•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 16.)

•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 23.)

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

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

32.)

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 touch panel does not respond.

•Is the USB cable connected properly? (Touch Panel Driver

Operation Manual)

•Has the touch panel driver been installed? (Touch Panel

Driver Operation Manual)

•If you press hard on the monitor or apply force to the sensor area, sensor correction processing will take place.

During this time (several tens of seconds), the touch panel will not respond.

The response of the touch screen is slow.

Some parts of the screen do not respond.

•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 your finger? An obstacle will prevent correct operation.

•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 1/4 inch (7 mm) x 1/4 inch (7 mm), the touch may not be detected and correct operation will not take place.

•When starting your computer or connecting the USB cable, do not touch the touch panel.

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.
