We have 3 1186's, all about two years old, none of them on
maintenance.  On all three, the monitor screens are becoming very
fuzzy and out of focus, so much so that the machines are becoming
unusable.  Strangely, immediately after leaving 'Idle' mode
in the morning when starting work, the image is reasonably clear,
but it quite quickly gets worse (in about 5 minutes) and then
stays bad.

Xerox's "cure" is to replace the monitor unit, at a cost of about
US$3000 each.

Is this problem a common one?  Can we cure it?  We would be prepared
to change the tube if they are available and that is what is required.
