1. Precautions and Safety Notices 1.1 Safety Precautions This monitor is manufactured and tested on a ground principle that a user’s safety comes first. However, improper use or installation may cause damage to the monitor as well as the user. Carefully go over the following WARNINGS before installing and keep this guide handy. WARNINGS ．This monitor should be operated only at the correct power sources indicated on the label on the rear end of the monitor.
1.4 Handing and Placing Methods (Take VX2265wm for example) Correct 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. Take out the monitor Place the monitor on a clean and soft foam pad. Incorrect Methods: Surface of the LCD panel is pressed by fingers and that may cause “Mura.” Taking out the monitor by grasping the LCD panel. That may cause “Mura.” Placing the monitor on foreign objects.
Place the monitor on the lap, the panel surface must The panel is placed facedown on the lap. That may be upwards. cause “Mura.

3. Front Panel Function Control Description Use the buttons on the front control panel to display and adjust the OSD controls which display on the screen. The OSD controls are explained at the top of the next page and are defined in “Main Menu Controls”.
Do the following to adjust the display setting: 1. To display the Main Menu, press button [1]. NOTE: All OSD menus and adjustment screens disappear automatically after about 15 seconds. This is adjustable through the OSD timeout setting in the setup menu. 2. To select a control to adjust, press ▲ or ▼ to scroll up or down in the Main Menu. 3. After the desired control is selected, press button [2]. A control screen like the one shown below appears.
Main Menu Controls Adjust the menu items shown below by using the up ▲ and down ▼ buttons. Control Explanation Auto Image Adjust automatically sizes, centers, and fine tunes the video signal to eliminate waviness and distortion. Press the [2] button to obtain a sharper image. NOTE: Auto Image Adjust works with most common video cards. If this function does not work on your LCD display, then lower the video refresh rate to 60 Hz and set the resolution to its pre-set value.
Information displays the timing mode (video signal input) coming from the graphics card in the computer, the LCD model number, the serial number, and the ViewSonic® website URL. See your graphics card’s user guide for instructions on changing the resolution and refresh rate (vertical frequency). NOTE: VESA 1920 x 1080 @ 60Hz (recommended) means that the resolution is 1920 x 1080 and the refresh rate is 60 Hertz. Manual Image Adjust displays the Manual Image Adjust menu. H./V.
Language Select allows the user to choose the language used in the menus and control screens. Resolution Notice advises the optimal resolution to use. OSD Position allows the user to move the OSD menus and control screens. OSD Timeout sets the length of time the OSD screen is displayed. For example, with a “15 second” setting, if a control is not pushed within 15 seconds, the display screen disappears. OSD Background allows the user to turn the OSD background On or Off.
4. Circuit Description 4.1 Main Board NT68667UFG/C（U401） The NT68167 is a highly integrated flat panel display controller that interfaces analog, digital, and video inputs. It combines a triple ADC, a high quality zoom and shrink engine, a multi-color on screen display (OSD) controller and many other functions in a single chip. It provides the user with a simple, flexible and cost-effective solution for various flat panel display products.
Pin Assignment 14
AP1117D33L (U701) and AP1117E18LA (U704): DC power convert, convert to 3.3V and 1.8V AP1117 is a low dropout positive adjustable or fixed-mode regulator with 1A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply. AP1117 is also well suited for other applications such as VGA cards. AP1117 is guaranteed to have lower than 1.
4.2 Power Board IC901 LD7576 The LD7576X series bring high performance, combines with highly integrated functions, protections and EMI-improve solution. It’s an ideal solution for those cost-sensitive system, reducing component count and overall system cost. The LD7576X series features near-lossless high voltage startup circuit, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation.
Block Diagram Pin Name Function This pin is to program the frequency of the low frequency timer. By connecting a capacitor to 1 CT ground to set the OLP delay time. And this pin can be used for latch mode protection. By pulling this pin lower than 0.8 V, the controller will be entered latch mode until the AC power-on recycling. Voltage feedback pin (same as the COMP pin in UC384X), By connecting a photo-coupler to 2 COMP close the control loop and achieve the regulation.
IC801 TA9687GN TA 9687 is a high performance, cost-effective CCFL (Cold Cathode Fluorescent Lamp) controller designed for driving large-size Liquid Crystal Display (LCD) applications requiring 2 to 6 CCFLs. The controller converts unregulated DC voltages into a nearly sinusoidal lamp voltage and current waveforms. The TA 9687 supports full-bridge power conversion topologies while maintaining high-efficiency operation.
Pin Description Pin No.
5. Adjustment Procedure Setting the Timing Mode Setting the timing mode is important for maximizing the quality of the screen image and minimizing eye strain. The timing mode consists of the resolution (example 1920 x 1080) and refresh rate (or vertical frequency; example 60 Hz). After setting the timing mode, use the OSD (On-screen Display) controls to adjust the screen image. For the best picture quality set your LCD display timing mode to: VESA 1920 x 1080 @ 60Hz. To set the Timing Mode: 1.
Gain adjustment: Move cursor to “Factory” and press “2” key. Move cursor to “ Auto Level” and press “2” key to adjust Gain and Offset automatically; (notice：this monitor do auto level must in T144(1280X1024@60Hz) P48(32 Grays)) a. Adjust sRGB (9300K) color-temperature 1. Switch the Chroma-C7120 to RGB-mode (with press “MODE” button) 2. Switch the MEM.channel to Channel 0 (with up or down arrow on Chroma-C7120) 3.The LCD-indicator on Minolta-CA210 will show x = 283 ±12, y = 297±12 b.
5.2 Firmware Upgrade Procedure 5.2.
Hardware Connect status 5.2.2 Update the NOVATEK’S firmware You should jump the pin to “For Flash” at ISP Board Connect to the PC LPT Connect to the VSC VX2413wm-2 Double click “Writer.
This tool can auto detect the right SCALAR programe speed,the process as follow: When auto detect is finished,click “Load Hex”,then chosse the firmware that you want to update 25
Click “Auto”,then the update will begin.Wait for a moment until the bar is 100%,the program windows will show “Programing Success”.This means the update is successful. 5.3 DDC Key in Procedure Note: 1. Every time after replacing the main board, you have to do the DDC key in. 2. If you find the DDC does not conform to the LCD TV, you have to do the DDC key in. 5.3.1 Equipment Needed - VX2413wm-2 - PC (Personal computer) - LPT cable - 12V DC - Firmware upgrade program - DDC Card 5.3.
