SOLVED - A600 keyboard domes connectivity issues, any way to revitalize them?

[keropi]

Hiya!

I have an excellent looking A600 keyboard but it gives me the classic key pressing issue: several do not register and some you need to press really hard to register
naturally I got a replacement new membrane for it but sadly this did not help with the issue much
so I got a few replacement key domes (used as expected so they probably had their own varying levels of wear and tear) and managed to fix some keys with them - but not all

since this is really a very nice looking keyboard, is there a way to save it?
is there any place that sells new domes as well? or perhaps some trick to them?
any help you be appreciated, thanks!

well... apparently this was an alignment issue - the membrane was not exactly in the position it should be
I have no idea why but I re-did it and it got fixed , I was clued to it because I was testing with a dome the membrane pads and all registered just fine - even with a dome that was not registering before...
maybe this thread can be a reminder for future people with the same issue - check if the membrane is in the correct position

If you still have an issue. The. A plain piece of paper can be used to be rubbed on the domes to help clean them up.
