Authorized sony repair center told me the problem was the Q Box. Ever heard of this? Part runs about 300 bucks. TV is out of warrenty as it is 2 years old. Do you think it is worth it to fight sony and get them to replace the part or just fix the TV?

Part Number is A1167541A, service rep called it a Q Box in the diag, however the web says its the b block assmy.

This is caused by a failure of the optical block of your TV. The only way to fix the issue is to replace the whole optical block which is very expensive ($1000+) and time consuming (need to take whole TV apart to replace the part).

The optical block in your model had inherent issues and there is currently a class action lawsuit pending against Sony for this issue. Up to date information reguarding the lawsuit can be found here:

Optical block

I think, Lamp compartment locates at rear side near cooling fan. Open the cover and pull out the lamp. Please Don't pull HOT lamp.

You may want to have the optical block checked out. Usually when you see spots or blotches of color it's due to a malfunction of the Opt. Block assembly.
