HP 48GX, weird on key behavior -- only works when simultaneously pressing a white key

Hi all,

  I have an hp48gx calculator that I love, but, the "on" button no longer gets recognized as being pressed unless one of the top row buttons is pressed at the same time (e.g., the white "C").

example:  to turn off, I need to do rshift, then hold on and press "C".  expected behavior: rshift, on should turn the calculator off.

example: to turn up contrast, I have to hold C-On and press .  expected:  on and press plus

Any thoughts?

 

Thanks

 Jonathan
