I'm having the same problem. My flippers dont work but instead activate the Ripper kickback. My trigger/laucher also isn't working. This was fine before transporting the machine home. Did you ever figure out the problem or solution.

Anyone recommend where to start?

Reseated or checked for a broken wire on MPU board connectors CN8 and CN10? Those are the switch matrix inputs.

I took a quick look and all seems fine. Thank you for your suggestion. I will try to troubleshoot further tomorrow. Sucks as im new to this and the machine was working before I brought it home. I hope this doesn't scare me away from the hobby.

thanks again!

After more digging I found out the following issues:

Magnet, laser kick "ripper", Auto launch, Right VUK, Right Scoop all fail to function. Other than the laser kick "ripper", all share the same yellow-violet wire. The ripper has a violet-yellow wire. The 5a F5 fuse was blown and when replaced it blew again. The Flippers don't function and still activate the ripper coil but at a lesser force. I can't seem to find any crossed wires. I am not sure what to do next. Kind of overwhelmed at this point.

Anyone have suggestions on what to look for next?

Granted that the ribbon connectors are installed correctly (and the connectors themselves are good) in addition to connectors CN8 + CN10 installed correctly and in good shape, i would check *all* of the switches and their diodes on switch row 8 since the problems all seem to have a common thread there.

The auto-launch button, the ripper, and the right flipper button are all on that circuit. It's important you check the other switches on that row as well, because a shorted diode, wire, or some other problem with *any* of the switches on that row can create havoc elsewhere with switches on that same row.

So I'd suggest checking all those switches (numbered 8, 16, 24, 32, 40, 48, 56, and 64) and verify the diodes are firmly connected and have correct orientation, and also that the wiring is correct at each one and firmly connected as well. Make sure none of the solder lugs on the switch or wires or diode legs are contacting anything nearby.

Did you reflow the header pins for cn 8 and 10? If so, check for any possible bridging between pins on the solder side of the board.

Any update ? I have the same problem .. flipper don't work and ripper activate when use flipper... and trigger doesn't work also
