Hi,
Does anyone out there that know of a tv repair service that can supply and replace the processor in a Sony main board?
Model # KDL-75W850C

I have had no luck in finding a replacement board for this unit.

Thanks in advance

Yes this is an android based system.
It was Diagnosed by a repair center in Tucson who explained that they thought it was the main processor.
Their term was a corrupted processor.

They were unable to get a replacement processor for the repair. ( also they the repair center had not replaced this item before as well)
The original failure mode was ( set was stuck in boot mode then detiorated to no pilot)

Anyway I finally found a replacement board yesterday so crisis averted.
Thank You for the response

Hello,
My KDL-75W850C looks like it has processor issues, It boots to Sony Logo, then powers down, and doing the 3 blinking red lights
Can someone confirm that that would be the issue?
