Outrun monitor flickers when using shifter, pedals, etc

[Ninten-doh]

Posted this over at KLOV as well....

Just put a used Vision Pro into my Outrun mini. Monitor looks great, but when I start playing, the monitor flickers when I move the shifter or hit the pedals.  This is probably the 4th monitor I've had in this machine, and all the others worked without issue.

I checked, disconnected, and reconnected all the ground wires, and the chassis looks good from what I can tell, and it's still happening. Any semi-hard shot to the cab (slamming the shifter, hitting the gas/breaks, and worst of all the shaker motor) causes the screen to flicker. So frustrating. I even had my wife stand in front of the cab while I wiggled some of the connections and none of that made the monitor flicker.

Any ideas?

might have something loose on the monitor chassis.

check all the "heavy" components (caps flyback etc.) for broken connections around the solder pads. and the trace leading up to it.

you havent mentioned if the "flicker" you are experiencing is a colored flash, a white flash, black flash, or even just a loss of sync.

It's a loss of sync type of flicker

remove your game board and run a pencil eraser over the contacts, you'd be surprise what a dirty JAMMA can do.
