Before calling for repair services, make sure following checks for possible remedies to the encountered 
symptoms.

There is no picture or sound.

Remote control does not work.

Sound from left and right speakers is 
reversed.
Sound is heard from only one side.

There is a picture but no sound.

Faint colour or bad hue.

•  Is the power cord disconnected?
•  Is the main power switch set to “OFF (O)”?  
•  Is the monitor in standby mode (the power LED 

illuminating in orange)?

•  Make sure correct input mode is selected.
•  If any external equipment is connected, make 

sure the equipment is operating (playing back).

•  Are the batteries inserted with polarity (     ,     ) 

aligned?

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

remote control sensor.

•  Is the menu display hidden or is operation 

disabled?

•  Are audio cables connected properly?
•  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.

•  Check the setting of BALANCE for AUDIO.

•  Is the sound muted?
•  Make sure the volume is not set to minimum.
•  Is the PC audio cable (commercially available) 

connected?

•  Are audio cables connected properly?
•  Is the audio signal input properly to the audio 

input terminal corresponding to the selected video 
input terminal?

•  Check “COLORS” and “TINT” adjustments.
•  Make sure the connection sequence is correct.

•  The signal may be incompatible.
•  Try the automatic screen adjustment when the PC
  analogue RGB input terminal is used.

Some kind of load noises from outside might 
interfere with normal operation.
•  Turn off the power and turn it on after waiting at 

least 5 seconds, and then check the operation.

•  When the internal temperature of the monitor 

rises excessively, the brightness of the backlight 
decreases in order to prevent 
high-temperature-related problems. Remove the 
cause of the excessive rise in temperature.

When “TEMPERATURE” is displayed

48

E

•  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 fl ashes red and 

green alternately.

•  If the internal temperature rises further, the monitor automatically enters standby mode. (The Power 

LED continues fl ashing red and green alternately.)

 Solution:

•  If the monitor enters standby mode due to a rise in temperature, to return to normal display, turn the 

main 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 10.)

•  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.

The monitor sometimes makes a cracking sound.
•  You may hear 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.

Specifi cations

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 confi gured to detect plug-and-play monitors.
There are several types of DDC, depending on the communication method used. This monitor supports
DDC2B.
