Plz help me, still learning. I have a Pacman that doesnt show any red. I replaced the chassis with a new one and i still have no red. Whats next? thanks again
You need to test the tube with a rejuvenator. It is a tool that will allow you to see what is happening inside your picture tube as well as clean it if necessary. Where are you located? Maybe someone local will be willing to help.
You can try disconnecting the red, green and blue (keeping ground and sync connected) from the chassis and try plugging the red from the PCB into either the green or blue on the chassis.
Keep in mind it won't show up red, but if you get some kind of picture it would determine that your red on your game PCB is ok.
