Quoted from Snowtrooper:Unfortunately it appears the problem lies with the MPU. As a last resort, I took my working MPU from my Haunted House pinball machine and swapped it into the Volcano. The green button on the right works as is should >>> stops the motor and running light (upper left drop targets) for the skill shot, and freezes the crater light when trying to lock a ball for multi ball. The tilt issue is no longer present.
So….can this be repaired? Can switch matrix issues be corrected? Or am I screwed and the MPU is faulty, and I will need a replacement?
I had a weird one with my Robowar, it would randomly reset during a game. All voltages checked out, the mpu had been repaired with new riot chips by the previous owner.
After much checking I narrowed the fault down to the spinner, every so often when you hit the spinner it would reset. I guess a RIOT chip for the switch matrix was dodgy, I have been told there are poor quality chips for sale. Anyway I bought a new mpu from myPinballs.com (Jim) and all is good.
I also bought one from Jim when I recently picked up a Gold Wings even though it didn’t need one. Much better mpu board, fit and forget!
