Here is a bunch of pictures made while repairing my Nintendo Popeye Cab.
Here's the chassis pcb, Audio Amp and inverter pcb. Capacitors, resistors and transistors was checked and replaced if defective
Checked cab for all parts. Video harness, audio harness and black bezel card is missing.
So I made a replacement cable for the video harness and a Jamma Adapter for a test game pcb. This way I know what is working and what's not. Checked psu and voltages. Finally I got this picture.
Result of this step.: faulty inverter board, faulty game pcb, faulty audio amp pcb and nearly defect Sanyo video chassis with vertical foldover.
