Troubleshooting
Use the information in this chapter to diagnose and correct monitor problems. This
chapter describes how to troubleshoot a monitor that is not operating correctly. To
perform any recommended repairs, see Chapter 4, “Repairing the Monitor.”
Overview
You can repair the monitor in either of two ways:
• Return the monitor to a Philips authorized service center for repair.
• Purchase spare parts from a Philips authorized service center.
Caution Repairs should be made by qualified service personnel only.
Repairs should be made only with the recommended parts. Use of incorrect parts
can cause damage to the monitor or incorrect measurements.
The tools required to repair the monitor are listed in “Tools Required for Service” on
page 4-3. If you open the case for a repair, you then must perform specific tests after
reassembly. For detailed information about these tests, see Chapter 2, “Performance
Verification Testing.”
The Philips Parts Center stocks board level assemblies and mechanical parts.
Chapter 5, “Replacement Parts and Assembly Drawings” lists these parts and
assemblies. Service notes announce the availability of additional spare parts.
When You Cannot Correct a Problem
The information in this chapter is intended to help you resolve most problems that
may occur with your monitor. If you still cannot isolate a problem after using the
information in this chapter, call the Philips Customer Care Center or your local
representative.
Note — If you have created a custom password for your institution, you must change
the password to the Philips default (215) before you return the monitor for any
reason.
