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.

1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

White spots on screen i have changed the lamp


It's probably you have a busted DMD chip, have your technician replace that, better yet buy a new projector because replacing that chip costs almost a brand new unit.

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

SPOT IN PICTURE


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.

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.
