LCD screen (backlights I guess) immediately turn on when the TV is plugged into the wall, but there is picture or response from power button. This particular TV was a casualty of a severe thunderstorm.
I’ve checked the power board and the main control board - neither seems to have heat damage. The fuse shows 0 ohms on my DMM, so I think it’s still good. Tried with another fuse anyway. Disc Capacitor in EY25 & EY26 heats up quickly. I don’t see anything else unusual with other components on the power board. I’ve unplugged the cable to the main board, but problem persists.
Before I try replacing the boards, does anyone have any suggestions?
