Does anyone have experience with fixing hawks? I picked one up from a friend and the thing doesn't work. It looks like the 3.5mm plug is broken. you can move it pretty easily with your finger. the machine is still under warranty so I could send it back but if the 3.5mm plug is easy enough to replace I'd rather do that...I just don't want to start tearing this thing apart and void the warranty only to find out I can't replace the plug myself...
