The Sony Trinitron monitors always degauss on power-up.  Sometimes you can 
hear it, sometimes not.  Actually, if you turn it off and back on
again, it won't degauss -- there's a "positor" in the circuit that
gets hot and cuts the coil current.  It has too cool down for the coils
to energize on power-up.

So don't worry, your monitor's probably fine.
