SAFETY PRECAUTIONS IMPORTANT SAFETY NOTICE Many electrical electrical and mechanical mechanical parts in this chassis have special special safety-related safety-related characteristics. These parts are are identified by in the Schematic Diagram and Exploded View. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.

General Guidance

Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet.

 An isolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation. If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with the specified. When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1 W), keep the resistor 10 mm away from PCB.

Do not use a line Isolation Transformer Transformer during this check. Connect 1.5 K / 10 watt resistor in parallel with a 0.15 uF capacitor  between a known good earth ground (Water Pipe, Conduit, etc.) and the exposed metallic parts. Measure the AC voltage across the resistor using AC voltmeter  with 1000 ohms/volt or more sensitivity. Reverse plug the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS which is corresponds to 0.5 mA. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.

Leakage Current Hot Check circuit Keep wires away from high voltage or high temperature parts.

 AC Volt-meter  Before returning the receiver to the customer,

SPECIFICATION NOTE : Specifications and others are subject to change without notice for improvement.

1. Application range This spec sheet is applied all of the PDP TV with PB23A chassis.

2. Requirement for Test Each part is tested as below without special appointment. (1) Temperature: 25 °C ± 5 °C(77 °F ± 9 °F), CST: 40 °C ± 5 °C (2) Relative Humidity: 65 % ± 10 % (3) Power Voltage : Standard input voltage (AC 100-240 V~, 50/60 Hz) * Standard Voltage of each products is marked by models. (4) Specification and performance of each parts are followed each drawing and specification by part number in accordance with BOM. (5) The receiver must be operated for about 5 minutes prior to the adjustment.

3. Test method (1) Performance: LGE TV test method followed (2) Demanded other specification - Safety : CE, IEC specification - EMC : CE, IEC

ADJUSTMENT INSTRUCTION 1. Application Range This spec. sheet applies to PB23A chassis applied PDP TV all models manufactured in TV factory.

2. Specification (1) Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument. (2) Adjustment must be done in the correc t order. But it is flexible when its factory local problem occurs. (3) The adjustment must be performed in the circumstance of  25 °C ± 5 °C of temperature and 65 % ± 10 % of relative humidity if there is no specific designation. (4) The input voltage of the receiver must keep AC 100-240 V~, 50/60 Hz. (5) Before adjustment, execute Heat-Run for 5 minutes.

■ White Balance Adjustment (Manual adjustment) ● Test Equipment: CA-210 - Using PDP color temperature, Color Analyzer (CA-210) must use CH 10, which Matrix compensated (White, Red, Green, Blue compensation) with CS-2100. See the Coordination bellowed one. ● Manual adjustment sequence is like bellowed one. - Turn to “Ez-Adjust” mode with press ADJ button of service remocon. - Select “10.Test Pattern” with CH+/- button and press enter. Then set will go on Heat-run mode. Over 30 minutes set let on Heat-run mode. - Let CA-210 to zero calibration and must has gap more 10cm from center of PDP module when adjustment. - Press “ADJ” button of service remocon and select “7.White-Balance” in “Ez-Adjust” then press “ ►” button of  navigation key. (When press “ ►” button then set will go to full white mode) - Adjust at three mode (Cool, Medium, Warm) - If “cool” mode Let B-Gain to 192 and R, G, B-Cut to 64 and then control R, G gain adjustment High Light adjustment. - If “Medium” and “Warm” mode Let R-Gain to 192 and R, G, B-Cut to 64 and then control G, B gain adjustment

6. GND and ESD Testing ● When tester will measure on Cool condition, adjust W30 on TV display menu.

6.1. Prepare GND and ESD Testing. ■ Check the connection between set and power cord
