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
damage d by accidental sho rt s of the circui tr y 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 M
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.
Ω and 5.2 MΩ.
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 vol ta ge
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.
-> PU21A/PB21A : USE INTERNAL ADC(LM1) : using internal
pattern.
5.1. Auto Adjust Component 480i/1080p RGB

■ Summary : Adjustment component 480i/1080i and RGB
1080p is Gain and Black level setting at Analog
to Digital converter, and compensate the RGB
deviation
■ Using instrument
● Adjustment remocon, 801GF(802B, 802F, 802R) or
MSPG925FA pattern generator
( It can output 480i/1080i hor izontal 100% color bar
pa tter n sig nal , and i ts ou tput leve l mus t set tin g
● Set Component 480i mode and 100% Horizontal Color
Bar Pattern( H o z T V 3 1 B a r ) , t h e n s e t T V s e t t o
Component1 mode and its screen to “NORMAL”
● ADC 1080p Component1 / RGB adjustment
- Check connection both of Component1 and RGB
- MSPG-925FA -> Model: 225, Pattern 65
● Set Component 1080p mode and 100% Horizontal Color
Bar Pattern( H o z T V 3 1 B a r ) , t h e n s e t T V s e t t o
Component1 mode and its screen to “NORMAL”
● After get each the signal, wait more a second and enter
the “IN-START” with press IN-START key of Service
remoco n. After then select “7. External ADC” wit h
navigator button and press “Enter”.
● After Then Press key of Service remocon “Right Arrow
(VOL+)”
● You can see “ADC Component1 Success”
● Component1 1080p, RGB 1080p Adjust is same method.
● Component 1080p Adjustment in Component1 input
mode
● RGB 1080p adjustment in RGB input mode
● If you success RGB 1080p Adjust. You can see “ADC
RGB-DTV Success”
* caution : Set Volume 0 after adjustment
5.2. Use Internal ADC(S7R)
- A D J ( EZ ADJ U S T ) -> 6. A D C C a l i bration -> ADC
Calibration(START)
* EDI D (The Extended Display Identification Data)/DDC
(Display Data Channel) Download.
■ Summary
● It is established in VESA, for communication between
PC and Monitor without order from user for building
user condition. It helps to make easily use realize
“Plug and Play” function.
● For EDID data write, we use DDC2B protocol.
- Auto Download
■ After enter Service Mode by pushing “ADJ” key,
■ Enter EDID D/L mode.
■ Enter “START” by pushing “OK” key.
* Caution:
- Never connect HDMI & D-sub Cable when the user
downloading .
- Using LCD 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.
● Auto-adjustment Equipment (It needs when Auto-adjustment – It is availed communicate with RS-232C : Baud
rate: 115200)
● Video Signal Generator MSPG-925F 720p, 216Gray

■ 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
