Great video...I have a Samsung 75" Q70R and it went black screen while watching a movie, it flashed blue every 20 seconds, I have some knowledge in electronics so I opened it to see if it had bad capacitors. With the TV energized, I disconnected the ribon cable that goes to the main board and the screen turned blue, so I assumed it was not the damaged screen, I have been looking on ebay and I have found the original power supply parts, do you think that replacing the board will solve the problem?...thanks
