Call me stupid (hey, stupid!) ---
two fuses in the power supply?!
One in the front part, easily seen...
one in the back, kinda buried...
and .... blown.

Replaced it. Turned TV on. It held.
Now I'm hearing a whine or a shrill
or a buzz coming from the area of the
large transformer in the power supply.

I think (correct me if I'm wrong) that
it isn't an indication of a failure in that
transformer but rather maybe an electrolytic
somewhere in the power supply circuit?
