I have a II plus keyboard that does not use individual switches. It looks like the top is moulded plastic with shafts on springs and a contact board underneath. I hope that's correct from what I see as I not see individual key switches. I have misbehaving rows of keys (according to the schematics). Some rows don't work and others "bounce" once or twice. I have contacted the person I bought it from, but if the are not helpful I will need to take it apart and check for shorts or misalignments. Can anyone share tips and tricks for this kind of keyboard. It has to be a bigger pain than individual switches since everything must align.
I am also planning on trying an eye dropper with 91% IPL on each keyswitch pushing it 20-30 times before I try to dissemble. I know that helps on the individual keyswitch versions.
Thanks in advance...
