This section contains general service information, please read through carefully. It should be

stored for easy access place for quick reference.

2.1 RoHS (2002/95/EC) Requirements

– Applied to all countries require RoHS.

The RoHS (Restriction of Hazardous Substance in Electrical and Electronic Equipment Directive)

is a legal requirement by EU (European Union) for the global electronics industry which sold in EU

and some counties also require this requirement. Any electrical and electronics products

launched in the market after June 2006 should meet this RoHS requirements. Products launched

in the market before June 2006 are not required to compliant with RoHS parts. If the original

parts are not RoHS complaints, the replacement parts can be non ROHS complaints, but if the

original parts are RoHS compliant, the replacement parts MUST be RoHS complaints.

If the product service or maintenance require replacing any parts, please confirming the RoHS

requirement before replace them.

2.2 Safety Notice

1. Make sure your working environment is dry and clean, and meets all government safety

requirements.

2. Ensure that other persons are safe while you are servicing the product.

DO NOT perform any action that may cause a hazard to the customer or make the product

unsafe.

3. Use proper safety devices to ensure your personal safety.

4. Always use approved tools and test equipment for servicing.

5. Never assume the product’s power is disconnected from the mains power supply. Check that

it is disconnected before opening the product’s cabinet.

6. Modules containing electrical components are sensitive to electrostatic discharge (ESD).

Follow ESD safety procedures while handling these parts.

7. Some products contain more than one battery. Do not disassemble any battery, or expose it to

high temperatures such as throwing into fire, or it may explode.

8. Refer to government requirements for battery recycling or disposal.

2.3 Compliance Statement

Caution: This Optical Storage Product contains a Laser device. Refer to the product specifications

and your local Laser Safety Compliance Requirements.

2.4 General Descriptions

This Service Manual contains general information. There are 3 levels of service:

3. Product Overview

3.1 Introduction

X203H is defined as our new 20’W model in ACER V series which will be the ACER project in

Qisda. X203H is defined as 20’W LCD Monitor supports 1600(H) x 900(V) resolution with DPMS

(Display Power Management System) and ACER eColor function. There are double input types,

D-sub, and DVI. X203H adopts SEC LTM200KT03 and LGD LM200WD1-TLC1. V203H has

included 1W+1W speaker.X203H also support ACM 10000:1.

The features summary is shown as below,

*All panel spec. in Q201 definition depends on the variance of panel source.

*All spec. of monitor need to warm up at least 1hr.

* To test the “Contrast Ratio” and “Luminance” functions, the color status must be “User preset”

mode.

* 1. “Contrast Ratio”: Set “brightness” at 100, and “contrast” at 50.

* 2. “Luminance”: Set “brightness” at 100, and “contrast” at 100.

~~Analog only, it is not required for DVI-D input source

1. Setup input timing ICL-605( 1280x1024@75Hz ), pattern 42(5-Mosaic pattern with white

color block) with Analog signals from Chroma video pattern generator. (it depends on Scaler

IC supplier’s recommendation)

2. Enter factory mode (press “Empowering” & “Power” buttons at the same time to turn on

monitor).

3. Move cursor into “Burn-in Mode” tag and select “On” to enable burn-in mode.

4. Close OSD menu then press “Auto” button for auto color adjustment. (This procedure will get

optimal gain/offset(clamp) values)

5. Checking if the picture is ok, or reject this monitor and check its circuit board or wire/cable

connection.

5.1.4 Color temperature adjustment

1. Setup input timing to any preset modes, pattern 41(full white color pattern) with Analog

signals from Chroma video pattern generator.

2. Enter factory mode (press “Empowering” & “Power” buttons at the same time to turn on

monitor).

3. Move cursor into “Burn-in Mode” tag and select “On” to enable burn-in mode.

4. Make sure ADC calibration (auto color balance adjustment) had already been done.

5. Measure color temperature by Minolta CA-110 (or equivalent equipment).

6. Adjust the color temperature ~~ Two methods can be used to adjust RED, GREEN, BLUE

value of each color temperature, C0/Cool, C1/User & C2/Warm to meet following spec

requirement, the 1^stmethod is by using external PC and IIC alignment protocol to do

automatic adjustment, and the 2^ndmethod is by manually and must be in factory mode.

5.1.5. Writing EDID data into monitor

1. Setup a PC with DDC card.

2. Connect PC to monitor with a D-sub signal cable.

3. Please refer to the Q212 for the correct EDID file.

4. Runs the writing program to write the analog EDID data into EEPROM for analog input(ie.

15-pin D-sub).

- 36 -

5. Repeat step 4 and write the digital EDID data into EEPROM for DVI-D input(ie. 24-pin DVI-

D).

6. Read both EEPROM data and confirm it to match with the Q212 definition.

(Note : The DVI-D input may not operation correctly if the digital EDID data do not exist.)

6.2 Circuit Operation Theory

I. Introduction

The X203H is a 20” W (1600x900), LCD type is TN+Film and Normally White, 16.7M colors(R, G, B 6-

bit data + Hi-FRC data) TFT LCD with HDCP support monitor. It’s have dual (D-SUB and DVI)

interface LCD monitor with a 15 pins D-sub signal cable and 24 pin DVI signal cable which support

HDCP function. It’s compliant with VESA specification to offer a smart power management and power

saving function. It also offers OSD menu for users to control the adjustable items and get some

information about this monitor. The best function is to offer users an easy method to change input

source, DDC/CI Enable and Auto Adjustment items well done just by pressing hot key, we called it

“Input Select”, “DDC/CI” and “Auto” which can manual controlled items.

X203H also offer DDC/CI function to meet VESA standard.

II. Block diagram

The X203H consists of a LCD module with 2 lamps, a power board, a control board, and an

interface board. The block diagram is shown as below.

(a) Circuit operations:

A basic operation theory for this interface board is to convert analog signals of Red, Green

and Blue to digital signals of Red, Green and Blue. The scaling IC has internal A/D converter,

internal OSD, built in LVDS transmitter and auto-detect input timing functions. A/D converter

is convert analog signal to digital data. OSD is offering adjustable functions to end-user.

Detect timing is for detect change mode. LVDS transmitter is used to compress the digital

RGB data, the Hsync, Vsync and pixel clock generated by Scaling then output to LCD

module. MCU stores source code and offers H/W DDC2Bi function & controls system

processing. EEPROM is stored DDC and HDCP data, OSD common data and user mode

data.

(b) IC introduction:

1.) DDC (Display Data Channel) function: We use DDC IC to support DDC2Bi function. DDC

data is store in 24C02 (EEPROM). Those data related to LCD monitor specification. PC

can read them by “SDA” and “SCL” serial communication for I²C communication for

DDC2Bi.

2.) Scalar IC: There are A/D, TMDS receiver, HDCP, Scaling, OSD and LVDS transmitter

functions built-in the RTD2545LH IC. Scaling IC is revolutionary scaling and color engine,

- 58 -

capable of expanding any source resolution to a highly uniform and sharp image or down

scaling from 1980x1020, combined with the critically proven integrated 8 bit triple-ADC

and patented Rapid-lock digital clock recovery system. It also support detect mode and

DPMS control.

3.) RTD2120L: Control unit, it controls all the functions of this interface board, just like the

OSD display setting, the adjustable items, adjusted data storage, the external IIC

communication, support DDC2Bi. .

4.) EEPROM: We use 24C016 to store all the adjustable data, user settings and HDCP Key

and use 2 of 24C02 to store DVI and D-SUB EDID data.
