The computer input image
looks strange
Check the following:
• Have you chosen an unsupported output resolution on the
"List of Video Input Signals Supported by
to select a supported resolution
and try again.
• Use the
Auto Adjustment
function (
) to let the display automatically optimize the
display of computer image.
• If the result of the
Auto Adjustment
function is not
satisfactory, use the
Clock Frequency
,
Phase
,
H. Position
and
V. Position
functions to manually adjust the image.
• Reconnect the cable again, and then check that the cable is
connected correctly.
• Save changes to a file you are working on, and then quickly
press and release the power button on the front side of the
display. When the machine shuts down, press the power
button again to restart the machine.
If any of these actions do not fix the problem, contact your
service representative.
The control panel buttons
do not work
When a controller designed compliant with OPS (Open
Pluggable Specification) standard is connected to the machine,
the control panel buttons will not work until the controller is
completely shut down. Wait until shutdown is complete.
The remote control does
not work
• Check for incorrect battery orientation.
• Check for dead batteries.
• Check your distance and angle from the machine.
• Check whether remote control is properly being pointed at
the remote control sensor window of the display.
• Check for any obstacle between the remote control and the
remote control sensor window.
• Check that the remote control sensor window is not under
strong fluorescent lighting, or in direct sunlight.
• Check for any devices (computer or personal digital
assistant, PDA) nearby that transmit infrared signals which
may cause interference to signal transmission between the
remote control and the machine. Turn off the infrared function
of these devices.
An abnormal sound is
heard from the area
surrounding the output/
input terminals on the back
of the display
Quickly press and release the main power button on the back
of the display. When the machine shuts down, press the main
power button again to restart the machine. If any of these
actions do not fix the problem, contact your service
representative.
