I've got a Game Maker V7200 with a monitor not working. Took it out and put it in another machine and it still doesn't work. Put a known working monitor it that machine and it works. When the machine is powered up I get all 4 green lights to come on - on the main board but I don't see any small lights on the monitor board or any other board. I check and made sure it was in all the way, checked the monitor inline fuse, all of the connections are connected and all looks to be good to this point. Is there a trouble shooting procedure I can follow or anything else I can check? To me it seems like I'm not getting voltage to the monitor or monitor board. Maybe I have a issue with what looks to be a black coil or power pack?
Thank you.
