Only for training and service purposes
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 the 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 exposed metallic part. 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 100% 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
(Especially sharp distinction 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
■ RS-232C Command (Commonly apply)
● “wb 00 00”: Start Auto-adjustment of white balance.
● “wb 00 10”: Start Gain Adjustment (Inner pattern)
● “jb 00 c0” :
● …
● “wb 00 1f”: End of Adjustment
* If it needs, offset adjustment (wb 00 20-start, wb 00 2f-
end)
● “wb 00 ff”: End of white balance adjustment (inner pattern
disappear)
■ Adjustment Mapping information
● When Color temperature (White balance) Adjustment
(Automatically)
- 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
* Attachment: White Balance adjustment coordination and
