The TV turns on and off after a few seconds and repeats itself.
I have a Samsumg HCN653W rear projection TV that does not turn on. When powering up, it turns on for a few seconds then it turns itself off. It keeps repeating the same sequence until I manually turn it off. I hear a little bit of sound just before it turns itself off. Do you know what the problem could be? Do you have a service manual for this TV?

Re: The TV turns on and off after a few seconds and...
There could be quite a few things that would cause the set not to power up. I dont have the service manual, however you can get a copy of the service manual at the following link for your model. As thats the only proper way to be able to check for the proper voltages to determine whats wrong with the set.

IF model number posted is correct and green power light comes on for a few seconds and then goes off: On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.
Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.
Let me know what error code is found and I will tell you what it means.
there is most likely a bad connection on the power board. i really suggest not letting it do that all night unplug the tv it can do alot of damage to the tv if it cycles like that for long periods of time.
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.
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.
