All of the terminals that we have, except for the system consoles are
Wyse 60s.  We have had several fail, and if they are not in warranty,
then it can cost a whopping $128.00 to get it fixed.  We finally
talked to a service manager at Wyse Tech. and we were informed that a
part (I believe the flyback transformer) has a rated life of approx.
14000 hours.  Thus after a little more than a year of continuous 
operation, one could expect the terminal to stop working.  He suggested
that when possible, the users should turn their terminal off at the end
of a day.  This would effectively extend the life of the terminal to over
two years.
