Pete M Kring IV, try an external display, that way you will know that it is not your video card that cause this. If it is still pink, you have some GPU error, this may require either a fix on the motherboard or even a new motherboard. Loose or damaged ribbon cables are the most likely causes of the pink screen. Check your able for any damage to the insulation, replace it if necessary.Bad CCFL will definitely turn the display pink. you can change the CCFL but a bit of a PITA, you may consider a new LCD.screen. The other possibility is a bad inverter, which is not likely, but possible. Try one thing at a time and see what works for you. The part number for the cable is PM853. This video shows how to change the inverter, you can get the service manual from here which will help you to work on your computer. You can replace the CCFL but for that you will have to know who made our LCD. Check the label on the back of your panel. Hope this helps, good luck. Answer from oldturkey03 on ifixit.com
