A couple months back I bought a Defender off of e-bay. I got it for a very reasonable price of $299.00. It was in good shape but the CP had some serious cigarette burns on it above the player 1 and 2 buttons. It was noted that the game occasionally reset itself during play, but very infrequently. When I got it home and fired it up it played fine for a few days, then it started to reset often. Then it got worse to where you couldn't even get through the first wave without it resetting. Needless to say, it was frustrating.
I asked on here what to check on and got a lot of ideas on what to check, as it sounded like a voltage problem among other things. As usual the board gave expert advice about what to look for. Things got hectic and I forgot about the game. I was having some company over tonight to play some games and thought I'd try it out again and of course it was just as bad as before.
It's always bothered me that the coin door is very loose, like it was pried open at one time and moves a good 1/2" or more, even when the lock is locked. I got to thinking that maybe when the door is jostled during game play that it might move enough so the white button that the door depresses might be affected. Don't some of these games have a slam switch detector?
Anyway, I decided on a whim to use electrical tape and tape the white button down as tight as I could make it. BINGO. The games been playing fine all day since. Hasn't reset once. I've played 25-30 games on it total today. Can it be as simple as that?
