SAFETY PRECAUTIONS

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by inthe 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 toprevent 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 theservicing of a receiver whose chassis is not isolated from the ACpower line. Use a transformer of adequate power rating as thisprotects the technician from accidents resulting in personal injuryfrom electrical shocks.

It will also protect the receiver and it's components from beingdamaged by accidental shorts of the circuitry that may beinadvertently introduced during the service operation.

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

When replacing a high wattage resistor (Oxide Metal FilmResistor, 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, connectan electrical jumper across the two AC plug prongs. Place theAC switch in the on position, connect one lead of ohm-meter tothe AC plug prongs tied together and touch other ohm-meterlead in turn to each exposed metallic parts such as antennaterminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, themeasured resistance should be between 1MΩ and 5.2MΩ. When the exposed metal has no return path to the chassis thereading must be infinite.An other abnormality exists that must be corrected before thereceiver 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 capacitorbetween a known good earth ground (Water Pipe, Conduit, etc.)and the exposed metallic parts.Measure the AC voltage across the resistor using AC voltmeterwith 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat ACvoltage measurements for each exposed metallic part. Anyvoltage measured must not exceed 0.75 volt RMS which iscorresponds to 0.5mA.In case any measurement is out of the limits specified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.

ADJUSTMENT INSTRUCTION

1. Application RangeThis spec. sheet applies to PB12K Chassis applied PDP TVall 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 isolationtransformer will help protect test instrument.

(2) Adjustment must be done in the correct order. But it isflexible when its factory local problem occurs.

(3) The adjustment must be performed in the circumstance of25 cC ± 5 cC of temperature and 65 % ± 10 % of relativehumidity if there is no specific designation.

(4) The input voltage of the receiver must keep 100 V - 240 V,50 / 60 Hz.

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

(3) 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-AdjustMenu – 7. White Balance” there items “NONE, INNER,HDMI”. It is normally setting at inner basically. If you can’tadjust using inner pattern you can select HDMI item, andyou can adjust.

- In manual Adjust case, if you press ADJ button of serviceremocon, 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”.

O You must start “wb 00 00” and finish it “wb 00 ff”.O If it needs, then adjustment “Offset”.

(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 30minutes set let on Heat-run mode.

- Let CA-210 to zero calibration and must has gap more10cm from center of PDP module when adjustment.

- Press “ADJ” button of service remocon and select“7.White-Balance” in “Ez-Adjust” then press “G” buttonof navigation key. (When press “G” button then set willgo 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 thencontrol R, G gain adjustment High Light adjustment.

- If “Medium” and “Warm” mode Let R-Gain to 192 andR, G, B-Cut to 64 and then control G, B gainadjustment High Light adjustment.

- All of the three mode Let R-Gain to 192 and R, G, B-Cut to 64 and thencontrol 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 fromadjustment 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 Countryabout Rating and Time Zone.

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

(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 thefunction 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 100mASignal: 3KV/min at 100mA

(2) Test time: just 1 second.(3) Test point

- GND test: Test between Power cord GND and Signalcable metal GND.

- ESD test: Test between Power cord GND and Live andneutral.

(4) Leakage current: Set to 0.5mA(rms)

9. POWER PCB Ass’y VoltageAdjustment(Va/Vs Voltage Adjustment)

(1)Test equipment : D.M.M 1EA(2) Connection Diagram for Measuring : refer to fig.1
