Preliminary Matters (The Fine Print)

IMPORTANT SAFETY NOTICE

The information in this training manual is intended for use by persons possessing an adequate background in electrical equipment, electronic devices, and mechanical systems. In any attempt to repair a major Product, personal injury and property damage can result. The manufacturer or seller maintains no liability for the interpretation of this information, nor can it assume any liability in conjunction with its use. When servicing this product, under no circumstances should the original design be modified or altered without permission from LG Electronics. Unauthorized modifications will not only void the warranty, but may lead to property damage or user injury. If wires, screws, clips, straps, nuts, or washers used to complete a ground path are removed for service, they must be returned to their original positions and properly fastened.

CAUTION

To avoid personal injury, disconnect the power before servicing this product. If electrical power is required for diagnosis or test purposes, disconnect the power immediately after performing the necessary checks. Also be aware that many household products present a weight hazard. At least two people should be involved in the installation or servicing of such devices. Failure to consider the weight of an product could result in physical injury.

(Electrostatic Static Discharge)

ESD Notice

Today’s sophisticated electronics are electrostatic discharge (ESD) sensitive. ESD can weaken or damage the electronics in a manner that renders them inoperative or reduces the time until their next failure. Connect an ESD wrist strap to a ground connection point or unpainted metal in the product. Alternatively, you can touch your finger repeatedly to a ground connection point or unpainted metal in the product. Before removing a replacement part from its package, touch the anti-static bag to a ground connection point or unpainted metal in the product. Handle the electronic control repackaging a failed electronic control assembly in an anti-static bag, observe these same precautions.

Regulatory Information

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential installation. This equipment generates, uses, and can radiate radio frequency energy, and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna; Increase the separation between the equipment and the receiver; Connect the equipment to an outlet on a different circuit than that to which the receiver is connected; or consult the dealer or an experienced radio/TV technician for help.

Safety and Handling, Checking Points

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.

Basic Troubleshooting Steps

• Define

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. Observation of the front Power LEDs may give some clues.

• Localize

and after giving a thorough examination using your senses the first check should always be the DC Supply Voltages to those circuits under test. Always confirm the supplies are not only the proper level but be sure they are noise free. If the supplies are missing check the resistance for possible short circuits.

• Isolate

Save Energy, Save Money

It reduces the plasma display’s power consumption. The default factory setting complies with the Energy Star requirements and is adjusted to the comfortable level to be viewed at home. (Turns on Intelligent Sensor).

Save Energy, Save Money

Home electronic products use energy when they're off to power features like clock displays and remote controls. Those that have earned the ENERGY STAR use as much as 60% less energy to perform these functions, while providing the same performance at the same price as less-efficient models. Less energy means you pay less on your energy bill. Draws less than 1 Watt in stand by.

X Drive Circuit Board Removal Continued

Make sure AC is removed. Lay the Television down carefully on a padded surface. Make sure to use at least two people for this process so as not to flex the panel glass.

a) Remove the Back Cover. b) Remove the Stand (4 Stand Screws were removed during back removal). c) Disconnect the two connector on the left side of the Main board, P704 and P801. d) Remove the Stand Metal Support Bracket (5 Screws) 2 Plastic tap thread and 3 Metal thread. e) Remove the two Vertical support Braces marked “E”.

Note: There are 4 Screws per/brace, 2 Plastic tap thread and 2 Metal thread. (Note, the right brace has a Grounding wire from the AC input which must also be removed).

f) Remove the 7 screws holding the Heat Sink. (Warning: Never run the set with this heat sink removed).

To remove the heat sink, lift up to release the tacky Chocolate (heat transfer material) and slide the heat sink to the left to clear the connector wires on the right side. Note: There are three large pieces of conductive tape on the heat sink that must be removed. Also, note that there several pieces of Chocolate heat transfer material attached all the way across the underside of the heat sink. There is a mark on either side of the tape on the heat sink which shows its locations.
