Do you have a full (rectangular) raster?  Or is it squeezed in around any
of the edges?  This could indicate a bad power supply in the monitor.
If it is squeezed in AND wavy, this could indicate a bad filter capacitor
in the power supply.  Also, check around the vicinity for other sources
of low frequency magnetic fields (motors, other monitors, soldering irons).
If the monitor is changing colors during the waviness, it could mean your
built-in degaussing coil is activating for too long a time period.  These
are designed to activate for only a brief time during power-on.
