So.... I found a Tales of the Arabian Nights game a couple weeks ago on Pinside, drove the long drive to buy it and commenced repairing things. It played but the spiral ramp diverter coil was burned and froze and it almost looked like someone used a fire extinguisher on that spot. Ramp was garbage anyway so I got all those new parts, took it all apart and cleaned the playfield real good. I should mention that the quick test said “ramp diverter broke“, and “magnet broke”. It also said check two switches that I resoldered, and they were fine. (Oh and genie magnet hole broke, but it works fine). Got it all together and found that the magnet was just unplugged, so... everything worked great for two days. Only fault listed now was genie hole broke, and it wasn’t.
Today I was changing some backglass lights with the machine on and suddenly smoke and hissing from the power board, as one of large capacitors swelled and split...
WHY???! Now i don’t want to change anything out without knowing the cause, and I should mention that it’s a newer or at least not original board...
Can someone please advise me on where to begin?? Thanks!
