Tv flashes once when powered and screen goes extremely dark
Is there any way I can identify and repair my tv? It’s an LG 50LN5100 and when I press the power button the tv flashes brightly, then my screen becomes extremely dark.
ANSWERS:
"Hi,
It seems as though it is a backlight problem.
This could either be the Power/LED board or perhaps the LED strips themselves.
Looking at this supplier of replacement parts for the TV if your power board (see 1st item), has the same board number then most likely the problem is with the LED strips.
You could try using a TV backlight tester - examples only (videos on YouTube show how to use it) to determine if it is a LED strip problem or a power board problem, to avoid problems if you order the power board and cannot get a refund if it isn’t the problem. Just a thought."
