Hello everyone.

I have IBM KB-8926 keyboard (https://i.imgur.com/mqF1mns.jpg), it was dirty and followed this guide to clean.

Now, when I press w, "we" appears, same goes for 2, 3, x, s, d, c - neighbouring buttons. Just that side, though.

I only washed the buttons and dried them, never touched the board, membrane, conductive trace parts.

Thinking the buttons are still wet, I've checked everything, each part of the keyboard and didn't find any water somewhere.

I tried to remove the buttons and test the keyboard by the touching the plastic membrane, still the same. See the picture please.

I really hope I didn't kill this keyboard, it's not that much money, not a mechanic one, but I really liked the typing on it. 🙁

What am I missing here? Any clue would be much appreciated.

EDIT: And even removing the plastic membrane, directly touching the main conductive trace surface (the surface showing in the 3rd picture) leads multiple button pressures as well, with keys; 2, 3, w, s, d, x, c
