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. Specification
Introduction
GL2055/GL2055A/GL2055M is defined as an 20” WXGA++ 16:9 wide entry level LCD monitor.
The monitor supports maximum resolution up to 1600x900. The monitor shall support the VGA
and DVI (optional) with HDCP input.
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 80.
* 2. “Luminance”: Set “brightness” at 100, and “contrast” at 100.
