Troubleshooting General/ - 1

General

The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts in the order of most likely solution, try
the first cure first. Verify whether or not the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(Note: If you have replaced a module, reinstall the original module
before you proceed to the next cure.)

If you are not sure what the problem is, or if the Symptom Charts
do not resolve the problem, refer to the Flowchart for the product
family.

For additional assistance, contact Apple Technical Support.

Troubleshooting Symptom Charts/Video - 16

Video

Pixel is always white
or always black

PowerBook 180c: In general, no display should be replaced
because of subpixel irregularities. If the number of
irregularities on a display appears excessive, contact Apple for
more information.

Note: Each pixel on an active-matrix color display consists of
three subpixels (red, green, and blue). In turn, each subpixel
has a transistor that controls light transmission. A PowerBook
180c display, therefore, contains a total of 921,000 transistors
(640 x 480 x 3). Due to technology constraints, subpixel
transistor irregularities (red, green, blue, black, and white) are
allowed in this display.

PowerBook 165c: replace display.
