My samsung lcd is doing the same thing, and I have been told that the power supply is bad. But apparently samsung won'r sell you one.

SOURCE: TV shutting off randomly
it looks like a faulty mains board. you need to upgrade the tv software with the latest update. if the tv is not accepting the upgrade then it can be a crook mains board.
hope it helps! please rate my comments :D

This is a DLP projection that has a ballast and color wheel along with a lamp. The three flashing lights on the front are a diagnostic code. The exact meaning is listed in the owner's manual under troubleshooting. I don't have the manual for your model with me at the moment, so I can't look it up. Since the unit works OK for a while, it suggests that a component is failing under heat stress. This is often the ballast. The ballast is the part that provides the power for the lamp similar to the ballast in a flourescent light. Check the manual for the code and post it here. Also, because your model uses 2 different ballast/lamp combinations, you will need to get the lamp number off of the lamp. Please post that here too.
In the meantime, check the rear area for any obstruction in the air flow. There should be a fan in the rear that needs to be clear of debris and can turn freely. With the set unplugged, try turning hte fan by hand. It should turn easily and continue on its own slowing down to a stop. If it stops suddenly, the fan may be defective and not moving enough air to keep the lamp cool.
Keep us posted.

Mine was doing that then it quit even turning on so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.
