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 1MΩand 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.

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) The adjustment must be performed in the circumstance of
25 cC ± 5 cC of temperature and 65 % ± 10 % of relative
humidity 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.

V Adjustment Mapping information
OWhen Color temperature (White balance) Adjustment
(Automatically)
- Press “Power only key” of service remocon and
operate automatically adjustment.
- Set BaudRate to 115200.
OYou must start “wb 00 00” and finish it “wb 00 ff”.
OIf 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 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
* Attachment: White Balance adjustment coordination and color

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
