My monitor is yellow tft

[blawblaw]

Right, so I left my monitor on overnight by accident (screensaver's been turned off) and I wake up to find that the screen has a really yellow hue to it. I figured that that makes sense so I turn off my monitor for the day and here I am now.

It starts off normal, then after about 10-15 minutes it gets all green and yellow again. Please tell me that I don't need a new monitor

It sounds to me like the blue channel is giving trouble, the first thing I would check is the cable. If that doesn't fix the problem I would try a different computer, otherwise it would appear to be the monitor.
