Hey folks, I’m looking for some help with my Filco keyboard. After accidentally spilling a spoons worth of white sugary coffee over it, it is now pressing multiple keys simultaneously when using the worse affected keys, which are F9 to F12, Backspace, Enter and Tilde/Hash, I use a UK layout keyboard, so ISO format and a tenkeyless variant.
Since the incident all the affected keys are multi-pressing, the tilde key seems to be pressing all the following keys in groups, asdf, jkl# and then oddly the number keys from the non existent keypad, 123.
Backspace and a few of the F keys seem to be putting my laptop into standby while also pressing the Page, Home and CapsLock, Windows keys and Control keys, but all affected keys are multi-pressing from all over the keyboard - exactly which keys is hard to ascertain.
Is this keyboard doomed, I cleaned the spill up and flushed out the affected switches with warm water from a straw as well as removing any residue I could see on the bottom PCB side, and left it to dry, to no avail. All other keys work perfectly, except these ones. Could it be a fault with the controller chip, and replacing it might fix it, or is there possible coffee bridging connectors under the backplate that I cannot see?
Would giving the whole thing a distilled water bath possibly help, without the control chip?
Any suggestions or thoughts would be a massive help! My laptop keyboard is truly awful in comparison.
