I've got two separate issues on two machines but I figure putting them in the same post will cut down on forum clutter 
First ZAXXON
I had this fixed not long ago by forum member Buffett who did an amazing job on this. But a short time ago the image suddenly went out. I don't think it's the monitor chassis as the neck glows and there is glow in the tube. The game plays however. I pulled the board out and it was rather dirty, I cleaned it up but didn't see much in the way of cold solder. I did not have a magnifying glass to really look at that though. Still, I would rather focus my time where the problem likely is so any thoughts or suggestions would really be welcome.
Second XMEN
XMEN 6 player just haven't given me a lot to be happy about since I got it as there always seems to be an issue. Since I got it there has been a weird issue where the controls on Storm and Nightcrawler I had to swap on the board itself otherwise when I would try to coin up on Nightcrawler, the game would reset. I tried moving the controls around at the connectors beneath the joysticks but no luck in making that work. So I just swapped the wire on the coin switches.
But today something very strange started to happen where the game started to reset itself anytime sound came on. I just got a second X-Men board in and the same thing happens no matter the board installed. From a little Google searching I can see I want to check the 5+ voltage but question is if its low, what do I do then? If its fine, what else can I check?
Thanks in advance!
