While playing waterworld randomly the flippers go dead then all the lights and display go out for a sec or two then comes back on and it's like starting a new game still in play mode but ball one and score reset. Could this be the pot on the 5v power supply?
Thanks

The door seems to shut tight and I thought of the switch but I rocked the cabinet and hit the door and couldn't get it to do it. Very random when it happens but I will try that and let you know

Update, i tried opening door and pulled service switch out as stated and it still done it.

I think you are on to something, with door open and switch pulled out if I'm on ball 2 and hit the start button it resets game like it does when playing in normal mode. The ship flips to deeds and you have to shoot ball but no flippers work then it flips ship to normal and your starting new game. A!l sounds and music working perfect, havent had chance to test power yet. Checked switch test all good, cannot get the start button to show on edge test but it works to acivate other test.

Would a switch on the ship cause this? I replaced all LEDs in machine and had to rotate it but I thought it back In right spot as it rotates properly when you in sink feeds and the normal mode.

It is a leaf switch, gapped about 1/8 gap, i thought vibration too but doesnt look like it as the leads are stiff and shaking cabinet by hand they dont move. Should it even restart a new game even by pushing the start button when playing? that part seems wrong. Maybe loose connection on board side that vibrates and activates the restart game? but seems odd a pinball would allow you to do that.

It doesnot shutoff and come back on the like a full power off and on, it simply starts a new game doesnt miss a beat. Flippers go dead ball rolls in trough dmd goes to ball one with reset score and ball kicks in shooter lane and your rolling again. So to mimic it on ball one i push start it just makes a ding noise but continues to play fine, once i get to ball 2 or 3 and hit the start button it will mimic the restart game. This something in the settings maybe? ill check manul but something seems strage.

There is a restart game setting in the settings menu i found in the book that allows the game to be restarted by hitting the start button. Maybe i can disable it and see what happens.

Yes the restart feature you described can be turned on and off in the settings i found in the manual just today and will be shutting that off but i assume something is triggering it randomly when its set on (If it is on in the settings) so shutting it off may take care of the issue. if i start a game and hit the start button on ball one it will add other players, the restart will only work if one of the players is on ball 2 and it will reset all players which would suck if your the the guy winning.
