I recently picked up a Revenge from Mars pinball game. After driving it all the way home, I checked the connections to make sure everything was seated, turned it on, and all I got was the blue screen pictured below. I noticed that some of the LED lights are lit, which means the game is getting power. However, the screen is stuck on blue, with no writing, and will not boot up. All fans are spinning, there is a yellow light lit on the Prism card, yet the screen is just blue; nothing on the playfield is lit. I can't find any loose or disconnected wires, and the main 5A fuse is good. Im not very adept at pinball repair, so if there is anyone familiar with fixing these in the Los Angeles area, let me know. Otherwise, im looking for HELP from the Pinside family! Respectfully, Joe.

I took the advice that I got from several of you. Thank you very much for that by the way. I disconnected and reseated all the connectors on the game. I found the one computer plug on top in the back box was very loose. Instead of screwing it directly into the metal box, I ran the cord on the outside so they could seat more deeply. Looks like that was the culprit. Game fired right up and I haven't had any issues since! Love this community and the way everyone is willing to help one another.
