it's the PCB that's corroded somehow -like the previous owner spilt a soft drink on it or something?
Soooo, is it possible to check these things using a DMM? 0_o That's all I got.
thanks again,

Also it is worth checking the four ICs 2033 at pin 8, 3 and 12 whether
there is a signal.
If the contacts don't work ever, then maybe also some of the diodes in
the keyboard matrix might have died.
