Re: k5-some keys not working

Hi, the price you paid isn't bad, don't worry. As for the problems,
there are a few problems every K5 owners get at a time or another.

To fix the keys, you'll need to open the synth top cover with the
screws on the left and right side and remove the keyboard (remove
every screws on the bottom that are situated under it) from the case.
The socket for the ribbon cable between the keyboard and one of the
circuit boards is located under the keyboard. The part with the
headphones jack, modulation wheel and pitch wheel will come out with
the keyboard.

Once it's pulled, you'll be able to remove the keys(no tools required,
don't get impatient, if you break a key, it's gone.) and use a Q-tip
with rubbing alcohol to LIGHTLY clean the contacts under the rubber
membrane (do NOT try to clean them too much, it will destroy the
carbon contacts). Sometimes the problem is that the rubber membrane
isn't sitting straight under the key for some reason (watch this while
placing back the keys in the keyboard) and it doesn't work this way.

A cover could help, as there is a bit of "dirt" going under the membrane.

Again, don't use too much alcohol on the contacts, only a slight
cleaning to wipe out things is necessary. The black residue on the
cotton swab is probably going to be carbon coming off. It's OK as long
as you don't remove too much.

Also, don't clean the contacts under keys that work well, it's not
necessary and will not help.

To remove a key, you need push it down (supposing you're holding the
keyboard in a vertical position to remove the keys) while you push out
the snaps with a single finger. It's a bit hard to explain but you
should be able to find out.
