Troubleshooting
The Power LED is flashing in red and green alternately.
When "AUTO DIMMING" 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, "AUTO DIMMING" is
displayed on the screen and 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.
The inner side of the glass is cloudy.
• When the humidity is high, the inner side of the glass
may cloud after the power is turned on. The cloudiness is
caused by the difference between the ambient temperature
and the temperature of the air inside the glass, and is
not a malfunction. You can continue to use the monitor to
disappear the cloudiness.
