Troubleshooting
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 ashing in orange and blue alternately.
When “AUTO DIMMING” is displayed.
• 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 ashes orange
and blue alternately.
• If the internal temperature rises further, the monitor
automatically enters standby mode. (The Power LED
continues ashing orange and blue 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.
