Title: MS Pacman - have sound, no picture
Post by: PhillyNJ on March 20, 2014, 01:27:48 pm
Hi,

I have a Ms Pacman original arcade machine. I can hear sound, but I am not getting a picture. How can I confirm that the monitor is shot and not a bad connection or the PCB?

What are the possible causes?

Thanks for the help.

Phil

First thing I do is make sure the monitor is getting proper power from the transformer. Use your meter and check to make sure it's getting around 115-120VAC. If it is and you see neck glow and hear the monitor fire, chances are its a connection issue or something on the chassis.

If its not getting the correct voltage, check your fuses and the measure voltage directly from the transformer if the fuses are all okay.
