Guidelines
1. Perform the user troubleshooting procedures.
2. Perform a visual inspection of the system.
3. Look for obvious causes of the malfunction first, such as loose connections,
broken wires, or discolored/burned components.
4. If a single function is not working, concentrate on that circuit or that part of
the system.
5. If several symptoms are present, locate a circuit that is common to all affected
functions. If the solution is not obvious, check the power supply circuits first.
