ADJUSTMENT INSTRUCTION
1. Application Range
This spec. sheet applies to PU21A 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 100-240
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.
3. Adjustment items

5.1. Auto Adjust Component 480i/1080p RGB
1080p
■ 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 horizontal 100% color bar
pattern signal, and its output level must setting
0.7V±0.1V p-p correctly)
● You must make it sure its resolution and pattern cause
every instrument can have different setting
● Adjustment method 480i Comp1, Adjust 1080p Comp1/
RGB (Factory adjustment)
● ADC 480i Component1 adjustment
- Check connection of Component1
- MSPG-925FA -> Model: 209, Pattern 65
● Set Component 480i mode and 100% Horizontal Color
Bar Pattern(HozTV31Bar), then set TV set to
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

communication.
- Adjustment Color Temperature(White balance)
■ Using Instruments
● Color Analyzer: CA-210 (CH 10)
- 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-adjust-
ment – It is availed communicate with RS-232C : Baud
rate: 115200)
● Video Signal Generator MSPG-925F 720p, 216Gray
(Model: 217, Pattern 78)
■ Connection Diagram (Auto Adjustment)
● Using Inner Pattern
● Using HDMI input
■ 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
