Larry, I had one do this a while back. The fix was to replace Q604 2sc3311A (soft start driver) at pins 8 & 9 of IC651. Also, always ESR the electrolytics in the circuit and look for leaks, especially C651 2.2uF 160V and C613 100uF 25V. The two SE135 error amps are always suspect as well. I did the same as you, looked to the A board until a tech at sony told me to just change Q604, even if it checks good. Leonard G.
