Safety & Handling Regulations
1. Approximately 10 minute pre-run time is required before any adjustments are performed.
2. Refer to the Voltage Sticker on the Panel when making adjustments on the Power Supply, Y-SUS and Z-SUS Boards.
3. Always adjust to the specified voltage level (+/- ½ volt) unless otherwise specified.
4. Be cautious of electric shock from the PDP module since the PDP module uses high voltage, check that the Power Supply
and Drive Circuits are completely discharged because of residual current stored before Circuit Board removal.
5. C-MOS circuits are used extensively for processing the Drive Signals and should be protected from static electricity.
6. The PDP Module must be carried by two people. Always carry vertical NOT horizontal.
7. The Plasma television should be transported vertically NOT horizontally.
8. Exercise care when making voltage and waveform checks to prevent costly short circuits from damaging the unit.
9. Be cautious of lost screws and other metal objects to prevent a possible short in the circuitry.
10. New Plasma Models have thinner Display Panels and Frames than previous models. Be careful when lifting
Plasma Display's because flexing the panel may damage the frame mounts or panel.
Checking Points to be Considered
1. Check the appearance of the Replacement Panel and Circuit Boards for both physical damage and part number accuracy.
2. Check the model label. Verify model names and board model matches.
3. Check details of defective condition and history. Example: Y-SUS or Y-Drive Board Failure, Mal-discharge on screen, etc.
