Hi!
I got new keyboard and it is pretty good working except single key - CONTROL. This key needs hard or any extra hitting to make keypress event. Successful keypress is rare.
I was looking below key and all key components are ok. Can anybody help me how to get problem source and fix it?
Thank you for all. Miro

Thank you for suggestion.
I will use technical alcohol.

There are like a million screws. Clean the whole keyboard while you have it open!!!
I had to clean both my 128 and PET keyboards, they went from unresponsive rubbish to pretty much working perfectly.

I know that there is lot of screws and my keyboard works perfectly - I need only fix this key, nothing more.
I do it later, when I get time of my C128.

I had a similar problem, the key had no conductivity acros the little black strip on the bottom of the socket. Normal range is 100-1000 ohms. You have to take the keyboard apart to fix it, lots of little screws and some unsoldering but not too bad, really. You can replace the the plunger assy from another key. You can also just replace the little black conductor by unpeeling the old one and replacing it with a good one from a spare key. I know, I don’t have any spare keys either but used the F7 key temporarily. I dont use it much anyway.
I saw a good YouTube video where the guy did this very thing and now I have too.
