I don't know that this is the appropriate place to ask but if anyone can answer my question it would be greatly appreciated--I don't know if I should junk this TV or not.
I have a 60 inch Samsung LED smart TV. The model number is UN60J6200AF. It has no picture, but sound, and the flashlight test reveals a working image. This model is known for LED strip failure but this is not the case if my testing is correct.
At first I suspected the power board. It has four wires going to the LED panel configured as 1-Ground-Ground-2. Power wire #2 has 450 volts, #1 has 0 volts.
When a wire is bridged from #2 to #1, the LED panel illuminates and the TV and backlight are completely functional? I replaced the power board thinking it was the problem, but it did not fix it.
The other visible boards in the television are a main board with the video connections and a T-Con board below. I do not see a separate backlight inverter or LED driver. Are either of these components primarily responsible for switching the backlight on/off? There is no visible damage to either of them.
