Chapter 4 Troubleshooting
If a problem still remains after applying the suggested remedies, contact your local dealer .
•  No-picture problems → See No.1 - No.2.
•  Imaging problems → See No.3 - No.11.
•  Other problems → See No.12.
ProblemsPossible cause and remedy
1.	No picture
•  Power indicator does not light. • 
Check whether the power cord is connected correctly. If 
the problem persists, turn off the monitor, and then turn it 
on again a few minutes later.
•  Power indicator is lighting blue.
•  Power indicator is lighting orange. • 
Check Gain setting. (see 
page 15)
•  Operate the mouse or keyboard.
2.  The message below appears.
•  This message appears when no signal is input.
This message appears when the signal is not input correctly even when the monitor functions properly.
• The message shown left may appear, because some 
PCs do not output the signal soon after power-on.
•  Check whether the PC is turned on.
•  Check whether the signal cable is connected properly.
•  The message below shows that the input signal is 
out of the specified frequency range. (Such signal 
frequency is displayed in red.)
  Example:
• Select an appropriate display mode using the graphics 
board’s utility software. Refer to the manual of the 
graphics board for details.
3.   Display position is incorrect.
• Adjust image position so that it is displayed properly 
within the display area using the   and 
  adjustment.
•  If the problem persists, use the graphics board’s utility 
software if available to change the display position.
4.  Vertical bars appear on the screen or a part of the 
image is flickering.• Adjust using   from  menu at the Adjustment menu.
5.  Whole screen is flickering or blurring.
• Adjust using  .
.  The screen is too bright or too dark.
• Adjust 
 . (The LCD monitor backlight has a fixed life span. When the screen becomes dark or 
begins to flicker, contact your local dealer.)
7.  Afterimages appear. • Use a screen saver or off timer function for a long-time 
image display.
•  Afterimages are particular to LCD monitors. Avoid 
displaying the same image for a long time.
 
						

							
21Chapter 4  Troubleshooting
ProblemsPossible cause and remedy
8.  Green/red/blue/white dots or defective dots remain 
on the screen. • 
This is due to LCD panel characteristics and is not a failure.
9.  Interference patterns or fingerprints remain on the 
screen. • 
Leave the monitor with a white screen. The symptom may disappear.
10.  The Main menu of Adjustment menu does not start. • Check for Adjustment Lock function.
11.  The auto-adjustment function does not work 
correctly. • 
This function does not work when digital signal is input.
•  This function works correctly when an image is fully 
displayed over the Windows or Macintosh display area. 
It does not work properly when an image is displayed 
only on a part of the screen (DOS prompt window, for 
example) or when a black background (wallpaper, etc.) is 
in use. 
This function does not work correctly with some graphics 
boards.
12.  No audio output*
1• Check whether  is set to “0”.
•  Check the settings of the PC and the audio playback 
software.

5-4 Glossary
Clock
The analog input monitor needs to reproduce a clock of the same frequency as the dot clock of the graphics system in 
use, when the analog input signal is converted to a digital signal for image display . 
This is called clock adjustment. If the clock pulse is not set correctly, some vertical bars appear on the screen.
DVI (Digital Visual Interface)
DVI is a digital interface standard. DVI allows direct transmission of the PC’ s digital data without loss.
This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors. One is 
a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital and analog signal 
inputs.
DVI DMPM (DVI Digital Monitor Power Management)
DVI DMPM is a digital interface power-saving function. The “Monitor ON (operating mode)” and “Active Off 
(power-saving mode)” are indispensable for DVI DMPM as the monitor’s power mode.
Gain
This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the color by the light 
passing through the panel color filter. Red, green and blue are the three primary colors. All the colors on the screen 
are displayed by combining these three colors. The color tone can be changed by adjusting the light intensity (volume) 
passing through each color’s filter.
Phase
Phase means the sampling timing to convert the analog input signal to a digital signal. Phase adjustment is made to 
adjust the timing. It is recommended that phase adjustment be made after the clock is adjusted correctly .
Resolution
The LCD panel consists of numerous pixels of specified size, which are illuminated to form images. The monitor 
consists of 1280 horizontal pixels and 1024 vertical pixels. At a resolution of 1280 × 1024, all pixels are illuminated 
as a full screen (1:1).
sRGB (Standard RGB)
International	standard	for	“color	reproduction	and	color	space”	among	peripheral	devices	(such	as	monitors,	printers,	
digital cameras, scanners). sRGB allows Internet users to closely match colors as a simple color matching means for 
the Internet use.
Temperature
Color temperature is a method to measure the white color tone, generally indicated in degrees Kelvin.  The screen 
becomes reddish at a low temperature, and bluish at a high temperature, like the flame temperature.
5000K:	Slightly	reddish	white
6500K:	Warm	white	like	paper	white
9300K:	Slightly	bluish	white
TMDS (Transition Minimized Differential Signaling)
A signal transmission system for digital interface.
VESA DPMS (Video Electronics Standards Association - Display Power Management Signaling)
VESA provides the standardization of signals from PC (graphics board) for power saving of PC monitors. DPMS 
defines the signal status between PC and monitor.

a)  Der Standfuß muß eine ausreichende mechanische Stabilität zur Aufnahme des Gewichtes vom Bildschirmgerät 
und  des  spezifizierten  Zubehörs  besitzen.  Das  Gewicht  des  Bildschirmgerätes  und  des  Zubehörs  sind  in  der 
zugehörenden Bedienungsanleitung angegeben.
b)  Die Befestigung des Standfusses muß derart erfolgen, daß die oberste Zeile der Bildschirmanzeige nicht höher 
als die Augenhöhe eines Benutzers in sitzender Position ist.
c)  Im Fall eines stehenden Benutzers muß die Befestigung des Bildschirmgerätes derart erfolgen, daß die Höhe der 
Bildschirmmitte über dem Boden zwischen 135 – 150 cm beträgt.
d)  Der Standfuß muß die Möglichkeit zur Neigung des Bildschirmgerätes besitzen (max. vorwärts: 5°, min. nach 
hinten ≥ 5°).
