Verify that environmental interference is not the cause of the flickering and discoloration. To do this, try the following suggestions; be sure to look for improvements and changes after following a suggestion:
* Change the location and/or rotate the computer.
* Remove metal objects from the area.
* Look for other environmental influences (power lines, generators, refrigerators, air conditioners).
* Check fluorescent lighting fixtures and transformers, which are also common sources of interference.
If the symptoms you are experiencing do not appear to have an environmental cause, contact an Apple-authorized service provider for additional assistance.
