Samsung red light blinking

[tadams1404]

I have a Samsung unh556300af power button blinks 6 times no picture but does have sound.
I have done the flashlight test no backlights and was unable to see anything when pressing the menu button.
So I replaced all three boards and the power button and still have no backlights or picture any help

It appears you have a faulty power supply - send it in for repairs.

Check your warranty first.
