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 13.)
• 
  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 18.)
• 
  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 29.)
Sound from left and right speakers is reversed.
Sound is heard from only one side.
•   Are audio cables connected properly?
•  Check the setting of BALANCE for AUDIO menu. (See 
page 23.)
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 SETUP menu 
correct? (See page 23.)
Unstable video. •
  The signal may be incompatible.
•
  Try the automatic screen adjustment when the D-SUB is 
used.
The video from the HDMI input terminal does not appear 
properly. •
  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 
51.)
The video from the DVI-D input terminal does not appear 
properly. •
  Is the input signal compatible with this monitor? (See page 
51.)
•
  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 D-Sub input terminal does not appear 
properly.
•   Is the input signal compatible with this monitor? (See page 
51.)
The video from the DisplayPort does not appear properly. •   Is the input signal compatible with this monitor? (See page 
51.)
The video from component input terminals does not 
appear properly. •   Is the video cable (Y/Cb/Cr) connected correctly?
•   Is the input mode set to COMPONENT?  
The video will not appear correctly if the input mode is set 
to VIDEO.
The video from video input terminal does not appear 
properly. •   Is the input mode set to  VIDEO?  
The video will not appear correctly if the input mode is set 
to COMPONENT.
Control buttons do not work.
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 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. 
						

							
46E

The Power LED is flashing in red and green alternately.•    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, the Power LED flashes red 
and green alternately.
• 
  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 7.)
- 
  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.

When mounting the monitor, be sure to use a wall-mount bracket that complies with the VESA-compatible mounting method.  
SHARP recommends using M6 screws and tighten the screws.  
Note that screw hole depth of the monitor is 3/8 inch (10 mm). Loose mounting may cause the product to fall, resulting in 
serious personal injuries as well as damage to the product. The screw and hole should come together with over 5/16 inch   
(8 mm) length of thread. Use a bracket which has been approved for UL1678 standard, and which can endure at least 4 times 
or more the weight of the monitor.

The monitor supports the VESA DDC (Display Data Channel) standard.
DDC is a signal standard for plug and play between monitors and computers. Information about resolution and other parameters 
is exchanged between the two. This function can be used if the computer supports DDC and it has been configured to detect 
plug-and-play monitors.
There are several types of DDC, depending on the communication method used. 
This monitor supports DDC2B.
