I think you need to exchange the Main Board.

Check the fuses on the T-CON board and also verify that it does have 12vdc feeding it. If you look at your screen in darkened room you will probably see slight glow on the front of the screen.

I have a Samsung 32" LED tv model number UN32F5500FXZA. It has sound but no picture but passes the flash light test. I don't see any backlights. Any idea what the part is?


The backlights are located around the edge of screen inside the tv. Now this model is know to have LED failures. The LED strips are you backlights. The LED strips are powered by the power supply board but due to the fact that this model is know to have LED failures, I would recommend replacement of the LED strips, all of them, first.

TV Samsung 50 UN50EH5300FXZA BJ04. Sound but no picture. Replaced all boards, still no picture. Flashlight test saw image.


Hi Rick,
It appears to be a case of backlight failure. since you have replaced all the boards, inverter is ruled out. Some of the LEDs in the backlight array may have gone bad. Fault is repairable, but needs care and experience of opening and repairing the LED panel. Good luck.

If you see a picture with the flashlight you can rule out the T-Con board. It's working. So the led driver board is the problem. TV Parts Universal TV Stands DLP Chips ShopJimmy Go here for replacement parts.

How do I fix samsung tv no picture just sound


Since you have replaced the LED board and you can still see a faint menu screen, this would indicate the LEDs have blown! Replace the backlight LEDs.
