I recently purchased a 1980 Bally and all original boards had been replaced with Alltek boards. When I purchased the game, the seller informed me a switched playfield lamps wasn't working (actually, there were two), but hadn't yet explored why. After getting it home, and determining they weren't a bulb or socket issue, I replaced the Alltek board in the game with a new one that I had on hand. All lamps are now working well with the replacement Alltek board. Should I assume then that the issue is with the Alltek that was in the game when I picked it up?? If so, what's the best way to expedite a repair? I'm still real wobbly with electrical issues, and not real confident that I could somehow reflow a board, repair SCR's, etc. Nothing on this board I removed looks bad. Any feedback is MOST appreciated!!
