Just flashing LED lights
Samsung UN70NU6900FXZA
I was only getting a flicker from the LED backlights. I have replaced the main board and the power board. It will flash the backlights. I had sound going after I checked the ribbon cables again. Then I turned it off and the the lights started flashing again and no sound. It’s not a strobe type flash it’s just on and off, they do dim down before going completely off. I disconnected one of the ribbon cables and the sound comes back on. So reconnected the ribbon cable and disconnected the other one and I still get sound but no picture. The backlights do operate normally with one of the ribbon cables disconnected. Do I have bad ribbon cables or is it something else?

@bderby which ribbon cable did you disconnect and where did you disconnect it? Since you already replaced the main board and the power board this is an odd error. The backlights failing has no relationship to the sound. Again. We need to know what the exact model of your TV is.

Sorry I had it on there and had to redo everything and forgot to put it back on. It is a UN70NU6900FXZA. The ribbon cables are from the main board to the PCBs along the bottom of the screen.

I have this same TV and tried the same troubleshooting. If I disconnect either ribbon cable I get audio but no video.
