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.
After the Power LED illuminates in red and blue
alternately, the monitor automatically turns off, and the
Power LED illuminates in red.
• Whentheinternaltemperatureofthemonitorrises
excessively, the monitor automatically will turn off.
• Removethecauseoftheexcessivetemperaturerise.
- If the monitor enters standby state 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 state 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.
