5.1 Troubleshooting Guidelines
5.1.1 Identify the problem
Due to the wide variety of potential symptoms, certain problems may be more subtle than others.
Following the guidelines of the tests will help determine the problem, if one exists.
5.1.2 Avoid shorting component leads together
During repair procedures, it can be tempting to make a quick series of measurements. Always turn
the power off before connecting and disconnecting the test leads and probes. The accidental
shorting of leads can easily stress the components and cause a second failure (aside from the safety
risk).
5.1.3 Use the proper equipment
During repair procedures, the following tools may be required:
• Metric Allen wrench es (2.5, 3, 4, 5, 8 mm)
• Phillips screwdriver (#1 and #2)
• Diagonal pliers
•Flathead screwdriver
• Metric M3 and M4 socket screwdriver
• Adjustable wrench
• Tweezers
• Krytox Lubricant (P/N:0510-00-0020)
It is imperative to use the designated equipment in order to ensure proper results of any and all test
procedures.
5.1.4 Clean up the repair area
After any repair, clean off the repair area.
