Doesn't power on, flickers on and off
I got a UN70NU6900F TV, it has the same problem. I got it to temporary fix if I unplug a display cable on top while the TV power is on (flickers) and plug it in again. I got the picture (but if I restart again, the same problem repeats). For reference, I also found a video: https://youtu.be/zGAVbMQrSek , at about 8:40 timeline, that is the cable I unplugged and plugged in. This temporary fix it I tested and got everything working and the picture shows up nicely. Only when I turn the TV off and turn the back on again, the screen start to flicker again, not sure what is the issue with that? Is it a bad connection, the motherboard problem, or the screen panel problem?
