The notebook LCD is too dark, black, all one color, or does not display properly.

Follow this procedure to troubleshoot the notebook LCD.

IMPORTANT:

• If the LCD is all one color or there are large portions which are all one color, tilt open and then close the LCD screen. If the colors change or return to normal as the LCD is moved or lightly tapped, other than the normal changes in brightness as the angle of viewing changes, the video cable has become crimped in the hinge. The notebook will need service to resolve this issue.  Go to Product Repair.
