TV question

[Jon]

We had a thunderstorm and the power blinked on and
off. Then the TV wouldn't work.

The power switch relay clicks and clicks again after a
few seconds, but no sound or picture. It won't click twice again unless you
unplug it and plug it back in, and
then it will click twice when you press the power
button.

The fuse didn't blow and has continuity.

The transformer to the logic circuits is 18 volts AC on
the secondary. There's a larger transformer that
overloads the multimeter. All the diodes work.
Everything is on one board, except for a small board
that plugs into the tube.

Somebody said you can reset a TV. Does anyone know
how? It's a Sharp 26" color TV, model 25R-M100N.
Do you have any ideas on how I might fix the TV, or
determine whether or not it can be fixed?

There's no reset for this problem. It's time to call a Tech.

The clicking is, I suspect, the de-gauss circuit operating. Being a Sharp it
is unlikely to be mendable.

no sound or picture
Jon

"No picture" is not a valid symptom.
When you take it to the shop, tleel them
"No sound, white screen" or "No sound, black screen".
Entirely different problems.
