There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.
The TV is a plasma screen. There are several circuit boards that will go bad over time that affects the picture quality. TV Parts Universal TV Stands DLP Chips ShopJimmy You can get the parts here and replace those boards yourself.
It might also be a bad solder connection, short of checking voltages what I have done in this type of situation is with back off use a small fairly high speed fan - a hair dryer set to cool works, to cool areas of the boards inside to localize which board is causing this, with the set in failure, got it? it goes out cool it with a handheld hair dryer with air set to cool, when you find the spot where the problem is it will either instantly come back or try to.
Do it a few times to confirm which board is bad and locate a replacement board and swap it out.
my 46'' inch tv polaroid lcd has been working fine for 3 years. today my wife and I noticed the tv is shutting off the screen will go black and the power light does switch to red. you can here something inside the t.v clicking but you can turn it on and it will start back fine for 20 minutes then shut off again? Does anybody know whats going out on the tv? let me know
or a new lamp. you could first replace the lamp. the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck
