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 Replacement Parts List.
It is essential that these special safety parts should be replaced ith the same components as recommended in this manual to
prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design ithout permission of manufacturer.
General Guidance
An lsolation Transformer should always be used during
the servicing of a receiver hose chassis is not isolated from
the AC po er line. Use a transformer of adequate po er rating
as this protects the technician from accidents resulting in
personal injury from electrical shocks.
It ill also protect the receiver and it's components from being
damaged by accidental shorts of the circuitary that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blo n, replace
it ith the same specified type.
When replacing a high attage resistor (Oxide Metal Film
Resistor, over 1W), keep the resistor 10mm a ay from PCB.
Keep ires a ay from high voltage or high temperature parts.
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source,
connect an electrical jumper across the t o AC plug prongs.
Place the AC s itch in the on positioin, 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 bet een 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 belo Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check
Connect 1.5K/10 att resistor in parallel ith a 0.15uF capacitor
bet een a kno n good earth ground (Water Pipe, Conduit, etc.)
and the exposed metallic parts.
Measure the AC voltage across the resistor using AC
voltmeter ith 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC
voltage measurements for each esposed metallic part. Any
voltage measured must not exceed 0.75 volt RMS hich is
corresponds to 0.5mA.
In case any measurement is out of the limits sepcified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.

ADJUSTMENT INSTRUCTIONS
8. Adjustment of White Balance
8-1. The Purpose and Principal of Color
Temperature Adjustment
(1) Purpose: to reduce the difference in color temperature
among modules
(2) Principal: A module is in full dynamic range when RGB
Gain on OSD is 192. To adjust the white balance without
causing full dynamic range and full data, fix one of RGB
Gains at 192 and control the other two by reducing them
from 192.
8-2. Required Equipment
(1) Color Analyzer : CA-100+(CH 10), CA-100(CH 10) or CA-
210(CH 10)
=> To adjust color temperature of Plasma, CS-1000 is the
Color Analyzer and should be set to use CH 10 in which
white, red, green, and blue color are corrected. Conduct
the adjustment according to the coordinates for White
Balance adjustment in the table below.
In the case of using color-corrected CA-100, CA-100+,
and CA-210 (using CH10) to adjust Plasma, there are
differences for CS-1000 in the result due to the
characteristics of a module or filter. The target values of
the color coordinates in the table below are given to
prevent it.
(2) Automatic adjustor (with automatic adjustment necessity
and the RS-232C communication being possible)
8-3. Connection Diagram of Equipment
for Measuring (Automatic Adjustment)
Use the internal pattern to adjust White Balance. The pattern
is automatically given when the automatic adjustment device
is connected or when a user presses ADJ on the remote
controller to start Ez Adjust and then selects 6.White-Balance.
[Requirements for Automatic Adjustment
(1) The illuminance of surroundings
10 lux or less; preventing light in surroundings as much as
possible
(2) The location of the Probe
1) For PDP: place the color analyzer (CA-100, CA-100+,
and CA-210) close to the surface of a module and start
the adjustment.
2) For LCD: place the color analyzer (CA-210) close to the
surface of a module within 10 cm and keep the probe of
the color analyzer at 80°to 100°angle from the surface
of a module.
(3) Aging time
1) Once Aging is started, keep the power on without power
supply interruption for at least 15 minutes for heat run.
2) For PDP, use the internal pattern to adjust White
Pattern.
3) For LCD, use NO SIGNAL or Full White Pattern to
ensure the backlight is turned on.
8-4. Adjustment of White Balance
(Automatic Adjustment)
(1) Turn on the POWER ON(Â) of the remote controller to set
the adjustment and then start the automatic adjustment or
set the Baud Rate to 115200.Â) of the remote controller to
(2) Start the adjustment from “wb 00 00”and complete it at
“wb 00 ff”. (Adjust the offset if necessary)
wb 00 00 the automatic adjustment of White Balance is
started.

ADJUSTMENT INSTRUCTIONS
[RS-232C Command (Automatic Adjustment)
[42PC5D-UC] & [50PC5D-UC]
[WARNING] RGB-Cut fixed value
If the model has a fixed value, the equivalent value
must be applied.
Fix one of three Gains (R Gain, G Gain, and B Gain)
at 192 and control the other two by reducing values
from 192.
8-5. Adjustment of White Balance
(Manual Adjustment)
Required Equipment: CA-100 (CH 10), CA-100+ (CH 10), CA-
210 (CH-10)
--> To adjust color temperature of Plasma, CS-1000 is the
Color Analyzer and should be set to use CH 10 in which
white, red, green, and blue color are corrected. Conduct
the adjustment according to the coordinates for White
Balance adjustment in the table below.
(1) Enter ‘Ez - Adjust’by pressing ADJ KEY on the Service
Remote Control.
(2) Select "9. TEST PATTERN" using CH +/- Key and HEAT
RUN at least 30 minutes by pressing the ENTER Key.
(3) Zero Calibrate of the Color Analyzer, then attach sensor to
PDP module surface when you adjust.
(4) Select ‘6. White-Balance’of ‘Ez - Adjust’by pressing the
ADJ KEY on the Service R/C. Then enter adjustment mode
by pressing the Right KEY (
G ) .
(The internal pattern of full white appears by pressing
G )
(5) The adjustment is conducted in three levels of color
temperature; COOL, MEDIUM, and WARM.
[WARNING] RGB-Cut fixed value
If the model has a fixed value, the equivalent
value must be applied.
[Color temperature: Cool, Medium, Warm
(1) When R Gain is fixed at 192,
Control G Gain and B Gain by reducing them from 192.
(2) When B Gain is fixed at 192,
Control R Gain and G Gain by reducing them from 192.
(3) When G Gain is fixed to 192,
Control R Gain and B Gain by reducing them from 192.
Fix one of three Gains (R Gain, G Gain, and B Gain) at 192
and control the other two by reducing values from 192 to
prevent it from increasing.
(When RGB Gains are all 192, the module is in full dynamic
range.)
