it was purchased outside of US and the warranty expired in 2011.

I'm more curious in knowing why simply removing the keyboard could have damaged it?

> you surely tried to reseat the ribbon cable that connects the keyboard to the mainboard ?

> the wiring inside the keyboard is quite sensitive - you might have inadvertently damaged it by using to much air pressure.

  If one "wire" is damaged usually a whole bunch of keys fail.

> make sure the connector on the mainboard is not damaged and that the tiny sliders at both ends of it

  (if  there are any) are properly in place.

Hi 1B1N8htsRT3GnkpBu,

Keyboard has a delicate connector it could have been damaged while reconnecting.
