Hello. I have a TCL 65r615 while watching tv there was a loud “pop” followed by unit shutting off. It is now completely unresponsive. Also smell of burning from inside tv right after. Assuming it’s probably the power supply board but not sure. Rookie at this stuff. Any help would be great thanks. Images of boards included.
@galreth R404 and R405 look a bit suspicious. Remove the power board and post some more pictures from the sides so we can see the tops of the capacitors as well as the underside. Ultimately I am agreeing with you that this is most likely a power board issue. Schematics are not to be found for your power board so we rely on your pictures.
