  • Page 3 PLASMA Overview Troubleshooting Safety Rules Safety & Handling Regulations 1. Approximately 10 minute pre-run time is required before adjustment. 2. Do not exceed Higher voltage than is required for the product. 3. Be cautious of electric shock from the PDP module since the PDP module uses high voltage, and it is recommended that you should not touch the drive circuits for at least one minute because of residual current stored.
  • Page 4 Switch Mode Power Supply Troubleshooting This Section of the Presentation will cover troubleshooting the Switch Mode Power Supply for the Single Scan Plasma. Upon completion of the section the technician will have a better understanding of the operation of the Power Supply circuit and will be able to locate voltage and test points needed for troubleshooting and alignments.

    Troubleshooting Steps • Define Look at the symptom carefully and determine what circuits could be causing the failure. Use your senses Sight, Smell, Touch and Hearing. Look for burned parts and check for possible overheated components. Capacitors will sometimes leak dielectric material and give off a distinct odor. Frequency of power supplies will change with the load, or listen for relay closing etc.
