I have a RCA 65” LED TV, every time when I’m trying to open my TV, the back light just blinks once then turn off after. The sounds and Video are working properly, only the back light that is not working.
I tried replacing with new power supply , but i didn’t changed anything, the problem is still the same.
Any suggestion is highly appreciated.
Thank You.

@techvictor “the sounds and Video are working properly” and ”I tried replacing with new power supply” and if you have no change with that it is most likely a failed backlight array (backlight stips). I suggest to get an inexpensive backlight tester and check it out or go ahead and replace the strips hoping that I diagnosed this right ;-).
