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.
