I just picked up two WMS BB1 machines. These are my first WMS BB1 machines. I was told they did work and the batteries just needed to be replaced. When I picked them up both monitors where working. One had call attendant on the monitor and the other had a bunch of text on the monitor just like they are in the pics. When I got them home and turned them on the Wolverton monitor did not come on at all. I turned it off and back on a few times and the monitor never did show anything that I seen. Lucky Lemmings monitor came on the first time with a bunch of text and the boot seemed to stop after saying file not found or something like that. So I turned it off and back on and all the monitor showed was no signal for a second and then went blank. Nothing else ever came up on monitor. Both monitors were working so I don't think they are bad. I was wondering if there is anything that could keep the monitors from coming up. Any suggestions on how I could trouble shoot the monitors. Thanks
