 |  Re: Keyboard Failure
Have you ruled out the keyboard itself? Have you measure the resistance across the pins on the cable when pressing a key? It should be around 150 ohms and anything higher than about 800 ohms will give you problems. I've had KB's in the past whic have been kept in damp conditions where none of the keys made sufficient contact to work.
Have a look at my video here. https://www.youtube.com/watch?v=0iJZgKRIRsQ
At about the 5 minute mark I talk about measuring the KB resistance.
