Regarding the repair of Sun console keyboards which have keys that
do not work, the following types of helpful suggestions were
1.) Cleaning under the keys with compressed air blown in
from above the keyboard.
2.) Removing the back of the keyboard and cleaning the contacts
with a solvent (isopropyl alchohol, distilled water,
electronic parts cleaner) or even with more compressed
3.) Trying the above cleaning by just prying off the keycap with
a pocket knife, or preferably, two bent paper clips.
4.) Closer inspection might reveal broken leads to the key. If so,
these can be found with a magnifying glass and/or ohmeter.
The leads can then be re-soldered together.
5.) In some cases, there is a hardware problem with the key. This
can be the "plunger" or a small plastic U shaped part which
can break or come loose. Inspect working keys by removing the
key cap as described above. Then repair the broken key by
comparing to a working key and, if necessary, swapping out
the plastic U part with a less needed key.
Most responses say that their method almost always works. Thanks to
