That's the degaussing cable - what removes stray magnetism from the
monitor on power-up/pressing of a 'degauss' button.
If physically unplugging the degaussing coil (which is the loop of wire
around the front of the monitor) fixes the color issue I would suspect that
the degaussing switch circuit has become leaky and is leaving the coil
partially energized all the time. The coil sees power for a short period
when the monitor is first powered up or the user calls for a 'degaussing'
from the monitor controls. Under normal use the coil
should not be
energized.
