There are a couple of ways you can give your Ms. Pac Man game credits:
1.) If you can open your coin door, you should see a coin mechanism attached to it. At the bottom of this coin mechanism should be a small, thin piece of metal that looks like a paper clip. If you push this piece of metal down and to the side it should simulate giving the game a quarter and allow you to play.
2.) You can wire a push button to the wires that attach to this part of the coin mech to allow you to coin it via the button instead of pushing the wire down. Some games have a service credit button that will do the exact same thing located just inside the coin door so you might check for that.
3.) You can set your dip switches to free play so that you don’t have to coin up the game to play it. If you set dip switches 1 and 2 to the On position on your Ms. Pac Man board that should give you this option. Please see our post on Adjusting The Dip Switch Settings On A Board for more information.

We have had problems with discoloration in sections of our monitor due to rebar running through the concrete foundation of Tim’s gameroom. One thing that seems to fix this problem is if we rotate the position the game is facing. While this may be a long shot answer, it’s definitely worth a try. You could also have a problem with the shadow mask in your tube. Check out this Wikipedia article for more information: http://en.wikipedia.org/wiki/Shadow_mask. Since your monitor is relatively new, you might trying contacting the manufacturer and see what their thoughts are on your problem as well.

The smaller degaussing coil should work fine for all of your monitors. For some reason Amazon.com lists this degaussing coil as only working on 19″ monitors or smaller but we have successfully used it for pretty much any size tube. Of course, the bigger the coil you get the more of an effect it will have on the monitor but overall any degaussing coil you get from a reputable source should work on all your monitors.
