Troubleshooting
Causes and Solutions
Check the power switch, as there is a possibility that it is not
turned on.
Check the power cord, as there is a possibility that it is not
properly connected.
Check using a different device whether power is properly
supplied to the power outlet.
If the power cord is connected to the outlet on the
computer’s body, it may be possible that the power of the
computer is not turned on. Check whether the power of the
computer is turned on.
Check the LED Brightness Control function, as there are
cases where the LED does not light up if the brightness is
lowered.
Display the OSD Screen and check the following
items:
• If the OSD Screen cannot be displayed, it is possible that
there is a malfunction.
Consult with the dealer or the Repair Consultation Service.
• If the OSD Screen is displayed under normal conditions,
there is no malfunction. Adjust [BRIGHTNESS] and
[CONTRAST] in [PICTURE SETTINGS].
• If the computer screen is not displayed even when the
OSD Screen is properly displayed and you have adjusted
[BRIGHTNESS] and [CONTRAST], check the connection
with the computer, as well as the computer’s frequency,
resolution, and type of output signal.
If an HDCP-compliant device is connected and the screen is
not displayed, turn off the power of the connected device
and then turn it back on again.
The Power Management function may be in operation.
Press any key on the keyboard or move the mouse.
Check the signal cable, as there is a possibility that it is not
properly connected to the monitor or the computer’s socket.
Check the conversion adapter, as there is a possibility that
it is not properly connected.
Check the computer’s power, as there is a possibility that it
is not turned on.
A replacement with a new LCD panel is necessary.
Consult with the dealer or the [Repair Consultation Service].
