Sony Bravia LED red light blinks 6 times (Backlight error)
When I perform a factory reset of the TV (by continuously pressing UP key on the remote and power button on the TV once), the TV operates normally for around 12-15 minutes. Then the display turns off and red light on the TV blinks 6 times (which I found out stands for backlight error).
There are no areas on the display that seem dimly lit when the TV is operational.
I tried disconnecting and re-connecting all the cables from the different boards just in case it was an issue of a bad connection somewhere. No help from that.
Resetting only solves the problem temporarily. This is what the self-check shows:
