Troubleshooting your Sharp TV has no difference from troubleshooting any other television. You just need to identify the source of the problem and fix this problem. The basic procedures are the same procedures for most TV. However, Sharp TV has a unique configuration for its televisions which allow you to access them.
Before you begin, be familiar with the buttons of the Sharp remote control. Especially pay attention to the Menu button which has access the more practical settings.
|No power.||Turn on (I) the MAIN POWER switch on the left side of the TV|
|Check if you pressed ON/OFF on the remote control unit. If the indicator on the TV lights up red, press ON/OFF.|
|Is the AC cord disconnected?|
|Check if you pressed ON/OFF on the TV.|
|The TV cannot be operated.||External influences such as lightning, static electricity, etc., may cause improper operation. In this case, operate the TV after first turning off the power, or unplugging the AC cord and re-plugging it in after one or two minutes.|
|Remote control unit does not operate.||Are batteries inserted with polarity (+,-) aligned?|
|Are batteries worn out? (Replace with new batteries.)|
|Are you using it under strong or fluorescent lighting?|
|Is a fluorescent light illuminating to the remote control sensor?|
|Picture is cut off.||Is the image position correct?|
|Are screen mode adjustments (WIDE MODE) such as picture size made correctly?|
|Strange colour, light colour, or dark colour, or colour misalignment.||Adjust the picture tone.|
|Is the room too bright? The picture may look dark in a room that is too bright.|
|Check the “Colour system” setting|
|Power is suddenly turned off.||The TV’s internal temperature has increased. Remove any objects blocking the vent or clean.|
|Is the “Sleep timer” set? Select “Off” from the “Sleep timer” menu|
|Is “No signal off” or “No operation off” activated?|
|No picture.||Are connections to external equipment correct?|
|Is the input signal type selected correctly after connection?|
|Is the correct input source selected?|
|Is a non-compatible signal being input?|
|Is the picture adjustment correct?|
|Is the antenna connected properly?|
|Is “On” selected in “Audio only”?|
|No sound.||Is the volume too low?|
|Make sure that headphones are not connected.|
|Check if you pressed MUTE on the remote control unit.|
|Is the proper item selected in the “PC audio select” menu when connecting devices to the HDMI 2 terminal or the EXT 4 terminal?|
|The TV sometimes makes a cracking sound.||This is not a malfunction. This happens when the cabinet slightly expands and contracts according to changes in temperature. This does not affect the TV’s performance.|
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.
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.
