Power Issues

If your screen does not display a picture, be sure thar power connection from the power source to the AC input terminal on the left of the screen in the back connects well.

Accidental Standby Mode

Sharp monitors have a feature named Adjusment Lock which allows you to disable the power switch. Press your remote control unit’s Size button for about five seconds and Access this feature. Then press Right to view the on-screen menu which displays th Adjustment Lock Menu item. Press the menu’s arrow keys until the value next to that item changes to Off.

Rising Temperatures

When temperature changes, your monitor makes a crackling sound, and this noise is pretty normal. However, If you see the word Temperature on your screen and your monitor enters standbye mode, the power Led will flash green and red lights. If this happens, move your monitor away from everything which may covering its vents. If there is nothing blocking the vents, turn the power switch off and back on again. Also, dust which exist inside of the monitor may cause overheating. If you suspect that dust may be the problem here, contact your Sharp representative for instructions to remove the dust. High temperatures may also be the cause of the monitor’s brightness to decrease and the words “Auto Dimming” to appear on the screen.

Incorrect Input Mode

Sharp LCD monitors usually have many sockets into which you can connect external devices.
