I have a Samsung 55" KS8000. I found it broken. When I came home I tried to fix it. I found it has sound but no backlight or image (I tried to see an image with a flashlight). Upon further inspection with a multimeter I thought it was the t-con board. However I replaced it and it didn't work. I got the board from eBay so it could have been a bad board. I just recently tried the power board. I tested the voltage of the power board where it conects to the LEDs. It shows the right voltage I think. It doesn't label the points positive or negative however. Three out of eight pins showed the appropriate voltage when plugged into the LEDs. However when I unplugged the LED to power board cable only one of those showed the correct voltage. Do y'all have any idea what it could be?
