THIN HORIZONTAL LINE
The lines that appear on your screen are damper wires. See 
page 15 for more information about the damper wires.
DISTORTED SHAPE
If the shape of the picture on the screen seems distorted, try 
adjusting the picture’s geometry. Move the control button , to 
jump directly to the GEOMETRY menu.
OUT OF FOCUS
The picture may seem to be out of focus when the red and blue 
color signals are not aligned properly, causing red or blue 
shadows to appear around letters and lines. Try adjusting the 
picture’s convergence to make the shadows disappear. Move the 
control button , to jump directly to the CONVERGENCE 
menu. When the CONVERGNECE menu is displayed, the 
contrast, brightness and moire adjustment settings are 
automatically reset for all input signals.
DISCOLORATION
If the picture’s color appears abnormal in certain areas of the 
screen, first check for any loose signal cables. After you have 
checked the cables, try degaussing (demagnetizing) the screen 
manually. Move the control button , to jump directly to the 
OPTION menu, then select 
 (DEGAUSS).

Technical Features
Preset and user modes
When the monitor receives an input signal, it automatically 
matches the signal to one of the factory preset modes stored in the 
monitor’s memory to provide a high quality picture at the center of 
the screen. (See Appendix for a list of the factory preset modes.) 
For input signals that do not match one of the factory preset 
modes, the digital Multiscan technology of this monitor ensures 
that a clear picture appears on the screen for any timing in the 
monitor’s frequency range (horizontal: 30 – 96 kHz, vertical: 48 – 
120 Hz). If the picture is adjusted, the adjustment data is stored as 
a user mode and automatically recalled whenever the same input 
signal is received.
Note for Windows users
For Windows users, check your video board manual or the utility 
program which comes with your graphic board and select the 
highest available refresh rate to maximize monitor performance.
Power saving function
This monitor meets the power-saving guidelines set by VESA, 
E
NERGY 
S
TAR, and NUTEK. If the monitor is connected to a 
computer or video graphics board that is DPMS (Display Power 
Management Signaling) compliant, the monitor will automatically 
reduce power consumption in three stages as shown below.
*
“Sleep” and “deep sleep” are power saving modes defined by the 
Environmental Protection Agency.
** When your computer is in a power saving mode, MONITOR IS IN 
POWER SAVE MODE appears on the screen if you press any button 
on the monitor. After a few seconds, the monitor enters the power 
saving mode again.
Troubleshooting
Before contacting technical support, refer to this section.
If thin lines appear on your screen 
(damper wires)
The lines you are experiencing on your screen are normal for the 
Trinitron monitor and are not a malfunction. These are shadows 
from the damper wires used to stabilize the aperture grille and are 
most noticeable when the screen’s background is light (usually 
white). The aperture grille is the essential element that makes a 
Trinitron picture tube unique by allowing more light to reach the 
screen, resulting in a brighter, more detailed picture.
On-screen messages
If no picture appears on the screen, one of the following messages 
appears on the screen. To solve the problem, see “Trouble 
symptoms and remedies” on page 16.   
The input signal condition
OUT OF SCAN RANGE
indicates that the input signal is not supported by the monitor’s 
specifications.
NO INPUT SIGNAL
indicates that no signal is input.
MONITOR IS IN POWER SAVE MODE
indicates that the computer is in power saving mode. This 
message is displayed only when your computer is in a power 
saving mode and you press any one of the buttons on the monitor.
