Okay, before everyone panics, the Amperage of the PSU will /not/ fry
your keyboard. If it can't draw enough from the PSU, it will kill the
PSU, if the PSU is rated higher, it will just not be working as hard -
you can't force the current, it has to be drawn.

Incorrect polarity, dead shorts, and other faults such as the wrong
voltage will kill the voltage regulator (which is what I suspect has
failed). Using the correct polarity, correct voltage, and a current
rating equal to or greater than the requirements will be fine.
