1. Precautions and Safety Notices 1. Appropriate Operation (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) Turn off the product before cleaning. Use only a dry soft cloth when cleaning the LCD panel surface. Use a soft cloth soaked with mild detergent to clean the display housing. Use only high quality and safety approved AC/DC power adapter. Disconnect the power plug from AC outlet if the product is not used for a long period of time.
(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist nor bend the TFT Module even momentary. At designing the enclosure, it should be taken into consideration that no bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module may be damaged. (12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local ordinances or regulations for disposal.
5.2 Handling and Placing Methods Correct Methods: Incorrect Methods: Only touch the metal frame of the LCD panel or the front cover of the monitor. Do not touch the surface of the polarizer. Surface of the LCD panel is pressed by fingers and that may cause “Mura.” Take out the monitor with cushions Taking out the monitor by grasping the LCD panel. That may cause “Mura.
Placing the monitor on foreign objects. That could scratch the surface of the panel or cause “Mura.” Place the monitor on a clean and soft foam pad. The panel is placed facedown on the lap. That may cause “Mura.

3. Front Panel Function Control Description 1. Control Location Use the buttons on the front control panel to display and adjust the On View controls which display on the screen. Scrolls through menu options and adjusts the displayed control. Also a shortcut to display the Contrast/Brightness adjustment control screen. Displays the Main Menu or exits the control screen and saves adjustments Displays the control screen for the highlighted control.
Main Menu: Auto Image Adjust -- adjusts sizes and centers the screen image automatically. Contrast -- adjusts the difference between the image background (black level) and the foreground (white level). Brightness -- adjusts background black level of the screen image. Input Select -- toggles between inputs if you have more than one computer. Color Adjust -- provides several color adjustment modes: preset color temperatures and RGB, which allow you to adjust red (R), green (G), and blue (B) separately.
Setup Menu: Language -- allows you to choose the language used in the menus and control screens. Resolution Notice -- allows you to enable or disable the resolution notice. OSD Position -- allows you to move the on-screen display menus and control screens. OSD Timeout -- sets the length of time the on-screen display screen is displayed. For example, with a “30 second ” setting, if a control is not pushed within 30 seconds, the display screen disappears.
4. Circuit Description 1. Power supply (DC/DC Converter) The AP1501 is monolithic IC designed for M/B DC/DC converter, with the ability of driving a 3A load without any additional transistor component. The AP1501 operates at a switching frequency of 150 kHz and thus allows smaller-sized filter components than would be needed with lower frequency switch regulator. 2. Flash Memory The Pm39LV010R is a 1 Megabit, 3.3 Volt-only Flash Memory organized as 131,072 bytes of 8 bits each.
3. GM5120 The gm5110/20 is a graphic processing IC for Liquid Crystal Display (LCD) monitors at XGA/SXGA resolution. It provides all key IC functions required for the highest quality LCD monitors. On-chip functions include a high-speed triple-ADC and PLL, Ultra-Reliable DVI TM receiver, a high quality zoom and shrink scaling engine, an on-screen display (OSD) controller, digital color controls and an on-chip microcontroller (OCM).

Step 1. Let VG710 enter Burn In Mode. (Refer to Chapter III-3. Hot Keys for Function Controls). Step 2. Save these three files, and <710LG_V2_48.bin> in a hard disk (better in a root directory, e.g. C:\ or D:\ ). Step 3. Open file. Key in the path where you save the driver and firmware <710LG_V2_48.bin>.
Step 4. Execute Gprobe program. Step 5. Click Connection Setup icon. Select Protocol: DDC 2Bi3, Port: LPT1 (0x378), Speed: 70000.
Step 6. Before executing the firmware program, please test the connection between the monitor and fixtures. Key in “test” after “Gprobe,” and then press “Enter.” If the test result shows “passed,” it means the connection is well. If not (failed), it means the connection has problems. Then you need to check the setup procedure or reboot the PC, or simply use another PC to do the firmware upgrade.
Step 7. Key in “batch C:\VG710\bdisp.txt” after “Gprobe:”, and then press “Enter” key to begin programming automatically. Step 8.
Step 9. Unplug and replug power cord of VG710 and then enter “Burn In Mode” (Refer to Chapter III-3. Hot Keys for Function Controls). Check if the version of BIOS is correct. Step 10. At last, do “All Mode Reset.” Troubleshooting: 1. If the firmware upgrade fails at the last step, don’t unplug the power cord of the monitor. Just try the upgrade procedure again. (a) If there is error to execute the command at or before line10 in the “bdisp.

P3: to DVI-DVI Cable P2: to VGA Cable JP3 must be closed P1: to RS232 Cable JP1: to Power Adapter 3.
Step 1. Select and execute DDC Key In program. Step 2. Select “W/w - writing mode.
Step 3. Key in the serial number or use the barcode reader to scan the barcode of the monitor, and then press “Enter” key. Step 4. The successful picture is as follows. “The checksum values will appear after DDC is upgraded successfully in both VGA and DFP (DVI) modes.
Step 5. Let VG710 enter “Burn In Mode” (Refer to Chapter III-3. Hot Keys for Function Controls). Unplug and re-plug the power cord of the monitor. The corrective serial number will show on the screen. Step 6. Checking Method: - Execute the DDC Key In program and select “R/r - Reading mode” in Step 2. - Use barcode reader to scan the barcode of the monitor. If the DDC is correct, the “Send VGA” and “Send DFP” will show “Check Pass!” message.
