Question about Flat Panel Televisions
Please follow these steps:
ONE: Take the power cord from the tv and plut it into another outlet. If that is not convenient, then using a lamp with a known good bulb in it, plug that lamp into the same outlet the tv is using. This will verify the power availability.
TWO: Then, if the power cord is one of those that unplugs from the back of the set, you may be able to buy a replacement or use this one on another product to verify its working ability. If you have a VOM meter you could check it for continuity. The power cord can often go bad by itself. The most common problem is the molding machinery that applies the plug on the end of the cord. If they crimp the cable too hard it can cut through some of the strands of the copper wire inside; then overtime the rest of them break and it goes totally open and you lose power.
THREE: Check for a bad fuse on the back of the set. Then check the owners manual to see if there are fuses inside the set that are user replaceble. Be prepared to replace the fuses; but buy a couple of extra ones because the cause of blown fuses are to be determined.
FOUR: By now you should have some idea of the problem. The above steps were to determine conclusively if the problem is internal or external. The power cord is "external" to the tv. If the power supply were defective, this would be an "internal" problem, for example.
If the problem is internal, you will need to have a technician come in and look at it. There are too many things that can make the set fail. The power supply is one, of course, but there are many parts within the supply that could be the problem. The power management circuit could also be the guilty party. And there are other potential areas of failure.

It most likely is your fan. Your TV most likely overheated and shut down by itself.
If you still have a warrenty on the TV, call them and they will replace it for free (or whatever your warrenty claims). If it is not covered by warrenty or insurance, then you will have to find a new fan. Try eBay or Amazon.com.
