Troubleshooting
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 16.)
•  Is the monitor in standby mode (the power LED illuminating
in orange)? (See page 16.)
•  Make sure correct input mode is selected. (See page 21.)
•  If any external equipment is connected, make sure the
equipment is operating (playing back).
Remote control does not work.
•  Are the batteries inserted with polarity (+,-) aligned? (See
page 15.)
•  Are the batteries exhausted?
•  Point the remote control unit toward the monitor’s remote
control sensor. (See page 15.)
•  Is the menu display hidden or is operation disabled? (See
page 31.)
Sound from left and right speakers is reversed.
Sound is heard from only one side.
•  Are audio cables connected properly? (See pages 12 to
13.)
•  Make sure audio cables for external speakers are
connected properly: left and right cables may be reversed 
or one of the two cables may not be connected. (See page
13.)
•  Check the setting of BALANCE for AUDIO menu. (See
page 25.)
There is a picture but no sound.
•  Is the sound muted?
•  Make sure the volume is not set to minimum.
•  Are audio cables connected properly?
•  Is the setting of AUDIO SELECT on the OPTION menu
correct? (See page 26.)
•  Is the setting of SPEAKER SELECT on the SETUP menu
correct? (See page 26.)
Unstable video.
•  The signal may be incompatible.
•  Try the automatic screen adjustment when the PC D-sub
input terminal or PC RGB input terminals are used.
•  If the top and bottom of the image are not horizontally
aligned, set TOUCH PANEL MODE on the OPTION menu
to OFF.
The video from the PC/AV HDMI input terminal does not 
appear properly.
•  Is the setting for HDMI of INPUT SELECT on the OPTION
menu correct? (See page 26.)
•  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
55.)
The video from the PC/AV DVI-D input terminal does not 
appear properly.
•  Is the setting for DVI of INPUT SELECT on the OPTION
menu correct? (See page 26.)
•  Is the input signal compatible with this monitor? (See page
55.)
•  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.
The video from PC D-SUB, PC RGB, AV COMPONENT, or 
AV VIDEO does not appear correctly.

There is no picture.
•  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.
The input mode changes automatically.
•  When the AUTO INPUT CHANGE is ON and no signal
is present in a selected input mode, the AUTO INPUT 
CHANGE automatically changes the selected mode to a
mode where a video signal is present.
  The input mode may change in the following cases:
- When a computer is in standby mode.
- When video play is stopped with a playback device.
The touch panel does not respond.
•  Is the USB cable connected properly? (Touch Panel Driver
Operation Manual)
•  Has the touch panel driver been installed? (Touch Panel
Driver Operation Manual)
•  Has the pen tip of the touch pen become worn? Replace
the pen tip. (See page 20.)
•  Is the battery inserted in the wrong orientation (+, -) in the
touch pen? (See page 18.)
•  Is the touch pen battery exhausted?
The response of the touch screen is slow.
Some parts of the screen do not respond.
•  Is the screen exposed to direct sunlight or other strong
light? The touch panel uses infrared rays and thus may not 
operate correctly.
•  Is there an obstacle between the infrared transmitter/
receiver and the touch pen or your finger? An obstacle
will prevent correct operation. If your fingers or a sleeve
are too close to the screen, correct operation will not be 
possible.
•  Is the infrared transmitter/receiver dirty? Gently wipe off
any dirt with a soft cloth.
•  If the touch panel is touched with a small tip less than about
3/16 inch (4 mm) x 3/16 inch (4 mm), the touch may not
be detected by infrared and correct operation will not take 
place.
•  When starting your computer or connecting the USB cable,
do not touch the touch panel. If you touch the touch panel, 
this may be detected as an element failure in the infrared 
transmitter/receiver and incorrect operation will result.
Power LED flashes red.
“STATUS [xxxx]” appears in the corner of the screen.
•  Hardware has a problem. Turn off the monitor and request
repair from your SHARP dealer. 
(When STATUS ALERT is set to OSD & LED. This varies
depending on the setting.)
The touch panel power LED lights red.
•  Hardware has a problem. Turn off the monitor and request
repair from your SHARP dealer.

When “AUTO DIMMING” is displayed.
•  When the internal temperature of the monitor rises
excessively, the brightness of the backlight automatically 
decreases in order to prevent a further temperature rise. If 
you attempt to use 
 
to adjust the brightness while
the monitor is in this state, “AUTO DIMMING” is displayed
and you cannot change the brightness.
•  Remove the cause of the excessive temperature rise.
The monitor makes a cracking sound.
•  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.
The Power LED is flashing in red and green alternately. 
When “TEMPERATURE” is displayed in the corner of the 
screen.
•  When the internal temperature of the monitor rises
excessively, the brightness of the backlight decreases 
automatically in order to prevent high-temperature-
related problems. When this occurs, “TEMPERATURE” is
displayed on the screen and the Power LED flashes red
and green alternately. (When TEMPERATURE ALERT is
set to OSD & LED. This varies depending on the setting.)
•  If the internal temperature rises further, the monitor
automatically enters standby mode. (The Power LED
continues flashing red and green alternately.)
•  Remove the cause of the excessive temperature rise.
- If the monitor enters standby mode due to a rise in
temperature, to return to normal display, turn the power 
switch off and then back on again. The monitor, however, 
will enter standby mode again if the cause of the 
temperature rise is not eliminated. (See page 8.)
- Check whether the monitor is placed at a location where
a quick rise in temperature is likely. Internal temperature
rises quickly if the vents on the monitor are blocked.
- Internal temperature rises quickly if dust accumulates
inside the monitor or around the vents. Remove dust if 
possible. Ask SHARP dealer about removing internal dust.
