In just the last couple of months, we have had rather a lot of the flyback
transformers in our 3/50 monitors going bad.  #10 (of 200-odd) gave up the
ghost yesterday afternoon.  While Sun will tell you that the monitor will
have thus-and-so MTBF, they generally seem to have computed those figures
based on the machine being on during office hours only.  Ours are always
on.
