SAFETY PRECAUTIONS

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 X-RADIATION, 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 the circuitry that may be inadvertently introduced during the service operation.

If any fuse (or Fusible Resistor) in this monitor is blown, replace it with the specified.

When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB.

Keep wires away from high voltage or high temperature parts.

Due to high vacuum and large surface area of picture tube, extreme care should be used in handling the Picture Tube. Do not lift the Picture tube by it's Neck.

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 1MΩ and 5.2MΩ. 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 1.5K/10watt resistor in parallel with a 0.15uF 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 0.5mA. 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.

(4) White Balance Adjustment (Manual adjustment)

1) 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.

2) 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 “

G” button

of navigation key. (When press “

G” 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

6. Test of RS-232C control.

- Press In-Start button of Service Remocon then set the “4.Baud Rate” to 115200. Then check RS-232C control and

7. Selection of Country option.

- Selection of country option is allowed only North American model (Not allowed Korean model). It is selection of Country about Rating and Time Zone.

(1) Models: All models which PB82C Chassis (See the first

page.)

(2) Press “In-Start” button of Service Remocon, then enter the

“Option” Menu with “PIP CH-“ Button

(3) Select one of these three (USA, CANADA, MEXICO)

defends on its market using “Vol. +/-“button.

Caution : Don’t push The INSTOP KEY after completing the

function inspection

Caution : Inspection only PAL M / NTSC

8. GND and ESD Testing

8-1. Prepare GND and ESD Testing.

- Check the connection between set and power cord

8-2. Operate GND and ESD auto-test.

(1) Fully connected (Between set and power cord) set enter

the Auto-test sequence. (2) Connect D-Jack AV jack test equipment. (3) Turn on Auto-controller(GWS103-4) (4) Start Auto GND test. (5) If its result is NG, then notice with buzzer. (6) If its result is OK, then automatically it turns to ESD Test. (7) Operate ESD test (8) If its result is NG, then notice with buzzer. (9) If its result is OK, then process next steps. Notice it with

Good lamp and STOPER Down.

8-3. Check Items.

(1) Test Voltage

GND: 1.5KV/min at 100mA

Signal: 3KV/min at 100mA (2) Test time: just 1 second. (3) Test point
