Because of the age of your set I am incline to believe you have a loose conection giving you this symptom and if I was doing the repair it will be the first thing to look for ,I am sure I would find quite a few ,resoldering them will prevent more expensive repairs and likely take care of this one.If you are familiar with tv service this will help you but if you are not seek assistance from a servicer.It should not be expensive.

Tv Turn sound on, No Picture, turns itself off within seconds


The TV is trying to go on protect mode because an internal fault had been detected. For that reson the protection circuit keeps turning off TV continuously.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

Samsung LCD tv - Turns on and off by itself.


Since you have another TV with the same problem you can try using an antenna(indoor model ok) to see if the cable is causing the problem. If not return TV before the warranty expires.

Tv turns on by itself


Hey Bubba,
If your TV is turning on by itself at about the same time each day you may have a timer activated, turn it it off, the TV's micro might need too be reset. To reset unplug your TV from the a/c outlet for at least 5 minutes.

Vizio LCD 37 Inch Turns Off Randomly


I had a similar problem with my 32 inch plasma tv. I called vizio's
1 800 number and the guy said to unplug the tv from the wall and hold down the power button for a minute and then plug the tv back in outlet and turn on. And it works I guess from what I understood from his heavy accent was that the tv retains power and this resets it somehow. hope that was helpfull!!
