Hi guys I am making a cmvs with an mv1c board and I have a couple of questions

1. I did the stereo mod but I am getting a buzzing sound from the speakers . how can I fix that problem?

2. The enclosure is made of metal. How can I ground the case because I feel the electricity when I touch the case.

It's possible that both problems are related. Connect the metal case to earth ground.

I have no earth ground I am using a 5v 3a external adapter I was thinking of soldering pin 28 on the jamma harness which is ground to the metal casing. Would that work?

Are you using a jack for your adapter? You could just ground the chassis straight to that as well.

Put up a pic of your setup. It might be easier to help you out then.

sorry for the mess of cables i still haven't finished, the mv1c is on top of a acrylic plate so it's not touching the case.

Well I grounded the case to earth so no more electric shock but I still have the sound buzz. Could it be the start cable? Wich scart cable do you guys suggest? Or could it be the power supply? I am not getting any interference on the video only the audio. What do you guys suggest.
