You can control the monitor using RS-232C commands 

(see page 36) via terminal software and other appropriate 

applications.

In order to use this function, enable a connection to the 

monitor through Internet Explorer.

Read the manual for the terminal software for detailed 

instructions.

1.  Specify the IP address and data port number and 

connect the PC to the monitor. 

When connection has been established successfully, 

[ Login:] is returned as response.

2.  Send the user name set in the SECURITY settings (see 

page 49).

•  Send [User name] + [ ].

•  If the user name is not set, send [ ].

•  When the transmission is successful, [ Password:] 

is returned as response.

3.  Send the password set in the SECURITY settings (see 

page 49).

•  Send [Password] + [ ].

•  If the password is not set, send [ ].

•  When the transmission is successful, [OK  ] is 

returned as response.

•  The commands used are the same as those for RS-

232C. Refer to the communication procedure (see 

page 33) for operation.

•  Usable commands are provided in the RS-232C 

command table (see page 37).

1.  Send [BYE ]. 

When the transmission is successful, [goodbye] is 

returned and the connection is disconnected.

TIPS

•  Connection is automatically disconnected when the 

time specified in AUTO LOGOUT TIME elapses over a 

no-communication period.

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).

•  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 32.)

•  Are audio cables connected properly?
•  Check the setting of BALANCE for AUDIO menu. (See 

page 24.)

•  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 24.)

•  The signal may be incompatible.
•  Try the automatic screen adjustment when the 

D-SUB[RGB] or DVI-I (analog) are used.

•  Is the setting for HDMI1 or HDMI2 of INPUT SELECT on 

the SETUP menu correct? (See page 24.)

•  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 

59.)

•  Is the setting for EDID SELECT (DVI-I) of INPUT SELECT 

on the SETUP menu correct? (See page 24.)

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

59.)

•  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 D-SUB of INPUT SELECT on the SETUP 

menu correct? (See page 24.)

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

59.)

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

59.)

•  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.

•   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.)

•   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.

•   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.

55

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 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 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.
