Hello. My first post on AP. 

I am reading this with interest and maybe you can help? My revenge from mars has a problem. During game play it will freeze, sometimes after 5 minutes, sometimes after 5 games.  Pretty much the image will freeze and the light on the playfield will drop out

Can anyone else suggest something I can try.
Thanks.
