Such a common problem on all new Tv's in the 18 month 2 year age. I am sure this is built in redundancy!

Samsung are probably the best of all to deal with in the TV manufacturers world, so I suggest you contact them if its under any extended warranty .Otherwise use one of their suggested repair centres. The sustain boards have failed and the sensor is in protection mode to prevent further damage and possible fire. This is not a DIY and the fix cost is about $3-400. But get a few quotes first as there are a few crooks out there.

please rate my help++++Thanks for using FIXYA

Shuts down


Hi,

This is a typical symptom of a failing power supply. Replace your power supply and see if the problem still persists.

Please notify me should you need any further assistance.

Power supply board is the cause.The power supply board is shutting down,not giving the right voltage to the tv anymore.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

My television shuts back off when i turn it on.


It may thing there is short circuits, so the power supply shuts down to protect itself from further damages. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

I have a lg plasma,and the problem is it comes on for about 1 second then shuts off. repair shop says its the power supply? what do you think? the led is red when off and turns off white almost very light...


your power supply is shorted; remove it from the set and, have a TV shop repair it if you are unable to do the repair yourself.
any good shop can do the repair easily and, much cheaper than the manufacturer you can find the power supply by looking to where the power cord enters a circuitboard that will be the power supply

I went turn on my tv the picture came on then off


Picture turned Yellow because the Blue CRT stopped working. Power turns off because the power supply is indicating a fault. you probably lost your HT (high tension [voltage]) power supply on the blue CRT (picture tube). Professional assistance is recommended. HT power supply CAN DELIVER A LETHAL SHOCK even when the set is unplugged.

Brief power on then shuts off


It could be a component short or crack on the power supply board. Open the back of the TV and look for signs of defect. The power supply board is the brown one on the right with huge capacitors.

TV turns off


Sounds like a bad solder connection on power supply board. Remove the back, turn on the set,using the handle of a screwdriver tap the power supply board and see if it shuts down. The power board is the one attached to the power cord. If it does shut down, UNPLUG the set, remove the power supply, inspect the bottom of the board and look at all solder connections with a magnifing glass. Look for any dark rings around solder connections, and resolder with fluxed 60/40 solder. tonyfalcione@msn.com
