My Sony Grand WEGA KFE50A10 50 in. LCD projection TV has a yellow hue over the picture except for the centre where there is a clear circle of perfect picture. I have replaced the lamp but this has made no difference. Is this the 'light engine'?

Have a yellow spot on right corner of picture on wega lcd

You have a serious problem. The optical block is bad. I have a tip at http://www.fixya.com/support/r7851924-sony_projector_yellow_or_blue_dots which explains the problem and what the solution would be.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

Hi,
I'm afraid, it is problem of optical block unit (light engine) that produce picture by 3 lcds inbuilt, the blue lcd and its related uv filters become defective and causing this kind of blue hue on screen.
Complete optical unit block (light engine) will be replaced by qualified tech to get tv fixed, light engine is costly part so ask an estimate before sending tv in.
Thanks.

describe the yellow or green hue, is it eaven all over the screen or does it look like it is more noticeable on some portions of the screen. could be that you might need the light engine repair.

hello if you go into menu in picture adjustments half way down there should be a reset option this should make the picture brighter

i have 6 grey perfect circles on screen of sony 52 inch kdlw3000

This is a problem with the light engine, try contacting sony 800-222-7669 because there are some models that they extended the warranty on the light engine :)

Greenish yellow spot only means one thing. You have a defective lite engine. The only fix is to replace the engine. This part is very
expensive. Average cost $835.00 Part number A-1606-008-A

Any speakers too close to set?

Many Sony LCD projection TV's have a problem with optic block failures and your description is exactly what happens. Picture starts turning yellow or green and blotches of yellow or green. Many Sony model have an extended manufacture warranty on these optic blocks and if you get me the model and serial # of your unit I can provide more info.
