There were some postings a few months back about premature failures
with Wyse 60 terminals.  Most of the 15-20 of them that we bought
have died now.  I've found that many of them have bad flybacks, and
have fixed a couple by replacing them.  The remaining ones have
a mysterious power-supply suicide mode, in which Q-102 shorts itself
out. Replacing Q-102 is no help, it just shorts again.

Did anyone ever find out what the real problem with the boards are?
Replacing the entire board seems extreme.  Just trying to get
a service manual from Wyse is like passing through 7 levels of hell.
