No Backlight and No Image But Has Power
TV Model: PS59D8000
The TV turns on then it turns off after a short while. If I unplug the black cable to the tcon board as shown in the image below, it turns on and stays on.
I have unplugged every other board and it does not stop it from turning off. Nor does it make the backlights work.
I am curious to whether the tcon board is what sends the signal to allow power to the backlight? I know it processes the image, but does it determine whether the backlights receive power? If so, I believe it could be the tcon board, but I am new to this. I also replaced the powerboard with a brand new one, which changed nothing.
Here is the entire TV backpanel:
Any help is very much appreciated :)
Is this a good question?
