2. Introduction

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.

2.4. General Descriptions

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

Level 1: Cosmetic / Appearance / Alignment Service
Level 2: Circuit Board or Standard Parts Replacement
Level 3: Component Repair to Circuit Boards

3. Product Overview

3.1. Introduction

X193HQ is defined as our new 18.5W model in ACER X series which will be the ACER project in

Qisda. X193HQ is defined as 18.5”W LCD Monitor supports 1366(H) x 768(V) resolution with

DPMS (Display Power Management System) and ACER eColor function. There are triple input
types, D-sub, DVI. X193HQ adopts AUO panel M185XW01 V7. X193HQ has included 1W+1W
speaker. X193HQ also support ACM 8000000:1.(Theoretical value)

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.

frame) with Analog signals from Chroma video pattern generator.

2. Enter factory mode (press “e-Key” then press “power” button to turn on monitor).

3. Move black cursor into “BURN IN MODE” tag and select “ON” to enable burn-in mode, then
left OSD menu.

4. Change Color Temperature to User mode.

5. Press “ Left Key ” button to do white balance for auto color balance adjustment (will get
optimal gain / offset (clamp) values).

5.1.4 Color 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 “e-Key” then press “power” button to turn on monitor).

3. Confirm auto color balance adjustment had already been done.

4. Measure each color temperature (Cool&Warm) by Minolta CA-110 (or equivalent equipment).

5. Two methods can be used to adjust RED, GREEN, BLUE value of each color temperature,

Cool&Warm to meet following spec requirement, the 1st method is by using external PC and
IIC alignment protocol to do automatic adjustment, and the 2nd method is by manually and
must be in factory mode.

6. Turns off the monitor power.

6.2 Circuit Operation Theory

I. Introduction:

X193HQL is a 18.5 inch Wide and 24bits color TFT LCD monitor, which can

support the resolution up to 1366 x 768. It has VGA input and compliant with VESA
specification to offer a smart power management. The monitor has DDC/CI function to
make the monitor communicate with PC by Acer ADM DDC/CI software, and also it
has ACM function to let the monitor contrast ratio up to ?:1. It also offers OSD Menu
for users to control the adjustable items and get some information about this monitor.

II. Block diagram

X193HQL consists of a main body and a stand (base). The main body contains a AUO/

LGD/SEC TFT LCD module with LED Backlight, a power board (includes AC/DC、
DC/DC、 inverter and panel power source), a control board and an interface board.
The block diagram is shown as below.

III. Circuit operation theory:

A.) THE MAIN BODY:

A-1.) Interface board block diagram:

(a) Circuit operations:

The scaling IC has OSD and auto detecting input timing functions. OSD offers
adjustable functions to the end-users. Auto detecting timing function can detect change
modes. It outputs the digital R-G-B data, pixel clock and control signal to TCON of the LCD
module. A MCU, build in scaling IC (Realtek2525LH), is responsible for the system
processing. There are two external storing units, one is 24C16 to store the OSD function
data and user preset timings.

(b) IC introduction:

1.) Realtek2525LH SCALER IC:
Realtek2525LH series products are all-in-one LCD monitor controller with analog (RGB),
DVI and video inputs, supporting UXGA/ WXSGA+WXGA+/SXGA,and integrate Realtek
high performance ADC,scaling engine,LVDS Tx,and so on.Moreover,all products are pin

also includes an ITU656 video format input port with color space converter that makes it
an attractive solution for low cost MFM and TV applications. The output section contains
a 24-bit TTL output interface and a channel LVDS transmitter for direct interfacing of
commercially available LVDS LCD panel modules. In addition, RTD2525LH embedded

16.5KSRAM dynamically stores OSD command and fonts, compatible advanced color
control features.

2.) EEPROM:
We use 24C16 EEPROM to store monitor user data and user preset timings. There are
16 user timing modes are automatically saved in it. Each timing mode is allocated with

22 bytes of memory space for information such as Sync frequencies, polarities… etc.

PC can access the EEPROM data indirectly through the SDA and SCL channels of DVI
and D-sub (IIC communication). The digital and analog DDC data are stored in two
24C02s EEPROM.
