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.
2.3 .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:
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
V193W is defined as our new 19”W model in ACER V series which will be the ACER project in Qisda. V193W is
defined as 19”W LCD Monitor supports 1440(H) x 900(V) resolution with DPMS (Display Power Management
System) and ACER eColor function. There are triple input types, D-sub, DVI. V193W adopts AUO panel
M190PW01 V5, LGD panel LM190WX1-TLP1, SEC panel LTM190BT03. V193W has included 1W+1W speaker.
V193W 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.

When Vertical Frequency is over 76Hz or under 56Hz, the display is Black and showing “Input Not
Supported” warning message. (Some video timings are except for PAL, 50Hz signals.)
2. If Hf /Vf is set in the range of 31KHz~83KHz and 56Hz ~76Hz (not including some video timing), and Pixel
Clock is set in the range of 25.175MHz~173MHz(DVI and HDMI input port 165MHz for Single-Link), but is
not the above Resolution, then it will display the nearest mode.

5.1.1 Preparation:
1.) Setup input timing to any preset modes or patterns.
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.) Power off the monitor, remove the input source and then power on again.
5.) Setup unit and keep it warm up for at least 30 minutes.
6.) Setup input timing ICL-605( 1280x1024@75Hz ), 32-Grays pattern.
7.) Setup unit and keep it warm up at least 30 minutes.
5.1.2 Timing adjustment: (Analog only, it is not required for DVI-D input source)
1.) Enter factory setting area (press “Empowering” and then press “SOFTPOWER”).
2.) Check the settings to following values:
Contrast = 50
Brightness = 85
Color = Warm
Language = English
Then, turn off the monitor power.
3.) Turn on power enter user area.

Note:
1. Show “Input Not Supported” warning message.
When Vertical Frequency is over 76Hz or under 56Hz, the display is Black and showing “Input Not
Supported” warning message. (Some video timings are except for PAL, 50Hz signals.)
2. If Hf /Vf is set in the range of 31KHz~83KHz and 56Hz ~76Hz (not including some video timing), and
Pixel Clock is set in the range of 25.175MHz~173MHz(DVI and HDMI input port 165MHz for SingleLink), but is not the above Resolution, then it will display the nearest mode.
5.1.3 ADC calibration (Auto color balance adjustment)
~~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.

5.1.5. 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).
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 C212 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:
V193W is a 19 inch and 24bits color TFT LCD monitor, which can support the resolution up to 1280 x 1024. 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 10000:1. It also offers OSD Menu for users to control the
adjustable items and get some information about this monitor.
II. Block diagram
V193W consists of a main body and a stand (base). The main body contains a AUO/ LGD TFT LCD
module with 2 CCFL lamps, 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 Implementations:
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 compatible in QFN 48-pin package to save cost and
make the design easier. The RTD 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,

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.
