NSM Jukebox technical tips
Last update

I keep seeing people with keyboard problems on their NSM jukeboxes and it was time to make a page to cover this (and other) issues that are easily taken care of by folks with very basic tools!
To start with if you have this type of "Phone-Pad" keyboard then what follow may help! You have one or more buttons that don't work? Perhaps #1 and #2 or other most often used keys?
Typically the problem is caused by wear of the nubbins that close the spring switch in your keypad - so remove the keypad from the jukebox and set it face down on your work space and then unscrew the back after first writing down the key numbers on the backside! Hold the back on while you remove the last screws otherwise it may spring apart a bit and you then have to hunt around for springs and/or screws...
 
Remove the back and check out the keys that aren't working. Do they look like #1 and #4 here?
 
The easy fix? Lift out the button with the worn nub, separate the button cover from the body and rotate the number 180 degrees, reassemble the button and then simply install it rotated 180 degrees so the unused nub is now going to replace the worn out one!
Put springs back, and replace the back and put it back in the jukebox.
Job done!
If the nubbins are worn out on the other side because someone did this in the past then you have to replace the nubbin with a bit of nylon rod that is the correct diameter to fit in the hole. Click here for the link to the Keyboard 'nubbins'
