The following are not malfunctions:
● You may see two horizontal lines on the monitor. They are the
shadows of the "damper lines" that are necessary for composing
the monitor. These lines are not a malfunction.
● About CRT tube reflection (when Zoom mode is used.)
The screen might appear as brownish white. This is due to a
reflection of part of the image on the CRT caused by certain
signal sources, and it is not a malfunction.
When black vertical lines appear on the screen
Black vertical lines may appear on the screen if the aperture grill is tilted as a result of being shaken or jolted during shipment.

In this case, try tapping the monitor on the side. If this does get rid of the lines, follow the procedure below.
1. Display a white screen, so that the problem area can be seen clearly.
2. Maximize the "CONTRAST" and "BRIGHT" adjustments, then place a bright white rectangle on the area.
3. After a while, the lines should disappear.

Measures (Remedy)
Move the device away from the monitor.
Press the DEGAUSS button on the front panel to
degauss the screen.
When degaussing, wait more than 30 minutes for
maximum effect.
Adjust the picture size (H. SIZE, V. SIZE) or
position (H. POSITION, V. POSITION) in the
[SIZE/POSI. ADJ.] item in the <SETUP MENU>
screen.
Adjust the picture distortion (PINCUSHION, PIN.
BALANCE, TRAPEZOID and PARALLELOGRAM)
in the [DISTORTION ADJ.] item in the <SETUP
MENU> screen.
It may not be possible to expand the picture due
to the selected input mode. In this case,
adjustment is impossible.
When the UNDER SCAN or ASPECT button is
lit, press each button to invalidate each setting.
Set the CONTROL LOCK function to OFF.
Change the setting of the external control to
control the monitor locally.
● When a bright still image (such as a white cloth) is displayed for a
long period, it may appear to be coloured. This is due to the
structure of the cathode ray tube and will disappear when another
image is displayed.
● You may sometimes experience a mild electric shock when you
touch the picture tube. This phenomenon is due to a normal
buildup of static electricity on the CRT and is not harmful.
● The monitor emits a strange sound when the room temperature
changes suddenly. This is only a problem if an abnormality
appears on the screen as well.
● If two or more monitors are operated next to each other, their
images may shake or be distorted. This phenomenon is due to
mutual interference; it is not a malfunction. Move the monitors
away from each other until the interference disappears or turn the
power off on any monitor that is not being used.
