My Samsung tv won’t turn on, the power led blink twice, I did open the tv and notice the following The back light does go full, dim then off. If I keep the power on, it keep going on the same cycleIf I disconnect the main board, the backlight stays full the entire time.Did replace the main board, and the behavior is still the same. I do have access to multimeter, any ideas what to do next? Btw, model number is UN55RU730DF
Update When I do disconnect any one one of wide cable that comes from main board to screen panel, I can hear sound and use remote, no image/video Thanks

Hi mate don’t know if you fixed this but I have exact same issue and everything you have done but while I had the ribbon unplugged the sound was there then I plugged the ribbon back in and I have picture too. I am doing an update now so will see what happens after that.
Sorry to say but Samsung products are horrible. I’ve owned refrigerators, tvs, dishwasher, dryer and washer set and all, I mean all have failed right around the 2yr point of their life span. My washer n dryer hurt the worst. When you are told, at less than 2yrs after you spend however much on the crap product, you now need to spend $300 on a part and $300 on the service you start thinking maybe it’s better to just take your tv and shove it right up Samsungs a$$. Stay away, stay away, please stay away from Samsung. Even with a warranty it and they will just make your life that much more stressful. Can’t believe Samsung is still in business. Buy the no name it will last longer
I had Samsung come in and diagnose the issue. Bought in November 2020. Apparently screen went. Samsung replaced the entire panel. They said the main board and power supply were fine.
