Adjustment Instruction

1. Application

This document is applied to 20.1" LCD TV which is manufactured in Monitor Factory or is produced on the basis of this data.

2.Designation

2.1The adjustment is according to the order which is

designated and which must be followed, according to the plan which can be changed only on agreeing.

2.2.Power Adjustment : Free Voltage

2.3.Magnetic Field Condition: Nil.

2.4.Input signal Unit : Product Specification Standard

2.5.Reserve after operation : Above 30 Minutes

2.6.Adjustment equipments : Pattern Generator (MSPG-925L or Equivalent), DDC Adjustment Jig equipment, SVC remote controller

3.Adjustment

In order to enter to IIC_SW, press IN-START key by

using SVC remote controller and press VOL+ at 'ETC', after then, locate menu bar on 'IIC_SW' menu and change 0 or 1 by using VOL+ or VOL- Key.

-IIC_ SW "1" : Factory default (Shipping condition), DDC Communications(DDC2B)

-IIC_ SW "0": ADC calibration with auto adjustment

equipment.

*Menu(Local Key) + Menu(Remote controller: 6710T00022D) => Enter SVC Mode

3.1 Board Assembly line process

The machine can be adjusted by itself automatically but even for self -adjustment it needs someone to operate it.

3.1.1ISP Process ; UOC file (Main board check process)

At first, APC after manual inserting and inspection. And ISP needs to check main board Ass'y.

3.1.1.1Required Equipment

JIG for ISP or ( ISP JIG for SVC and LIPS )

PC that is installed with "WISP" program.

Control + Power LED PCB Ass'y

3.1.1.2 ISP Sequence

1)Connect main board with JIG for ISP

2)Execute "WISP" Program.

3)Compare UOC version with version of hex file.

4)Push "Brouse..." button and select hex file.

5)Push " Auto Execute" button.

6)Occur an Error, try again and again. 2)~5)

3.1.2ADC Process (Board Adjustment line process) 1) Auto Gain/Offset Adjustment

Convert to AV in Input-Mode

Signal equipment displays 0.7V, 16 Step Gray pattern. (Model:202, Pattern: 29 at MSPG925L)

-Output Voltage : 700 mVp-p

-Impress Resolution 576i and gray pattern that left & right is black and center is white signal which follows in the MSPG925L.

Adjust by commanding AUTO_COLOR_ADJUST (0xF1) 0x00 0x00 instruction.

2)Confirmation : Adjustment process

We confirm whether "0x01" address of EEPROM "0xA0" is "0xAA" or not.

If "0x01" address of EEPROM "0xA0" isn't "0xAA", we adjust once more in adjustment line by adjust method of 1).

We can confirm the ADC values from "0x0C~0x11" addresses in a page "0xA0"

3.1.3DCXO Adjustment

3.1.3.1DCXO Adjustment :

Convert to AV in Input-Mode

Signal equipment displays 0.7V, 8 Step color pattern. (Model:202, Pattern: 38 at MSPG925L)

-Output Voltage : 700 mVp-p

-Impress Resolution 576i and Color pattern which follows in the MSPG925L.

Adjust by commanding AUTO_DCXO (0xFC) 0x00 0x00 instruction.

* Caution*

If DDC CMD do n't work, please check below.

1.Enter SVC menu by SVC Remote controller

2.Enter "ETC" menu

Check please, IIC_SW is "0" or "1".

-IIC_SW "0" : ADC calibration with auto adjustment equipment..

-IIC_SW "1" : Factory default (Shipping condition), DDC Communications(DDC2B).

3.1.4 Function Check IIC_SW should set to "1"

Check DDC communications (DDC2B)

Check display and sound (cf. work instructions)

Check Input and Signal items.

1.TV

2.AV1 (SCART)

3.AV2 (CVBS/ S-Video)

4.Speaker & H/P Output

**After Fuction Check , IIC_SW should set to "0"
