My galaga i just picked up is having an issue with reds,it shows some red like on the score you can read it but its faint and the legs on the bad guys and the explosions etc,does anyone know which pot is the red adjustment?It has a G07 in it.also how do you adjust the volume? Thanks.

Edit,just checked and its working fine now but it will go off and on like that. any ideas what would cause this?

cold solder joints.

give it a cap kit, fly and re-flow.

and check the video input connector and make sure the pins are still good.

Adjusting volume

The volume pot is on the main pcb... White phillips head surface- mounted type. Slight adjustments go a long way.
