Answer to: Are there any repair kits available? my keyboard doesn't workThe problem lies with the ribbon cable between the keypad and display. It either works loose or corrodes slightly. Non invasive solution: Press the front hard between the 2 leftmost function keys at the top of the keypad while using the keypad. It's really awkward but it works. Invasive solution: This involves sliding a blunt flat tool (spatula?) into the side join of the case by feel and then using a thin knife to locate and cut the plastic pillars in the middle of the case. I am sorry this is not very detailed but I decided not to risk it myself and have since lost the link to the site that gave instructions. I hope knowing it is out there will help you to search and find it.
