may be the fans are blocked or malfunction.
Don`t continue using if is overheat, you can broken others parts.
I recommend clean the TV, put the blower or aspirator near the vents air (slots for ventilation).

If you can dissamble the TV, remove the fan and check it or replace.

You can buy it at your service center

I am sorry to hear regarding the trouble. This is a common problem on Samsung plasma TV's. Though without being there, i cannot provide legitimate 2nd opinion, however i could add my input to the diagnosis. The major probability is always power supply board and main board. As you have eliminated the power supply board, the next major cause would be main board. Though, either sustain board or scan driver board could cause this issue, however on almost all occasions, when the power supply board is fine, main board is the culprit.Make sure that the controller board buttons are not sticky and remote buttons are not sticky.You need to check the voltage across these. The suspected part would have the power missing in it.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
