Hi modded my PC Engine, I switched over the PCB with multiple mods like the RGB Video mod replacement fpc ribbon, recap and the 78SR Voltage Regulator. I then put it back into it's new Retro Game Restore shell and then saw a pop in a fuse, I replaced fuse, went over my solder work, there were no bridges and the caps were installed correctly and the i tested again and the fuse blew again. I then noticed that I installed the faded out diode in reverse. I corrected the Diode and along with a new fuse, but now it no longer powers on. The fuse is still good and the same diode is now installed correctly. But it doesn't power on at all. Did something else fail in this console?
