backlight may have gone if your tv has one

please see your other post for response

Not knowing brand and model number most of these sets have a 4-5 year life and parts for a set of this age may not be available.

The risk in repairing a set this old is it may just fail again and again.

is this happened either watching a tv channel or even watching dvd movies?. and then does the display only white screen or a totally black screen?.

Does it make a squeal sound while plugged in to power? If so, possible horizontal output shorted. $150-$200 about.

Capacitors on the power pack are going bad they need to be replaced that should fix the problem.

HELLO.! IT SOUND'S LIKE A POWER SUPPLY PROBLEM TO ME.!!! & FOR THE TIME YOU WILL PUT IN TO IT & THE MONEY .!!! YOUR BETTER OFF GETTING A NEW SET.!!!HOPE THIS HELP'S YOU.!!!"GOOD LUCK"
