Troubleshooting
Warning when temperature rises
• 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 fl ashes red and
green alternately.
• If the internal temperature rises further, the monitor automatically enters standby mode. (The Power
LED continues fl ashing red and green alternately.)
Solution:
• If the monitor enters standby mode due to a rise in temperature, to return to normal display, turn the
main 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 10.)
• 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 monitor sometimes makes a cracking sound.
• You may hear 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.
