I recommend you talk to Sony directly and they may offer you an exchange with latest model with a great great discount. Mine is on the way for delivery with the same 'blue screen" problem. Dont bother looking for part replacement which will cost more than a brand new replacement from Sony. Good luck.

We have a Sony WEGA 52 inch. Its around 5 years


Depending on the model number even if the set is now out of warranty--you may have some recourse with Sony. It sounds like you have a LCD rear projection---the pattern in the middle of the screen and a blue discoloration suggest a BAD OPTICAL LIGHT ENGINE! It is a very expensive part and labor intensive to replace--Contact Sony with your model number---they were offering free replacement including labor on a lot of these sets well past the warranty period.

I am from your description almost certain it is a bad optical engine.

I know I am not giving you good news but this is common on these sets--the engine has a series of lens and the heat from the lamp causes them to be damaged inside.

I do this here for free so if this has helped you at all take a minute and give me a vote here.

YELLOW AND BLUE SQUIGGLY LINES ON THE RIGHT SIDE OF THE SCREEN


Hi Fkanode.
The failure(s) in your TV is related to a part called light engine or optical block and Sony TVs are known for these kind of failures with the video showing with different colors or lines.
Check the link provide for more info or if you would like to try fixing the TV yourself.
Let me know if you would need further assistance.

Horizontal (dashed) line across screen


On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck

Yellow spots


I have no suggestions but I am having the exact problem, yellow haze in the top right corner of the screen with a yellow line running down to the bottom of the screen. I guess we need to call tech support.
