Friends,

This set was left at my door (given to me) over two months ago.  Set
would click when powered on, but no high voltage and only a low-pitched
growl from the speakers.  I replaced the flyback (since I had one).  No
change.  At the suggestion of Wayne Vanaman from Omega Electronics, I
replaced IC641, SI3090, 874992058, on the power supply pcb.  Took care
of
the problem.  Set is now for sale!

Thanks, Wayne.
