After diagnosing that there was a failure on my "G" board I bought a new board from Sony
($260.00) after swapping out the old board for the new one the TV worked for a few minutes then I turned it off and danced around the living room feeling very good about my repair work. Then an hour later I went back and the TV won't turn on and is giving me the same diagnostic code as before the board went out.
Four flashes
4 times, pauses and repeats Set turns off. Vertical failure (the horizontal could also cause this since the power for the vertical comes from the flyback)
(Vertical failure) Vertical Output failure
IC001 damaged
No vertical drive from IC301
No vertical B+ from flyback
No horizontal drive
What is going on?
Thanks in advance for your time in responding!
