Awesome!....Thanks heaps.
OK. Little bit unsure which LED code failure I should take note of (maybe both)....Its flashing 3, then next cycle 6. A 3 flash is the U51 PIA failure (score display circuit) and a 6 flash is U42 (sound board)....The score display circuit makes sense if the screw theory is right....I'll try to comprehend my way through the schematics to see whats before / after the U51...Also building an external power supply (off my computer) to drive the CPU board....
Will post more photos of resto shortly!
