


I have a similar issue with yellow pattern on the left and top right of my screen. Took it apart and found the blue lcd had damage that matched the yellow area that was projected. I thought it was the lens but it was the blue lcd .It has gone bad and no replacement. Are you interested in selling the bulb or the whole projector? I have since purchased another projector and am keeping the bad one for spare parts. Hope this helps..Ben

OVAL SPOT IN PICTURE


LCD 101, your blue device is dying in the projector. Very common problem. The blue device cant handle the heat and allowing the other colors to come thru. I suggest replacing with a dlp brand product.

Yellow middle, Blue Exterior


Hi Druaga

This is a Blue LCD Polarizer that will have to be replaced if the spot shows yellow.

You will find that this will only get worse as time goes by.
