This spec. sheet applies to PU11L Chassis applied PDP TV
all models manufactured in TV factory.

(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) 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

After Receive 100% Full white pattern (06CH) then
process Heat-run 

(or “8. Test pattern” condition of Ez-Adjust status)

V

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. 

(1) Adjust 480i Comp1 
(2) Adjust 1080p Comp1/RGB 

- If it is necessary, it can adjustment at Manufacture Line
- You can see set adjustment status at “9. ADJUST

CHECK” of the “In-start menu” 

(1) EDID (The Extended Display Identification Data )
(2) Color Temperature (White Balance) Adjustment
(3) Make sure RS-232C control
(4) Selection Factory output option

- Adjust 3 items at 3-1 PCB assembly adjustments

PU11A / PB11A : USE INTERNAL ADC(S7R) : using internal

pattern.

(1) Summary : Adjustment component 480i/1080i and RGB

1080p is Gain and Black level setting at Analog
to Digital converter, and compensate the RGB
deviation

(2) Using instrument 

1) 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 
0.7 V ± 0.1 V p-p correctly)

* You must make it sure its resolution and pattern cause every

instrument can have different setting

2) Adjustment method 480i Comp1, Adjust 1080p

Comp1/RGB (Factory adjustment)

O 

ADC 480i Component1 adjustment -

- Check connection of Component1 
- MSPG-925FA Ë Model: 209, Pattern 65

O

Set Component 480i mode and 100% Horizontal
Color Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to “NORMAL” 

O

- MSPG-925FA Ë Model: 225, Pattern 65

O

Set Component 1080p mode and 100% Horizontal
Color Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to “NORMAL” 

O

After get each the signal, wait more a second and
enter the “IN-START” with press IN-START key of

(1) Summary

1) 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. 

2) For EDID data write, we use DDC2B protocol.

(1) After enter Service Mode by pushing “ADJ” key,
(2) Enter EDID D/L mode.
(3) Enter “START” by pushing “OK” key. 

Caution 
- Never connect HDMI & D-sub Cable when the user

downloading .

- Use the proper cables below for EDID Writing.

(1) Write HDMI EDID data

1) Using instruments

- Jig. (PC Serial to D-Sub connection) for PC, DDC

adjustment.

- S/W for DDC recording (EDID data write and read)
- D-sub jack
- Additional HDMI cable connection Jig.

2) Preparing and setting.

- Set instruments and Jig. Like pic.5), then turn on PC

and Jig. 

- Operate DDC write S/W (EDID write & read)
- It will operate in the DOS mode.
