Anyone know about TV repair?

Got a 36" Sony tube TV, house got struck by lightning, now the TV doesnt work. You push the power button, it powers on but no audio or video.

COuld this be a simple $200 fix? Is there some sort of internal protection that needs to be reset?

It sounds like it is more than likely DOA. The lightning probably fried some circuit boards.

There is usually an MOV (Metal Oxide Varistor) soldered across the line cord input at the power supply. Sometimes they work, sometimes they don't. They are supposed to "clamp" across the line cord when input voltage spikes beyond a certain point and they are "one time" sort of like a fuse. When they work, it's a matter of replacing the varistor. When they don't, (more often than not) there is damage done to the power supply circuit or even farther down the line to the horizontal output transistor.

Nobody's going to be able to tell without examining it. There's not much money in CRT set repairs these days, as replacement sets are fairly cheap. Some shops will provide a "free" estimate.

DO NOT try to fix it yourself, the CRT itself can store up a charge and you can get zapped even with the set uplugged. The Flyback transformer's output cable, which will look like a spark plug wire, should be avoided.
A power supply repair will probably be more than that set is worth...

I didn't read your post well, you said "it powers on" but that does not tell much. If the varistor got popped, the set is usually dead.

You probably have a damaged power supply module Danno...

My DLP TV was doing something similar but DLP and CRT are waaaay different.

Do you get an audible "click" inside when the power button
is pressed or nothing at all?

A lightning rod would have been cheaper.

A lightning rod would have been cheaper.

or a surge protector.

Thanks for the huge help Brother.

Russ, it does click, but no audio/video after that. He said there is a red light that flashes a "code", does that help at all?

Greg, thanks for the info.

Toss it. Like said above, DONT OPEN IT! They can get up to 30,000 volts in there unplugged. I would guss a voltage regulater on a circuit board got fried. It'll be more work then it's worth to track down the replacement part alone though.
