Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.
Replacement boards can be found at a good price at Shopjimmy.com

Check the power board for capacitors with the tops bulged up. They are 3300uf 10v. There are either 2 or 4 of them depending on your set.
