The 3 times flash LED is a error code. That means the backlight LED bar is open! (this set has two lines) Then the processor switch off the set. (No video and audio working remote controll only. Pleas check all LEDs on baclight bar. one or more LEDs are bad.

Hello!
Take off the LCD display you can see the LED bars only. Swith on the set and check all leds how does it work. When start the set all leds light max britness and some seconds stay back half britness and stay on. If the inverter circuit swith off then are defect somewhere in backlight system.
