Numark Omni repairing

[mistertuckshop]

Anyone got any experience in this? Basically, one of the buttons on my Omni (pitch bend, which I use to turn FX bank 1 or 2 on or off on deck A... or C ) doesn't respond as well as it should - I really need to push it quite hard for it to work. I thought this was a bit weird because the buttons are 'clicky' rather than spongy, so I wouldn't have thought pressing it harder would make any difference, but it does...
I'm tempted to take it apart, but terrified of breaking it, because I don't really want to have to go and buy a new one...

Well, seeing as I can't even figure out where to begin taking it apart, don't think I'm going to get very far... oh well, looks like I'll just have to hit that button harder. Until I can buy a vci-100se, anyway...
