  Recall that the colours on the screen result from the combination
of three "cathode rays" inside the tube -- one red, one green, one
blue.  It sounds as if your "red" is not getting the signals it
should, or is misaligned.

  It's probably not the video card.  If you can detach the cable from
the monitor, try a different cable.  It may be that there is a break
or bad contact in the cable itself.

  If that doesn't fix it, see if you can find a place that does
fixed-price monitor repairs.  The place I go to would charge $70 to
fix a monitor this size, assuming that they don't have to actually
replace the tube.
  [You may be tempted to try and fix it yourself.  There are
electronics inside the monitor that can hold thousands of volts even
after it is turned off, and to adjust it you kind of need to be able
to have it on so you can tell what effect you're having.  Paying a
professional makes a lot of sense to me....]
