I have a High Speed and when my kids were playing they screamed as smoke came out of the top. I saw that the beacon fuse blew (the motor for the beacon is locked up). It also blew the F2 fuse on the PS. I replaced those and have the beacon disconnected until I get a new motor for it. Now I have an issue with the display not lighting up. You cannot play any games or get into test mode. I found a fuse towards the bottom of the back box that is blown it says 2.5 Slo-blow so I replaced it and as soon as I turned it on it blew that fuse. I have not idea where to look to find this short as the game was working great up until this issue. Here is a photo of where the fuse is located in the box.
Any help would be greatly appreciated!
