Re-Edit screen calibration

Hello everyone!

I have an origional style (non-unibody) 17 inch macbook pro running 10.6.8. Un fortunately it has been having some troubles lately, the screen has been having some troubles, so I calibrated it using the expert settings under the displays system prefrences pannel. I have it set perfectly except it has a blueish hue to it. Its fine, except when im editing videos or photos. I know it has somthing to do with the calibration because when I have it set to an external monitor, the same thing occurs when i have it set to the same calibration. I was wondering if i could go back into the same calibration setting and edit the white point and/or gamma to maybe warm up the screens colors. Thanks in advance!
