It sounds like your power supply is about to die or it has some capacitors that are about to fail.

You can check the board where the components are mounted and resolder any that look bad. a brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. all can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced.

SOURCE: my plasma tv switching off byself

Sounds to me like your internal cooling fans are not working. Try placing a fan behind your tv and seeing if it stays on longer. If it does then you'll know it's a problem with these fans. Not expensive to fix but not easy to do either.

If your tv is within the one year warranty period then call 1-800-Samsung for warranty repair. Look at your tv purchase receipt for the Purchase Date. You have one year from the date of purchase to get warranty repair.

heating up issue, try unplugging it and if you can clean the dust from within the unit. Try reversing the vacuum and blowing excess dust out.

Tv has no power, can't find reason.


they have little relays in them, kinda rectangle and tall on the board, you can peel the thin plastic case off the sides and manipulate the switch to narrow it down as to which one is bad.

Protron 42


on the back of the TV where the power cord plugs into the back of the tv there is a small black on/off switch- it's not as obvious as you would think.... but that was turned off. Not sure how that happened since the back of the Tv was never touched when it went dead- but I unplugged the cord from the back of the tv and from the outlet and reset that switch and it worked.

Sony KV-27FS100L -


This is due to switches malfuction due to corrosion in switch and dust accumulated in the switch. Since you rarely used switch now after failure of remote of remote control you tried to operate the switch. Another thing you said did"t get picture, maybe memory problem is there. This can be sorted out by the technician only.
