I'm not sure what my issue is, but some basic troubleshooting has yielded nothing so far. On my Mr & Mrs Pac-Man (which I have rebuilt most of after fixing the cabinet), I had flippers working yesterday, but today they are dead. None of the three flippers activate. Here's what I've checked:
- Confirmed voltage at the flipper coils
- Playfield 1A fuse confirmed good
- Getting proper blinks on Alltek MPU
- Everything appears to be connected and wired properly at the flipper coil/switch
- Voltages on the SDB appear to be ok: TP1 5.2v; TP2 176 v; TP3 5.2v; TP4 252v; TP5 15.6v; TP6&7 5.2v
- All connectors have been repinned (except for the Rectifier board), including J2 on the SDB
Any other thoughts what I might check next? I thought maybe since all the flippers are out it may be a relay, but I am unsure. I also don't know how to check that. I will go through and check the transistors on the SDB, but since it's all three flippers that seemed unlikely to me.
This appears to be the only issue I have at this point...although I have one display acting strangely (player 3) and I'm not displaying my "millions" digit on the 7-digit displays. (These are all new displays).
Here's a link to a quick video of the power-up sequence. You can kind of tell how it seems a little quiet. No flipper coils activating. And you can see the display issue (the displays look normal, the video just renders it weirdly). Thanks!
