  1. Hello. Great teardown! I have a mi tv 3 60inch and have a problem with the tv signal output and image processing unit board. The screen doesn’t seem to recognise the mitv bar. Mi tv bar is working fine as I’ve tested it with another mi tv 60 inch screen. The mi port wire cable is working fine as well. Tv is turning on but cannot receive signal from mi bar. Im thinking to replace the board where the mi port is attached. Please help me in finding a board replacement. I would appreciate. I live in kenya and want to repair it.
    Thank you.
