Important: The PowerBook family includes four displays—an active matrix and three FSTN displays. Each of these displays requires a compatible inverter and display cable; the inverters, display cables, and displays are not interchangeable. Before ordering a replacement display, display cable, or inverter, refer to the display matrix.

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.
