Hello,
I've had this keyboard a little over a year and last night the b and n keys quit working. They are completely non functional. In addition, it appears as if the control key is always pressed.
Using google + this forum I've learned this could be a switch problem or a logic board problem? I'm not entirely familiar with the logic board, but if I had to guess I think it's the 3x1" pcb towards the top right of the keyboard?
At any rate, I've taken the keyboard apart and I've used a multimeter to poke around and test for continuity on the suspect keys, but I'm not sure what I'm really looking for to diagnose and fix this issue. I've also got a soldering iron at my work bench if needed.
What should I be doing to fix this keyboard? Thanks!

Try using Aquakeytest

pull off controller board, check the contacts that goes to the chip itself..

Thanks for the reply. The individual switches test fine and when I close the switch and run the hook the multimeter between each key and the pin that drives it on the controller, it looks good. Does this indicate a problem with the controller itself?

Test the diodes.
