Problem
A single line, small
group of lines, or block
appears on the display
panel. This failure
occurs in only a
section of the display
panel.
Note: When you perform a "self-test" on an external VGA color or monochrome monitor,
the screen should be white. A narrow black border may also appear on the left and right
sides of the display. Either of these displays indicates that the monitor is working
properly.
