Visually Inspecting Your System
Improperly set controls and loose or improperly connected cables are common causes of problems with hardware components. When investigating a system problem, first check all the external switches, controls, and cable connections. If this does not resolve your problem, then visually inspect the system's interior hardware for problems such as a loose card, cable connector, or mounting screw. Refer to Visual System Inspection for instructions about how to verify that your hardware components are properly installed.
