This is more directly applicable to electronic equipment, but the Navy teaches a six-step troubleshooting process:

  1. Symptom recognition.

What's the equipment doing? What should it be doing?

  1. Symptom elaboration.

What else is going wrong, beyond what the user initially reported?

  1. Listing probable faulty functions.

Of all the building blocks in this complex system, which ones could be causing the problem?

  1. Localizing the faulty function.

Which building blocks are actually causing the problem, and which ones are working OK?

  1. Localizing trouble to the circuit.

Drill down as far as possible to isolate the problem.

  1. Failure analysis.

Figure out why that component failed (including root causes), fix the problem, and test the repair you made.
