Cold weather and TV's/Monitors

[johnny]

Does cold weather affect television sets or monitors? It was a really
cold day yesterday and my TV picture turned into a rolled up one when
I turned it on and now it won't go back! It's weird looking. It's
like as if the normal screen is a sheet of paper and then if you
rolled that into a tube then that's what my screen looks like. I'm
asking about monitors because that happend to break down too although
I don't think it had anything to do with the weather. I hope I'm not
becoming electromagetic man or something like that!

johnny:
Just how cold did the TV get?? Is the problem still present even when the
TV is in a warm indoor environment? If so, there is a component or
circuitry failure that needs to be fixed ........ at the very least you
should take it to a repair shop for a repair cost estimate so you can make
an intelligent repair decision with facts instead of internet guesses.

Did the TV itself get cold? Just how cold?

The cold could have caused a trace or bad solder-joint to open. You
could even have an internal failure in a component.

Another possiblity is that condensation formed. When you turned it on,
you could have caused a short circuit and blew something out.

Probably just a cracked solder joint in the vertical section.

Condensation is the best explanation. This will cause short circuits all
across the pcb traces especially in the higher voltage areas...

You should always leave equipement warm up to room temperature very
gradually, say perhaps 30 minutes or more, before turning it on.

VCR's used to have a dew sensor to keep them from operating so the tape
wouldn't stick to the condensation on the cold rotating head drum.

.... Well I defragged my TV and went all the way back to basic cable!
