@octopie I am not really convinced about the random tests and the 18V being good. Use a multimeter to check for continuity (and voltage) of the fuses. Of course, look for any charred, burned, or missing component as well. Here is the schematic for the power supply. Go ahead and test the voltages on that.

@octopie looks like there maybe some damage on the board.

Check and see what is going on in that area

@octopie let's see this area (yellow outline) from both sides. Nice head-on pictures. That all looks like there is something going on. Water damage possibly, but it could just be my old eyes.

@octopie I am not really convinced about the random tests and the 18V being good. the attached image will show you ***all*** the fuses on your logic board. Use a multimeter to check for continuity (and voltage) of those fuses. Of course, look for any charred, burned, or missing component as well.

Hre is the schematic for the power supply. Go ahead and test the voltages on that.
