Hi guys,
Norway calling! My IJ has been resetting lately, so I thought I'd go the route of recapping the power driver board. I bought a power driver rebuild kit from Marco's (http://www.marcospecialties.com/pinball-parts/WPC-PDA12697X) and went to work.
I replaced the bridge rectifiers (green in my picture) and the capacitators (yellow). I had a hard time of getting some of the old parts out, but I thought I was in the clear when it comes to loose solder pads and such. I'm fairly poor at soldering though, so some of the solder joints were not as pretty as they should have been to say the least.
When I was done, inserted the board into the machine and switched on, there was an instant loud crackle in the speakers, and the display flashed and went dead - except for a couple of dots which seem random. No bootup or game sounds, no playfield action. Nothing really. Some of the leds on the board remain lit though. I was hoping you guys perhaps could help me with a pointer as to which caps or bridge rectifiers are the culprits by looking at the leds that are lit (red in my picture). All fuses check out fine as far as I can tell.
Any pointers would be great! And should_ I have messed up some solder pads on the board, is that the end of the line? Or is the card salvageable with skills lower than average?
Cheers,
