2-1 ASSEMBLY PRECAUTION (1) Please do not press or scratch LCD panel surface with anything hard. And do not soil LCD panel surface by touching with bare hands ( Polarizer film, surface of LCD panel is easy to be flawed) In the LCD panel, the gap between two glass plates is kept perfectly even to maintain display characteristic and reliability. If this panel is subject to hard pressing, the following occurs : (a) Uniform color (b) Orientation of liquid crystal becomes disorder (2) Please wipe out LCD panel surface with absorbent cotton or soft cloth in case of it being soiled. (3) Please wipe out drops of adhesive like saliva and water in LCD panel surface immediately. They might damage to cause panel surface variation and color change. (4) Do not apply any strong mechanical shock to the LCD panel. 2-2 OPERATING PRECAUTIONS (1) Please be sure to unplug the power cord before remove the back-cover. (be sure the power is turn-off) (2) Please do not change variable resistance settings in MAIN-BOARD, they are adjusted to the most suitable value. If they are changed, it might happen LUMINANCE does not satisfy the white balance spec. (3) Please consider that LCD backlight takes longer time to become stable of radiation characteristic in low temperature than in room temperature. (4) Please pay attention to displaying the same pattern for very long-time. Image might stick on LCD. 2-3 STORAGE PRECAUTIONS (1) When you store LCD for a long time, it is recommended to keep the temperature between 5-40 without the exposure of sunlight and to keep the humidity less than 85% RH. (2) Please do not leave the LCD in the environment of high humidity and high temperature such as 60 90%RH.

Clock adjustment Set the Chroma at pattern 63 (cross-talk pattern) or WIN98/95 shut-down mode (dot-pattern). Adjust until the vertical-Stripe-shadow as wide as possible or no visible. This function is adjust the PLL divider of ADC to generate an accurate pixel clock Example : Hsyn = 31.5KHz Pixel freq. = 25.175MHz (from VESA spec) The Divider number is (N) = (Pixel freq. x 1000)/Hsyn From this formula, we get the Divider number, if we fill this number in ADC register (divider register), the PLL of ADC will generate a clock which have same period with above Pixel freq.(25.175MHz) the accuracy of this clock will effect the size of screen.(this clock was called PIXEL-CLOCK) Focus adjustment Set the Chroma at pattern 63 (cross talk pattern) or WIN98/95 shut down mode (dot-pattern). Adjust the horizontal interference as less as possible This function is adjust the phase shift of PIXEL-CLOCK to acquire the right pixel data . If the relationship of pixel data and pixel clock not so match, we will see the horizontal interference on screen ,we only find this phenomena in crosstalk pattern or dot pattern , other pattern the affect is very light H/V-Position adjustment Set the Chroma to pattern 1 (crosshatch pattern) or WIN98/95 full-white pattern confirm above item 2 & 3 functions (clock & focus) was done well, if that 2 functions failed, the H/V position will be failed too. Adjust the four edge until all four-edges are visible at the edge of screen. LANGUAGE function There have 5 language for selection, press "MENU" to selected and confirm , press " LEFT" or " RIGHT" to change the kind of language ( English , Deutch , Francais, Espanol, Italian) Reset function Clear each old status of auto-configuration and re-do auto-configuration ( for all mode) This function also recall C2 color-temperature , if the monitor status was in " Factory-mode" this reset function will clear Power-on counter ( backlight counter) too. OSD-LOCK function Press Left & Right key during switching on the monitor, the access to the OSD is locked, user only has access to " Contrast, Brightness, Auto-key ". If the operator pressed the Left & Right during switching on the monitor again , the OSD is unlocked.

The interface board is in powersaving state, press power key to wake up & check your signal input
18
III.ALL SCREEN HAS INTERFERENCES OR NOISE, CAN'T BE FIXED BY AUTO KEY
** NOTE: There is so many kind of interferences, 1). One is cause by some VGA-CARD that not meet VESA spec or power grounding too bad that influence our circuit 2).other is cause by external interferences, move the monitor far from electronic equipment.( rarely happened) Use DOT-pattern, or win98/99 shut-down mode pattern, press "AUTO" key, was the interferences disappear ?? NG, interferences still exist Adjust "FOCUS" step by step, until the horizontal interferences disappear OK END
OK
END
NG Does your signal-cable have an additional cable for extension ?? Yes, has extension Put away the additional cable May be the additional cable grounding is not quite well
NO additional extension cable Does your noise only exist in one mode only? (ex: only at 1280x1024 @ 75 Hz, other is normal) NO, all mode Change the Signal-cable to new-one or Try other brand VGA-CARD (make sure just only that brand VGACARD has this problem ,contact RDTaipei)
Yes, only happened on one mode That was cause by you VGA-CARD setting, your VGA card timing back porch / front porch exceed vesa timing too far, for some new AGP-VGA-CARD such situation always happened So in your control-panel icon ,select monitor ,setting , advance ,screen-adjust ,at Size icon, increase step by step slowly, press ""AUTO" key every step you increase the SIZE . repeat the procedure( increase/decrease SIZE one-step and press AUTO) until the interferences disappear, press "APPLY" to save in your VGA
19
There is interferences in DOS MODE
NOTE :the criteria of doing AUTO-CONFIGURATION : must be a full-size screen, if the screen not full , the autoconfiguration will fail. So in dos mode ,just set your "CLOCK" in OSD-MENU to zero or use some EDITOR software which can full fill the whole screen (ex: PE2, HE) and then press "AUTO" Or you can use "DOS1.EXE" which attached in your Driver disk to optimize DOS mode performance
V. THE PANEL LUMINANCE WAS DOWN
Use white pattern and resolution 1280x1024 @ 60Hz , CHROMA 7120 measured the center of panel
Set Contrast, brightness =maximal, RGB= 50 Quit from OSD-screen, measured Y(luminance) With chroma 7120, check Y= 240±10 cd/m2 ?
If Y can reach 240 cd/m2 that means The lamp still working well, so we just re-do the white-balance process As following procedure
OK NG Use white-pattern, press MENU button along with AC power-plug in ( you will in factory mode) The OSD-menu will be at left-top of screen,
OK
If the Y less than 200 cd/m2 (after the contrast, brightness = max) then change the LAMP of panel
press AUTO button to automatically adjust black level value, you will see the sign PASS
Follow White-Balance, Luminance adjustment as above ( page 8),method to more detail procedure For do a white-balance adjust
