I can't locate the the thermal fuse on my sony kdf-e50a10 tv

SOURCE: Sony Grand Wega KDF-E050A10

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.

read this if you think it's the same problem

Replace the lamp, sounds like a weak or old lamp. Use an original Sony, the replacement lamps are unreliable
