Lots of work involved in preparing this machine for sale! First, a thorough clean. This necessitated taking all of the ramps off the playfield so you can access all ball areas at the top of the playfield. There was some Mylar lifting in this area so that had to be removed.
Next, the drop targets. The "J" target was not staying up. The targets are meant to rest on a plastic shelf which keeps them in the "up" position. Somebody had installed a homemade version of this part which had cracked. Correct part installed and assembly rebuilt.
Next, the subway entrance. There were some lamps missing here which were reinstalled. There are also two small wire ball guides on either side of the hole which guide the ball into the subway. They had fallen out at some point and were in the base of the cabinet. They were re-tensioned and glued back into place. New rubbers installed while I had this bit apart.
Next, the lamps. Plenty not working, particularly those on the lamp boards. Cracked solder is common on these, particularly the lamps in sockets which are parallel to the playfield. Most of these needed resoldering.
Next, the Deadworld. It kept spinning and wouldn't stop to allow the magnet to pick up the balls. One of the optos under the playfield which reports the Deadworld position was not working. It was fouled up with dust and dirt which were keeping it "closed". Cleaned and back in action.
Finally, the flippers. Upper right flipper to be exact. This one was intermittently weak. A quick rebuild did not help. Test mode revealed the flipper switch was flaky. This switch is on an opto board. Rebuilt the connector and reflowed solder on the board but this didn't fix it. Turns out, the opto itself was on the way out. Replaced it and all was good again in Mega City One.
