TV goes on by it self

TV turns on by itself. No picture and sound and few minutes the power light blinks off/on for 13 seconds and off for 2 seconds, then repeat itself again. Tried to unplug and plug back in but still no picture or sound. Turn tv off and few minutes later it comes back on again and repeat. Does anyone know what that mean or I have to a new tv.

Switch ON the set by its main power ON/OFF swith at its front panel [not with remote control], and count the number of blinks occur before the set shuts down.

2 Blinks: 15V SOS D_BOARD / P-BOARD.

3 Blinks: 3.3V SOS D BOARD.

4 Blinks: POWER SOS P-BOARD.

5 Blinks 5V SOS D-BOARD.

6 Blinks DRIVER SOS 1 SC BOARD OR D-SC FPC SC ENERGY RECOVERY CIRCUIT _ D-SC FPC DET.

7 Blinks: DRIVER SOS 2 SU-BOARD / SD BOARD / SU or SD CONNECTOR DET / SU or SD SCAN AND LOGIC IC.

9 Blinks: Discharge Control SOS D-Board.

10 Blinks: Sub 5V SOS/Sub 3.3V SOS A-Board / SC-Board / SS-Board / P-Board / MIHO 3.3 SOS / LED 8V SOS.

Count the number of blinks very accurately. Switch the TV OFF and ON; at least two times and count the number for confirmation.
