If you are experiencing any problem with your display, before 
calling for service, please review the following troubleshooting 
tips.
There is no picture or sound.

•  Is the power cord disconnected? (See page 14.)
•  Is the main power switch off? (See page 17.)
•  Is the monitor in standby mode (the power LED illuminating

in orange)? (See page 17.)

•  Make sure correct input mode is selected. (See page 19.)
•  If any external equipment is connected, make sure the

equipment is operating (playing back).

•  Are the batteries inserted with polarity (+,-) aligned? (See

page 16.)

•  Are the batteries exhausted?
•  Point the remote control unit toward the monitor’s remote

control sensor. (See page 16.)

•  Is operation disabled? (See page 28.)

•  Are audio cables connected properly?

•  Is the sound muted?
•  Make sure the volume is not set to minimum.
•  Are audio cables connected properly?
•  Is AUDIO OUTPUT or SPEAKER correctly set on the

SETUP menu? (See page 27.)

•  The signal may be incompatible.

•  Is the HDMI cable HDMI standard compliant? The monitor

will not work with cables that are not standard compliant.

•  Is the input signal compatible with this monitor? (See page

45.)

•  If an AV signal such as 1920 x 1080i, 720(1440) x 576i, or

720 (1440) x 480i is displayed using the HDMI[PC] input,
display problems such as faint colors may occur. Display
using HDMI[AV].

•  Is the input signal compatible with this monitor? (See page

45.)

•  Turn off the power to the connected equipment and then

turn the power on again.

•  If the monitors are connected in a daisy chain, turn off the

power to all the monitors connected in a daisy chain and 
then turn the power on again.

•  If an AV signal such as 1920 x 1080i, 720(1440) x 576i,

or 720 (1440) x 480i is displayed using the DVI-D input,
display problems such as faint colors may occur. Display
using HDMI[AV], D-SUB[COMPONENT] or D-SUB[VIDEO].

•  Is the input signal compatible with this monitor? (See page

45.)

•  Load noises from outside may be interfering with normal

operation. Turn off the power and turn it on after waiting at
least 5 seconds, and then check the operation.

•  You may occasionally hear a cracking sound from the

monitor. This happens when the cabinet slightly expands
and contracts according to change in temperature. This
does not affect the monitor’s performance.

•  When a USB flash drive is connected, it is better to turn

the power ON/OFF using the remote control unit. When
the power is turned ON using the main power switch with
a USB flash drive connected, the monitor startup takes
a longer time because the monitor checks USB terminal
connection after checking other terminal connections.

•  Is the file in a supported format? (See page 21.) 

The following problems may occur if a non-supported
format is used: 
- The file does not play properly. 
- Pausing or Move forward/back cannot be performed 
during playback. 
- Abnormal play speed 
- Operations cannot be performed during playback 
- Playback stops. The player application restarts.

•  The screen will turn black if none of the files in the play list

are in the USB flash drive. Press

INPUT

 to exit.
