I have the exact problem with my Breakshot. The GI lamps around the slingshots were working (orange wires) then as I began replacing other GI bulbs, they seemed to dim and sparkle and have since gone dead. Most of the lights are working but it just seems to have affected the bottom GI lights not coming back on. I took the board out and reflowed the 4 main capacitors which appeared to smarten up the random rebooting but my lights and right flipper never came back to life.

The right flipper is an anomaly...it's never worked since I've picked up the machine. I recently rebuilt the flippers including the eos leaf switches but it's made no difference. The upper right flipper works and I can control the diagnostics menu with it but I can't get it to engage the bottom right flipper. It appears all the connections are right as I have noticed in random tests, when manually tossing the ball at switches, both bottom flippers will engage on occasion. I don't think it's a random engagement from recall as it is triggered by something I did with the ball....can't remember.

Any ideas or should I start a new thread?

Solved:
Turned out that it was the previous owner/repairman. Didn't notice at first but they had replaced some Molex connectors on the main board. I presume they thought they knew where the wires were supposed to go or someone had tore them off in a hurry of something. Anyway, there were 4 different connectors that had wires going in every direction other than where they were supposed to. Found the wiring diagram and fixed most of the problem so in the end, my problem is not related to the original posters.

LOL...ya, that's where I thought I was heading. Got most of it working but still have a few kinks to work out. I've started another post regarding the remaining wiring issues: https://pinside.com/pinball/forum/topic/breakshot-pd-board-wiring-issue

You don't happen to still have the game do you, Law?

Oh, that right....you have a Pinball Magic...sorry.
