Tv turns on with remote but has black screen
I have a panasonic 42pz80u model and had a lightning strike. There was a 10 blink light at first but I have replaced the power supply, main board, sc board, and both y-buffer boards. The red light now comes on when using the remote but tv does nothing when using power button o TV. Screen stays black even when red light turns on when using remote. TV does not respond other than turning on. Don't know what else to do other than junk it.
Is this a good question?
