Re: Sony KDL 60EX720 with 2 blinks but not the prblem from service manual

One final note regarding Sony. The whole reason I had this TV in the first place was that my original Sony had the problem with the green hue that was an extremely common problem. So much so, that it had a class action lawsuit and so they offered a discounted new TV as a remedy. When I got the TV, I wasn't given the option to buy an extended warranty and wasn't even given a receipt that showed how much I paid for it.

Re: Sony KDL 60EX720 with 2 blinks but not the prblem from service manual

Re: Sony KDL 60EX720 with 2 blinks but not the prblem from service manual

Trying to upload service manual to see if I can. Guess I can't.

It also has a G8 board that is the LLC resonance circuit board and provides the 24V regulated. This board still was providing the 3.3V STBY, of course since I was getting blink codes and also the AC off detect 3.3V.

I ordered a NEW board (not Ebay) and when I installed it, it did nothing. No picture, sound and no voltages except AC to main rectifier and a rectifier output that is low but no DC outputs....
