General Troubleshooting 

Troubleshooting is the process of locating or isolating system 

discrepancies or faults and determining corrective action that may be 
required. 

There are some general procedures that can isolate and resolve many 

common fault situations.  If a fault is reported or observed, perform 
these steps first. 
1.

 

Ensure that all cables and power cords are firmly connected. 

2.

 

Ensure the component power source is applied. 

3.

 

Ensure the component is turned on. 

4.

 

Restart the component. 

5.

 

If there is still a problem, use the flowcharts below to help 

determine the solution. 

6.6 

Equipment Troubleshooting 

If the fault is present after performing general troubleshooting 
procedures, refer to Table 6-3.  Find the symptom and follow the 

procedures detailed in the referenced flowchart until a system fault is 
isolated and corrective action restores the system to full operation.
