Hello !

I have this PcPartner motherboard which POST without any problem except the keyboard doesn't work ...
I can see the LEDs flashing so the fuse is good and the keyboard is properly powered. I sprayed contact cleaner in the kB connector just in case, but it didn't work ...

What should I consider next to try to fix it ? I am out of ideas ... Do you see any flaws on the PCB ?
