Mario bros. arcade issue

Question from Brian: Hello,

Was wondering if you could lead me in a direction to stop my screen rolling on my Mario bros. arcade cab. The hold adjustment just doesn’t completely stop the rolling before it starts going the other direction. Any help would be awesome.

That’s my main concern. I do have one other issue with it if you have the time to answer. Volume adjust goes from really loud to you can barely hear it. No in between or medium.

Thanks, Brian C. from Columbus, GA.

Response from Jonathan: Brian,

Sounds like you need to replace the potentiometers for both your hold and volume adjustments. The hold adjustment could probably be replaced with the exact same pot but the volume will probably need to be replaced with a pot that has a lower value. Here’s a good article about arcade games and volume you might check out: http://scarvell.net/wiki/index.php?title=VOLUME_CONTROL_MOUNTING_AND_WIRING.

Hope that helps. Thank you for your question and good luck with your repair.
