screen fades to black from left to right
my Samsung 60” led tv un60eh6000fxza picture fades to black from left to right but still has sound. If I shut it off and turn it back on I have a picture and sound but it fades to black after a few minutes.
ANSWERS:
"Hi @vshanewilk ,
If the TV is still covered by a warranty, get it fixed under warranty
If the TV is no longer covered by the warranty, try the following.
Disconnect the power from the TV and then remove the back cover.
Then disconnect the cable that runs between the power board and the mainboard.
Reconnect the power to the TV and switch on the TV.
All the TV panel backlights should turn on and stay on. There will be no picture as the mainboard has been disconnected.
If they don’t stay on check the voltage at the backlight cable connector on the power board.
If it reads no or low voltage then there is a problem with the power board.
If it reads high voltage (180-300V DC) then there is a problem with the backlights. There is either a faulty connection somewhere between the power board and the backlight array or some failing backlight LEDs"
It could be the power supply as previously suggested; it could also be the backlight circuit as well. If the LED backlight driver circuit is weak and failing, this circuit is most likely your culprit. Bad capacitors could be at fault in either circuit.
