Hi. I have a Samsung LED 46" model #UN46EH5000FXZA, with no picture but has sound.I replaced the power supply board & T-Con board & still no picture but have sound. What can I do next??


Do flashlight test to see if y0ou can see an image - if so replace the inverter board that powers backlights. If no image then go for the main board.

My samsung un60hu8550 has sound but no picture. Just happened this afternoon. Sounds like a t con problem based on searches. Am I right, and how hard is it to replace?


It could be the t con board, the power supply board, the backlighting, or the display itself.

Don't open it up unless you know what you're doing. There are hazardous voltages even with the TV unplugged!

I have a Samsung TV model UN50H6350AFXZA which has sound but no picture. Backlights work. Replaced t-con board with new one, but not fixed. What next?


Main board. T con board is only involved with video issues. Main board goes both ways and since you already replaced the T con board that is your only alternative. U got backlite so inverter board is good.

Tv turns on with sound but no picture


if you have the backlight on but no image it could be the main board but if you don't have the backlight you have a problem with your LCD panel
the panel comes with the T-con board and the Inverter board

Picture died, no display only sound


Do this test and it should tell if the lcd panel is bad or not, turn the tv on and touch the screen in the center, push with your finger firmly but not to hard, if you have a backlight or light shows up around your finger then it is probably the T-con board/panel, the T-con board is attached to the lcd panel and is less expensive to replace, if you do not have any light then it's probaly the power supply
