We recently had a thunderstorm. When lightning struck nearby my TV turned off. After restarting, it went into a boot loop. It turns on, the logos displays, the smart bar at the bottom displays and I can get into the menu. However after a few seconds, the TV shuts off (you can hear a click when it shuts off). It then restarts and does the same thing, over and over. My video of what is happening here: My Samsung TV Bootlopp
I have tried resetting by unplugging and holding down the power button. I have tried resetting to factory settings, but it doesn't stay on long enough for me to make it to that part of the menu. I have tried resetting with EEPROM method, but no luck ( I think I'm doing it right).
Someone suggested to me the main board should be replaced as there seemed to be no issue with the power board. So I ordered one and replaced it, but I have the same issue, with even less screen time on. I also tried getting into the service menu, but it doesn't give me enough time to do a reset.
I'm not sure what else to try. Please let me know if anything comes to mind as a solution.
