Maarten, start off by trying what Apple suggest:"LCD Display is tinted another color.
Reset the parameter RAM.
- While the computer is off, with your left hand, hold down the Apple key, the option key next to it, and the letter R. When you have them all pressed push the power button with your right hand and then quickly move that hand to hold down the letter P. Keep the four keys pressed while the computer starts up.
- Make sure you hold down the four keys (P-R-Command-Option) while the computer starts up. When you keep all the keys held down, you will hear the startup chime over and over again (about every ten seconds) until you let go. After you hear the second chime, you can let go of the keys.
- If you didn’t hear at least two startup chimes, repeat the procedure above and try again. It’s important that you hear two startup chimes when performing this procedure. This indicates that you have successfully reset the computer’s PRAM (Parameter RAM).

No: Continue to the next step.

Yes: Replace the LCD display panel.
