The input mode changes automatically.

• When the AUTO INPUT CHANGE is ON and no signal

CHANGE automatically changes the selected mode to a
mode where a video signal is present.

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

to adjust the brightness while

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.
