Sounds like the green pot needs adjusted on the monitor, if that doesn't work..the monitor may need a little work
 
Oooo. Just green... If you have filter board, remove it. If nothing works in it, Replace the fuses and check to make sure the pins on the connector aren't bent up.
 
the fuse holders weaken over time and dont grip the fuse tight enough to allow proper electron flow

then i would suggest to ever so slightly wiggle the connector where it attaches to the game board PCB. ever so slightly

the pins inside the connector can also weaken over time and not allow proper electron flow. wiggling the connector can sometimes make the pins connect to the PCB and the game works like it should. if that's the case then the connector and the pins need replacing

sometimes the diodes on the PCB can go bad as the AC is chopped up there on the board and made into voltages that the game needs to operate
 
I'm still having problems with my Ms. Pac

CONSTANTLY resetting...

Randomly.....

Has the 96-1 kit installed.

Seems to be VERY sensitive to "touch" .... guess "static" ???

Checked power cord AND "ground" lead is installed.....

But it won't last more than 2-3 minutes without a reset

:(

Looking for help

Many thanks

Rob
