My trusty Harris TS44 buttset developed a problem the other day. The 4, 5, and 6 keys have stopped working out of the blue. Has anyone seen this happen before and have a simple solution before I crack open the case to have a look?

If I end up having to open it up, is there any hidden screws? I only see the one just above the battery and the four covered in encapsulation below the battery.
