Found bad and replaced in power supply:
Q943 (C2240GR)
Q912 (D2088)
IC901 (STRF6626)
PC901 opto-coupler (TLP621B, NTE3098)
These above parts brought it from totally dead to repeatedly clicking
when plugged in.
Final parts:
PC902 (other opto-coupler, same part # as PC901)
IC941 (SE135N)
Unit now powers on and all functions work.
Note: I don't know which of last two parts did the trick,I don't want to
play "swap" at this point.
I know opto-couplers commonly get hit as does the SE135's with
lightning so it's a mute point.
Done.

Started by replacing the STRF6626 (IC901), and the opti-coupler
(PC901)P621.Then off the opti-coupler found shorted transistor Q943
(2SC2240 = NTE90, NPN). Replaced it, now plug TV in and slow repetitive
click-click happens only.Is there any typical surge damages that have
been noted on this AV32150 TV model?
Thanks,
Phil Bader
