Hi. I have done some searching and was unable to locate a fix. I have a 5010b that I just replaced the belts on, they were melted, crazy. It belonged to my grandfather and I want to get it going. When I press any button it does its job, that is to say the reels spin, but the buttons won't stay down. Any thoughts? I knew it did this prior to replacing the belts, but I was hoping the belts had something to do with it. Cheers.
