There are new membranes available for the sx-64!
(cleaning the keyboard will solve issues only for a while is my experience)

In reply to Chris. Also to add.. if you didn't remove the keys then you didn't take it completely apart to clean. The layers underneath them have to be pulled apart to be cleaned.

I have cleaned 2 SX-64 keyboards for keys either not working or having to press them really hard to work. Stripping the keyboard completely down and cleaning the pads has fixed it on both and both work 100% now. This solution you posted is not a good one because you had to cut the cable to make it fit (damaging the cable) when all you had to to was take it completely apart and clean. There are guides on the internet for how to properly clean the keyboard when keys aren’t working right.

In reply to Siana. Well, the good news is that there are plenty of aftermarket cables available.

And now you have damaged an exceptionally rare cable. I know it’s not fatal, but removing the metal shield off the adapter’s connector might have been better and easier. Depends, but often it’s only attached at the ears rather than in the middle of the connector, so you might have even had a lot less plastic to snip through.

In reply to Kevin. Good to hear. I have one of my keyboards on my desk waiting for some time for me to try and clean it.

I also had exactly the same symptoms and took my keyboard apart and cleaned with alcohol. It also works like new now. You have to actually take the rubber membrane (carefully) off the circuit board and clean every contact with alcohol, on both the membrane and the board. It takes time, but you will have keyboards like new again.

In reply to Fred. Yes, I'll try that next. However, I'm not sure how simple the solution is as that is fraught with its own issues. I did already do a cleaning on both keyboards, although not all the way stripped. I think there's some issues with the contacts at this point.

This looks to me as a poor solution for a simple problem. I had exactly the same symptoms with my keyboard so i took it apart and carefully cleaned it with alcohol. There are many “how to” instructions to see on the internet, just google “cleaning keyboard sx-64”. My keyboard is working perfectly again.
