Question about Televison & Video
There are two possibilities for back light off after 2 seconds.
One reason is back light inverter boards got defective for some reason (this tv has 2 back light inverter boards on either sides) and second possible cause is power supply is not giving out sufficient voltage supply to back light board.
Let me know your expertise level to provide you more technical info.
