Chapter 5 - Troubleshooting
The flow chart of Figure 5 shows a sequence of actions and decisions you can use
after the initial diagnosis of a "total failure" as a power supply or display
problem.
Note—If the apparent "total failure" is caused by a malfunctioning display
backlight, you may see a faintly lit display with the appropriate Power-On
Self Test message. The troubleshooting under these circumstances is
described in this section.
