Restoring my Silverball Mania....Playfield swapped, reinstalled before finishing the cabinet. After the playfield swap, I had a intermittent flipper problem where the flippers would go dead mid-game. I convinced myself it was the apron (new) touching the flipper switch in the cabinet. I wiggled the apron more toward the center and it seemed to solve the dead flipper problem. I played it for about a month then pulled the playfield out so that I could paint the cabinet.
This brings us to Sunday. I drop the playfield back in, assemble the head, cabinet harness was not removed during painting. I play a few games then notice the flippers were acting up similar to before but sometimes the flippers would come back and sometimes they would just feel weak. It did not look like the apron was touching. I messed with the EOS switches at the flippers, these are on the list to get replaced. I took a file to them (new ones on order) to clean them up a bit. I did the same to the cabinet flipper switches. I turn the game on and its dead... won't boot, no LEDs on on the MPU. Testing the test points on the rectifier board, I'm only getting 6vdc at TP2 (should be 230vdc).
I was planning on bringing this game to MGC in less than 2 weeks. I'm at a loss as to what to look at next. I checked over the rectifier board per Pinwiki. Replaced the diodes CR1, CR2, CR3, CR4 with new 1N4007 diodes. Still showing 6 vdc at TP2. I have since put new EOS switches in, playfield has been partially out for all this testing.
