You have a bad optical block. Yes it can be fixed but you will need to ask around for the best quote as it is not a cheap fix. If its under any warranty Claim now

Yellow spot in middle of screen


Hi there,
We have the same exact problem with the same TV. We've only replaced the bulb once about a year ago. Don't know if it had anything to do with the fact that we now have a large yellow circle in the middle of our screen, which is about 7" round.
We only noticed the yellow mark about 4 months ago.
Hopefully someone will have a solution for us that doesn't cost an arm and a leg. Paid $2100 for this set and are a little disappointed.

Sounds like Calibration is needed on the projection internals. Your TV uses a rear-projection system and the problem is either in the imaging LCD Unit or the light filter. I see in a previous thread you have changed the bulb. You can invest in a voltage regulator to keep the hardware in factory condition.
Also you can burn a DVD of a stuck pixel remedy video and run it on the screen with full brightness and full contrast. This is used for plasma burns and stuck pixels on conventional Flat panel TVs but can repair color issues with projection systems. This therapy is focused on the imaging unit between the projector and the main drop of your tv.
please feel free to post a more in-depth description or any changes

Sony 60" LCD projection TV has yellow screen discoloration


It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

Sony 60" LCD projection TV has yellow screen discoloration


I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.
