    • Remove battery cover screw and batteries. Then remove 7 screws from rear. Prise the back and front covers apart using a blunt knife or similar. This requires a bit of force as there are internal plastic clips (one might break but it's not important). The only fragile thing is the glass LCD display.

    • Take care as the two casing halves are attached with two soldered battery wires.They can be positioned so that they are not stretched. (first image)

    • Remove 10 screws from the green printed circuit board to gently detach it (second image). The flexible rubber keypad can now be pulled away for repair.

    • On the back of the rubber keyboard are black conductive discs. The faulty ones can be covered with aluminium foil. (third image).

    • reassembly is reverse of above.

结论

Pasting conductive aluminium foil on the back of these key pads got the battery operated crossword solver working again for near zero cost.

Thanks Andy
