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).

•  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.)

•  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.)

•  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.)

•  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.

•  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.)

•  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.

•  Is the setting for BNC or D-SUB of INPUT SELECT on the

OPTION menu correct? (See page 26.)

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

55.)

•  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.

•  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.

•  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?

•  Is the screen exposed to direct sunlight or other strong

light? Is a device that uses infrared being used nearby? 

The touch panel uses infrared rays and thus may not 

operate correctly.

•  Is there an obstacle between the sensor 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 reflective surface dirty? Gently wipe off any dirt with a

soft cloth.

•  If the touch panel is touched with a small tip less than about

3/8 inch (10 mm) x 3/8 inch (10 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.

•  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.)
