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.

You might try pulling the AC plug overnight in case it is simply a 'lockup' of an IC. If it still will not turn on, it is likely that the main power supply has failed and must be repaired or replaced.
