This problem is commonly caused by faulty power supply, remove the back cover of your tv, be sure to unplug the unit before removing the back cover. Then follow the A.C cord of your tv, you will see the power supply then observe the parts specially the capacitors if you see bulging or leaky capacitor replace it with the same type and observe the polarity. Or you can also check the solder side of the pcb of the power supply then look for loosed or cold solder.

Samsung TV turns itself off every 10/15 minutes


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

TV Turns off and on


How long since the last time the bulb was replaced? It sounds like the bulb is overheating and triggering a safety shutdown.

It's probably in need of nothing more than a good cleaning (open it up, clean off the boards with a can of air) and *may* be time to replace the bulb.
