SAFETY PRECAUTIONS

IMPORTANT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts 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

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 th e 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.

Keep wires away from high voltage or high temperature parts.

Before returning the receiver to the customer,

always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, etc., to be sure the set is safe to operate without damage of electrical shock.

Leakage Current Cold Check(Antenna Cold Check)

With the instrument AC plug removed from AC source, connect an electrical jumper across the two AC plug prongs. Place the AC switch in the on position, connect one lead of ohm-meter to the AC plug prongs tied together and touch other ohm-meter lead in turn to each exposed metallic parts such as antenna terminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, the measured resistance should be between 1 MΩ and 5.2 MΩ. When the exposed metal has no return path to the chassis the reading must be infinite. An other abnormality exists that must be corrected before the receiver is returned to the customer.

Leakage Current Hot Check (See below Figure)

Plug the AC cord directly into the AC outlet.

Do not use a line Isolation 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 exp ose d metallic par t. 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.

ADJUSTMENT INSTRUCTION

1. Application Range

This spec. sheet applies to PU41A 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 correct order. But it is

flexible when its factory local problem occurs.

(3) T he 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 100-220

V~, 50/60 Hz.

(5) Before adjustment, execute Heat-Run for 5 minutes.

■ After Receive 10 0% Full white pattern (06CH) then process Heat-run

(or “8. Test pattern” condition of Ez-Adjust status)

■ How to make set white pattern

1) Press Power ON button of Service Remocon

2) Press ADJ button of Service remocon. Select “10. Test

pattern” and, after select “White” using navigation button, and then you can see 100% Full White pattern.

* In this status you can maintain Heat-Run useless any

pattern generator

* Notice: if you maintain one picture over 20 minutes

(Especiall y sharp dis tinction black with white pattern – 13Ch, or Cross hatch pattern – 09Ch) then it can appear image stick near black level.

■ White Balance Adjustment

If you can’t adjust with inner pattern, then you can adjust it using HDMI pattern. You can select option at “Ez-Adjust Menu – 7. White Balance” there items “NONE, INNER, HDMI”. It is normally setting at inner basically. If you can’t adjust using inner pattern you can select HDMI item, and you can adjust.

In manual Adjust case, if you press ADJ button of service remocon, and enter “Ez-Adjust Menu – 7. White Balance”, then automatically inner pattern operates. (In case of “Inner” originally “Test-Pattern. On” will be selected in The “Test-Pattern. On/Off”.

● Connect all cables and equipments like Pic.5)

● Set Baud Rate of RS-232C to 115200. It may set 115200 orignally.

● Connect RS-232C cable to set

● Connect HDMI cable to set

- Press “Power only key” of service remocon and operate automatically adjustment.

- Set BaudRate to 115200.

● You must start “wb 00 00” and finish it “wb 00 ff”.

● If it needs, then adjustment “Offset”.

■ 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 High Light adjustment.

- All of the three mode

Let R-Gain to 192 and R, G, B-Cut to 64 and then control

G, B gain adjustment High Light adjustment.

- With volume button (+/-) you can adjust.

- After all adjustment finished, with Enter (■ key) turn to

Ez-Adjust mode. Then with ADJ button, exit from adjustment mode
