Quick question for yeah. I have a 2019 Samsung 65” TV that’s having intermittent issues where screen will appear fine, then after a few minutes it will just go black, get the red dot on bottom of tv that flashes as well as the remote. Tries to cycle but won’t get picture. I took the back off, power board is fine, disconnected main board and I get back light. Tested the main board with FFC cable disconnected and light comes on good so I know it’s fine right to the main board. I tried the tape trick on the FFC cables and will get the screen to work for about an hour then it goes back to black again. I’m wondering if these are the issue as I plug them in and then the back light goes out and on again but as soon as I unplug the FFC the back light stays on and all is good. Are these FFC connections (some call them ribbons) a know issue to cause this black screen or is the main circuit board the culprit? TIA
