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 10.)

•Is the main power switch off? (See page 13.)

•Is the monitor in standby mode (the power LED illuminating in orange)? (See page 13.)

•Make sure correct input mode is selected. (See page 14.)

•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 12.)

•Are the batteries exhausted?

•Point the remote control unit toward the monitor’s remote control sensor. (See page 12.)

•Is the menu display hidden or is operation disabled? (See page 21.)

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

•Are audio cables connected properly? (See pages 9.)

•Check the setting of BALANCE for AUDIO menu. (See page 18.)

There is no sound.

•Is the sound muted?

•Make sure the volume is not set to minimum.

•Are audio cables connected properly?

•When a video signal is not input, sound is not output.

Unstable video.

•The signal may be incompatible.

•Try the automatic screen adjustment when the PC D-sub input terminal is used.

The video from the PC/AV 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 pages

29 and 30.)

The video from the PC/AV DVI-D input terminal does not appear properly.

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

29 and 30.)

•Turn off the power to the connected equipment and then turn the power on again.

The video from the AV COMPONENT input terminal does not appear properly.

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

30.)

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.

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 5.)

-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.
