just picked up a pacman cocktail with a dead monitor for free. replaced monitor. game plays great but total hummed static with speaker, you can hear the game playing.

not sure what to check for. doesn't look like anything wrong with wires. replaced with another speaker and still same thing.

also the light bulbs for the control panels and coin light are not working. put all brand new ones in.??? maybe something common between the two. any help would be great..
 
It COULD be related. I would guess a bad connection in one of your molex connectors?
Are you getting 5Vac to the bulb socket? Pull out your volt meter and test.......
 
Wow, a pac cocktail for free! Excellent score.
I would start by checking the edge connector, make sure its clean. Next suspect would be the 330uf cap on the mainboard.
As far as the lights, ohm out the bulbs and see if they are good. The cocktails have a seperate fuse to power those lights, check that fuse out.
