The first section will cover Contact Information and Important Safety Precautions
for the Customers Safety as well as the Technician and the Equipment.
Basic Troubleshooting Techniques which can save time and money sometimes
can be overlooked. These techniques will also be presented.
The next section will get the Technician familiar with the Disassembly, Identification
and Layout of the Plasma Display Panel.
At the end of this Section the Technician should be able to Identify the Circuit
Boards and have the ability and knowledge necessary to safely remove and
replace any Circuit Board or Assembly.

Safety and Handling, Checking Points
pgp
Safety & Handling Regulations
1. Approximately 10 minute pre-run time is required before any adjustments are performed.
2. Refer to the Voltage Sticker inside 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.
4. C-MOS circuits are used extensively for processing the Drive Signals and should be protected from static electricity.
5. The PDP Module must be carried by two people. Always carry vertical NOT horizontal.
6. The Plasma television should be transported vertically NOT horizontally.
7. Exercise care when making voltage and waveform checks to prevent costly short circuits from damaging the unit.
8. Be cautious of lost screws and other metal objects to prevent a possible short in the circuitry.
9. New Panels and Frames are much thinner than previous models. Be Careful with flexing these panels. Be careful
with lifting Panels from a horizontal position. Damage to the Frame mounts or panel can occur.
10. New Plasma models have much thinner cabinet assemblies and mounts.
Be extremely careful when moving the set around as damage can occur.
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.
