Help me I have a TV that shows the android logo then turns off and flashes red 4 times i have done factory reset by pressing power and volume (-) button together, it fixed it but only a few days then come back again I researched and then bought the power supply board, I changed and still the same problem anyone have any other suggestions?
@alan31 For this model the most common cause for the 4 blinks is actually a failed T-con board. This model TV has issues with bad panel driver boards as well (not good). Those are the boards that attach to the display via very thin ribbon cables. At this time I’d suggest to at least try a new T-con board.
