MONITOR HAS PINK HUE ON SCREEN

Hi,
I have a monitor on a customers system that has a pink hue. when you boot the system you can see clearly with the start scren that it is pink. the letters that typically whit are pink. I have degaussed it several times and reloaded the drivers for the video card. It has the same pink hue on a different system as well. Has anyone experienced this.
Thanks
