Hi everyone! Just picked up a high speed this week, my first personal pin! (Work at a bar with a handful I do basic maintainance on)
Game was playing fine for the first few days, then periodically after playing a handful of games, it would freeze up. Display would stick where it was or go blank, all the lamps would stay stuck where they were, but the the solenoids would still fire. A power cycle would fix the issue and it wouldn’t occur for quite a few more plays. Have seen this be an issue while trying to search through here for a few other people, not with the machine so first thing I’m going to check is the 5V on the power supply to make sure that’s good.
More importantly had a friend play a game, it froze up while the ball got locked in the hideout, then when game was turned back on it tried to ball search it and didn’t kick out. Since then neither of the the hideout lock solenoids fire, nor the kickback. All the switches are fine and registering. In solenoid test mode you can hear a light click when it tries for both hideout kick outs and the kick back.
Checking out the backbox everything visually looked alright, other than this one corner of the power supply board. Looks like the wires have a little space and have burnt in a bit. Could a hard slap save be enough to cause them to not make full contact momentarily and cause the freezing problem?
Let me know what other details can help, haven’t done a lot of work on system 11’s, or much past flipper rebuilds, resoldering connections, couple power supply swaps, etc. so still pretty novice.
Thanks in advance!6524AA7F-5B8F-4DA4-A768-0F9ED07E9A56 (resized).jpeg
