Preface

Before using this information and the produc t it suppor ts, please read the following gener al information.

1. this Service Guide provides you with all technical information rela ting to the BASICCONFIGURATION
decided for Acer’s “global” pro duct offering. To better fit local market requireme nts and enhance product
competitiveness, your regional office MAY have decided to extend the functionality of a machine (e.g.
add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered
in this generic service guide. In such cases, please contact your regional offices or the responsible
personnel/channel to provide you with further technical details.

2. please not WHEN ORDERING FRU PARTS, that you should check the most up-to-date information
available on your regional web or channel. If, for whatever reason, a part number change is made, it will
not be noted in the printed Service Guide, for ACER-AUTHORIZED SERVICE PROVIDERS, your Acer
office may have a DIFFERENT part number code to those given in the FRU list of this printed Service
Guide. You MUST use the list provided by your regional Acer office to order FRU parts for repair and
Service of customer machines.

interference by one or more of the following measures:

1. Reorient or relocate the receiving an tenna.

2. Increase the separation betwee n the equipment and receiver.

3. Connect the equipment into an outlet on a circuit differe nt from that to which the receiver is
connected.

4. Consult the dealer or an experienced radio/TV technician for help.

NOTICE:

1. The changes or modifications not expressly approved by the party responsib le f or compliance could
void

the user’s authority to operate the equipment.

WARNING:

T o prevent fire or chock hazard, do not expose the monitor to r ain or moisture. Dangerously high voltages

are present inside the monitor. Do not open the cabinet. Refer servicing to qualified personnel only.

PRECAUTIONS

z Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub,

Swimming pool or in a wet basement.

z Do not place the monitor on an unstable trolley, stand, or table. If the monitor falls, it can injure a

person and cause serious damage to the appliance. Use only a trolley or stand recommended by the
manufacture or sold with the monitor. If you mount the monitor on a wall or shelf, use a mounting
kit approved by the manufacture and follow the kit instructions.

z Slots and openings in the back and bottom of the cabinet area provided for ventilation. To ensure

reliable operation of the monitor and to protect it from ov erheating, be sure these openings are not
blocked or covered. Do not place the monitor on a bed, sofa, rug or similar surface. Do not place the
monitor near or over a radiator or heat register. Do not place the monitor in a bookcase or cabinet
unles s proper ventila tion is provided.

z The monitor should be oper ated only from the type of power source indicated o n the label. If you are

not sure of the type of power supplied to your home, consult your dealer or local power company.

z The monitor is equipped with a three-pronged grounde d plug, a plug with a third (grounding) pin.

This plug will fit only into a grounded power outlet as a safety feature. If your outlet does not
accommodate the three-wire plug, have an electrician install the correct outlet, or use an adapter to
ground the appliance safely. Do not defeat the safety purpose of the grounded plug.

z Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will

protect the monitor from damage due to power surges.

z Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
z Never push any object into the slot o n the monitor cabinet. It could shor t circuit parts causing a fire

or electric shock. Never spill liquids on the monitor.

z Do not attempt to service the monitor yourself; opening or removing covers can expose you to

dangerous voltages and other hazards. Please refer all se rvicing to qualified service personnel.

z To ensure satisfactory operation, use the monitor only with UL listed computers which have

appropriate configured receptacles marked between 100-240V AC, Min. 3.5A.

z The wall socket shall b e installed nea r the equipment and shall be easily accessible.
z For use only with the attached power adapter (output 12V DC) which have UL,CSA listed license

SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem.

NOTES

z Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power

Switch and then turn it on again to make sure the flicker disappears.

z You may find slightly uneven brightness in the screen depending on the desktop pattern you use.
z The LCD screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less

such as a missing pixel or a pixel lit all of the time.

z Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switchin g

the imag e, wh en t he s ame ima ge is d isp la y ed fo r ho ur s. I n th is c as e, th e s cre e n is re co v er e d slo wly
by changing the image or turning off the P ower Switch for hours.

HOW TO OPTIMIZE THE DOS-MODE

Plug and play

Plug & play DDC2B feature

This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC ST ANDARD. It allows
the monitor to inform the host system of its identity and, depending on the level of DDC used,
communicate additional information about its display capabilities. The communication channel is defined
in two levels, DDC2B.
The DDC2B is a bi-directional data channel based on the I
information over the DDC2B chan nel.

C protocol. The host can request EDID

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNA L.
IN ORDER FOR THIS MONITOR TO OPERATE PROPERLY, THERE MUST BE A VIDEO INPUT
SIGNAL.

This monitor meets the Green monitor standards as set by the Video Elec tronics Standards
Association(VESA) and/or the United States Environmental Protection Agency (EPA) and The Swedish
Confederation Employees (NUTEK). This feature is designed to conserve electrical energy by reducing
power consumption when there is no video-input signal pre sent. When there is no video input signal th is
monitor, following a time-out period, will automatically switch to an OFF mode. This reduces the monitor’ s
internal power supply consumption. After the video input signal is restored, full power is re stored and the
display is automatically redrawn. The appearanc e is similar to a “Screen Saver” feature except the display
is completely o ff. The display is re stored by pressing a key on the keyboard, or clicking the mouse.

USING THE RIGHT POWER CORD

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and
is UL listed and CSA labeled. The voltage rating for the power cord shall be 125 volt AC.
Supplied with units intended for connection to power outlet of personal computer : Please use a cord set
consisting of a minimum No. 18 AWG, type SJT or SVT three conductors flexible cord. One end terminates
with a grounding type attachment plug, rated 10A, 250V,CEE-22 male configuration. The other end
terminates with a molded-on type connector body, rated 10A, 250V, having standard CEE-22 female
configuration.
Please note that power supply card needs to use VDE 0602, 0625, 0821 approval power cord in European
counties.

Machine assembly

This chapter contains step-by-step procedures on how to assemble the monitor for
maintenance and trouble shooting
NOTE: 1. The screws for the different components vary in size. During the disassembly process, group

the screws with the corresponding to avo id mismatch when putting back the components.

2. Note: The monitor surface is susceptible to scratching! Therefore, lay the monitor on a soft
surface when mounting or removing the base.

3. Wear gloves.
