The input mode may change in the following cases:

- When video play is stopped with a playback device.
Power LED flashes red.
“STATUS [xxxx]” appears in the corner of the screen.
• Hardware has a problem. Turn off the monitor and request
repair from your SHARP dealer.
(When STATUS ALERT is set to OSD & LED. This varies
depending on the setting.)
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

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.
