so i got a 922 i listen to quite a bit and the other day i realized that my am and short wave buttons don't stay depressed when i push them, the fm works without a problem and i was wondering if anyone here had any suggestions as to what would cause this problem and how to fix it, and out of pure curiosity, a suggestion as to what may have caused this. Ive had this box for a bout 4 years now and these switches worked when i got it, so im confused as to how they just stop working.
