Dark Bands Showing Intermittently for MacBook Pro

This blog post is to capture a support article which helped me fix a problem on my MacBook Pro. Google still brings it up as the first result, but Apple seems to “misplace” the page when I visit it. The page in question was live at the time of this post, but I’m going to capture the relevant information here in case Apple misplaces the page again.

You may see multiple, dark vertical bands or dark bumps starting along the bottom of the MacBook Pro (15-inch, Early 2008) or MacBook Pro (17-inch, Early 2008) with the high resolution LED backlit display, as shown below.


To help prevent this from occurring, download and install Mac OS X v10.5.3 or later from Apple Downloads.

If the issue persists when running Mac OS X v10.5.3 or later, a quick reset of the display panel will reset the LED backlights.

The quickest way to reset the display is to use the following key combination:

  • Press Control - Shift - Eject.
  • After the display goes to sleep, wake it by pressing any key on the keyboard.
