BACKGROUND FROZEN When you turn the TV on it stops at the blue Mitsubishi screen and the power button just blinks. You have to then unplug the TV to power down. Pushing the power button on the TV or remote will not power down. TV is only 1 year old. Prior to now it would shut down prior to the blue screen. The fan is working but TV still produces a lot of heat.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
