If the blinking light seems to be blinking in a pattern, then it is an error code. The end result in any case, is the main power supply is not functioning properly, or the backlight power supply has a problem.

Most likely the TV has a power supply related problem. It can still have a problem without blowing the fuse. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and 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 red light blinking codes, circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.
I hope I shed some light on the subject for you.

I have Philips 50 inch plasma TV purchased almost exactly 3 years ago. Completely out of warranty. Paid 1999 bucks for it new. Now Plasma TVs similar to this are 800 bucks. I figured the cost of a repair tech coming to the house would be around 500 bucks.. so I decided I could "do no harm" and look at the power supply. Sure enough, two 3300 uF caps were swollen.. I am far from a true electrical repair person, and if it were not for the caps being swollen, would have no idea that they were bad. I am however a little bit skilled in soldering. So I ordered replacements for about 8 bucks. The caps were actually only 1.50 ea. but the min order fee and shipping brought it to about 8 bucks.. I got them from studiosoundelectronics.com . They came in today and installed them... to my astonishment, my TV works as good as it did when it was new... I must say that I am dissapointed in Philips.. and will never buy another product from them. If it is out of warranty.. they will not even talk to you.. I don't think it is too much to ask when you spend 1999 bucks on a product from them.. I expected my TV to have more than 2.999 years in life in it. Thanks a million to this site for providing soulutions for folks..
