picked up a Mystery Castle the other day replaced what I could find and it was working great until this morning. It's blowing fuse F6. The game won't boot up and because of this blow any ideas or anybody willing to help me fix it. Good news is I bought it with the idea of using it as a trade because of its rarity. So after I've fixed what I could I be looking to trade or part trade this game with my revenge from Mars toward a medieval madness. The game is in great shape with normal amount of cabinet dingsbut the side art is beautiful. The head needs black touch up. The playfield is very nice with the exception of the cracks in the ramps because they were made so thin and for those that know mystery castle and have researched it it's very common. on the playfield guy so I'm really happy with this playfield. The serial number is 3480 which makes it a earlier production game out of the so proximally 220 games ever made.anyhow send me an email if you're willing to help or willing to work a trade I got a lot of photos.
