Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board.
There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.

Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
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, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you the flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.
