TROUBLESHOOTING
5.1 General Rules
- Learn about the problem.
Talk to the operator who is using the equipment and probably knows more about the
problem than anyone else.
- Examine the environment.
Could it cause problems for the equipment?
For example, is it very dirty or very hot?
- Identify the problem.
Before removing any FRUs, demonstrate the fault to yourself.
The LA 310 printout will show many of the problems.
- Isolate the problem.
Use the faultfinding notes and tables and any other assistance to help you.
Also check the initial power-up sequence as detailed in Section 3.1.
- Correct the problem.
Use replacement and adjustment procedures to bring the equipment back to full
service.
- Test the equipment.
Wherever possible test the equipment in the presence of the operator to show that
the problem has been fixed and that no other problems have been introduced.
