2. Clock adjustment
Set the Chroma at pattern 63 (cross-talk pattern) or WIN 9 8 / 95 sh ut - 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)

3. Focus adjustment
Set the Chroma at pattern 63 (cross talk pattern) or WIN98 / 95 sh ut do w n 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

4. 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.

5. 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)

6. 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.

7. 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.

**Note : the Waveform of U304 pin 2 can determined the power situation

1. stable rectangle waveform with equal duty, freq aroun d 150 K- 1 58 K Hz

that means all power of this interface board is in normal operation
,and all status of 5V & 3.3V is working well

2. unstable or uneven rectangle waveform without same duty, that means ABNORMAL operation was

happened, check 3.3V or 5V ,if short-circuit or ba d component

3. rectangle waveform with large spike & harmonic pulse on front side , means all 3.3v is no load, U200

Gmzan2 was shut- down, and only U302 MCU still working , that means the monitor is in power saving
status , all power system is working well .

Measure input power at U304 LM2596 pin 1=
12V ?

NG

Check ADAPTER and connector if loose?

Check U304 pin 2 is a stable rectangle wave?
Around 150k-158kHz stable rectangle wave
with equal duty without any spike or harmonic
pulse?

The interface board power is good

NG

Check U304 pin 2 is a unstable rectangle wave ?

OK, unstable wave

Check all 3.3V & 5V power, there is
short circuit or bad component was
happened

NG, with
harmonic

ulse

The interface board is in power­saving state, press power key to wake
up & check your signal input

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 ??

Adjust “FOCUS” step by step, until the
horizontal interferences disappear

Does your signal-cable have an additional
cable for extension ??

Does your noise only exist in one mode only?
(ex: only at 1280x1024 @ 75 Hz, other is normal)

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

NO additional extension cable

Yes, only happened on one mode

Yes, has extension

END

END

Put away the additional cable
May be the additional cable grounding is
not quite well

Change the Signal-cable to new-one or
Try other brand VGA-CARD
(make sure just only that brand VGA­CARD has this problem ,contact RD-
Tai

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

If the Y less than 200 cd/m2 (after the contrast,
brightness = max) then change the LAMP of panel

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,

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
