[A6] dead key/switches/aftertouch - advice on fixing/opening

[nemesys 12]

hi guys

my A6 developed a bad contact on b4 key. it doesn't work cept a chance
contact here n there.

altough i did this for some of my synths before, so far i've never opened
A6. i was wondering
if anyone got advice on how to open it (safely), what to look for, and how
to clean the key contact..?

second, some of the micro-switches are having problems too: the soft button
1 and the UP arrow button.
dunno if these can be cleaned, tho my guess is, considering they are modern
microswitches, they
can only be replaced. not sure. anyone had experience ordering spare parts
from Alesis/Numark ?

and finally (jesus..), the aftertouch ain't working for a while now - is
there a ribbon connector
to re-seat or something like that? AT wasnt a show stopper till now, but if
i'm gonna open the beast,
i wanna deal with all quirks at once.


thanks

regards
Tom
