Our kids accidentally knocked one of our Panasonic cordless phones (a
KX-TG5632, in case it matters) off the end table and the screen no longer works. I was attempting to open it up and removed all visible screws, but can't get the plastic case open. Has anyone tried opening up one of these recent Pana phones, and if so, where's the hidden latch? Do you think trying to find a tool like
this would help?

Thanks in advance!
