Symptoms: Keys 1 and + do not function.
Solution: + key works after some repeated pressing, no such luck with the 1. Keyboard is a membrane type with double action plunger to limit the force on the membrane contact. Disassembly gives access to the membrane but not the actual contact area. 1 pad worked some with finger force. Functional.
