Getaway owners - you may want to check your ramps for voltage! Put your red meter lead on the metal ramp and the black lead on ground. If you measure 70V DC then you may have the same issue I did.
I had my switch matrix blow up (U20 chip) 3 times. I would replace the chip and spend hours going through all the switch wiring without finding any problems. Game would play fine for days then bam! Turns out the diverter coil mounted under the ramps can rotate quite a bit. When it does, the coil lugs make contact with the corners of the coil stop. That can electrify the ramps with 70V DC. Then, if a switch touches a ramp, bye bye U20. In my case the back of the green standup target at the pf top (when hit hard) could briefly touch the edge of a ramp mounting corner. Another standup target located just below the pops had a similiar potential. I took a dremel and cut off the top corners off the coil stop so the coil can now rotate from side to side without the lugs making any contact. Make sure your getaway ramps are not electrified!
