Important Safety Notice

Proper service and repair is important to the safe, reliable operation of all ASUS equipment. The service
procedures recommended by ASUS and described in this service manual are effective methods of performing
service operations. Some of these service operations require the use of tools specially designed for the purpose.
The special tools should be used when and as recommended.

It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully
read in order to minimize the risk of personal injury to service personnel. The possibility exists that improper service
methods may damage the equipment. It is also important to understand that these CAUTIONS and NOTICES ARE
NOT EXHAUSTIVE. ASUS could not possibly know, evaluate and advise the service trade of all conceivable ways
in which service might be done or of the possible hazardous consequences of each way. Consequently, ASUS has
not undertaken any such broad evaluation. Accordingly, who uses a service procedure or tool which is not
recommended by ASUS must first satisfy himself thoroughly that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.

FOR PRODUCTS CONTAINING LASER:
DANGER- Invisible laser radiation when open.

AVOID DIRECT EXPOSURE TO BEAM.
CAUTION- Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
CAUTION- The use of optical instruments with this product will increase eye hazard.

TO ENSURE THE CONTINUED RELIABILITY OF THIS PRODUCT, USE ONLY ORIGINAL MANUFACTURER'S
REPLACEMENT PARTS, WHICH ARE LISTED WITH THEIR PART
NUMBERS IN THE PARTS LIST SECTION OF THIS SERVICE MANUAL

Take care during handling the LCD module with backlight unit

- Must mount the module using mounting holes arranged in four corners.

- Do not press on the panel, edge of the frame strongly or electric shock as this will result in damage to the screen.

- Do not scratch or press on the panel with any sharp objects, such as pencil or pen as this may result in damage to
the panel.

- Protect the module from the ESD as it may damage the electronic circuit (C-MOS).

- Make certain that treatment body is grounded through wrist band.

- Do not leave the module in high temperature and in areas of high humidity for a long time.

- Avoid contact with water as it may as hort circuit within the module.

- If the surface of panel became dirty, please wipe it off with a soft material. (Cleaning with a dirty or rough cloth may
damage the panel.)

4 Block Diagram

4.1 Function block

PA246Q is a 24” WUXGA (1920x1200) resolution TFT LCD monitor. The monitor shall support VGA,

DVI, Displayport and HDMI with HDCP inputs. Moreover, PA246Q equips headphone out to enhance its

features and one USB upstream, two USB inputs and card reader. 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, and hotkey function is to offer users an

easy method to set some common functions by pressing several hotkeys which also include some auto

adjust functions.PA246Q also offer DDC/CI function to meet VESA standard.

A246Q consists of a head and a stand (base). The head consists of a LCD module with lamps, a

power board, a control board, a USB hub board and an interface BD.

A. Interface Board

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, and to provide DVI port equipped with HDCP key, for receiving

DVI signal to generate high quality image. In addition, it provides HDMI and Displayport input ports,

equipped with HDCP key, for receiving HDMI and Displayport signals to generate high quality image

and audio. The scaling IC has internal A/D converter, internal OSD and auto detect input timing

functions. A/D converter converts analog signal to digital data. OSD is offering adjustable functions to

end-user. Detect timing is for detect change mode. Scalar generates the pixel clock to the T-CON.

Finally output the digital RGB data, the Hsync, Vsync and pixel clock to LCD panel driver IC.MCU offers

H/W DDC2BI function & controls system processing. EEPROM is stored DDC data, OSD common data

and user mode data. A headphone audio circuit is also provided by interface board to add the

headphone output features.

(a) IC introduction

1. ST STDP8028 is an all-in-one LCD monitor controller supporting WUXGA, and integrates ST high

performance ADC, TMDS Rx with HDCP, scaling engine, OSD engine, LVDS Tx, and so on.

2. EEPROM: We use 24C32 to store all the adjustable data and user settings. The HDCP KEY is stored in

it.

3. Serial Flash: 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. SMSC USB2649 IC: The 2-port USB HUB is fully compliant with USB 2.0 specification and will attach to

an upstream port as a Full-/High- Speed HUB.

#2 Converter Circuit – L4978

The L4978 is a step down monolithic power switching regulator delivering 2A at a voltage between

3.3V and 50V (selected by a simple external divider). Realized in BCD mixed technology, the device

uses an internal power D-MOS transistor (with a typical R

of 0.25Ω) to obtain very high efficiency

DS(on)

and high switching speed.

A switching frequency up to 300 kHz is achievable (the maximum power dissipation of the

packages must be observed). A wide input voltage range between 8V to 55V and output voltages

regulated from 3.3V to 50V cover the majority of today’s applications.

Features of this new generation of DC/DC converter include pulse-by-pulse current limit, hiccup mode

for short circuit protection, voltage feed-forward regulation, soft-start, protection against feedback loop

disconnection, inhibit for zero current consumption and thermal shutdown.
