vijipakki, You or technician will need to look for bad capacitors (tops of them swollen) on the "switch-mode-power-supply" circuit board. What is correct model number of your unit and the "date of manufacture" from rear of unit?? click on "comment" to leave a reply. 12fixlouie

You may have problem in the logic board (the right board in the first picture), bad firmware in the ROM chip, which there is not much you can do to reload the firmware. You can open it up and inspect the inside.

Choose the auto adjust option

There might be dirt underneath or close to the buttons.Try some compressed air to remove any dirt that might be there.Remember to unplug the monitor before you try to service it.
Good Luck

Hi,
This problem is usually caused due to a faulty microswitch in the brightness button. To rectify this, you'll have to change this switch.
Get your monitor serviced by a qualified service personnel.
Hope this solves your problem. For more help or clarifications, please reply. Thanks.

buy a new monitor.....that one is broken.

There has to be a menu for picture settings affecting contrast and brightness. Just be patient and you will find them.. Or go to sharp web page for manual download.

Hello,

Unfortunately, it soulds like the monitor may be going bad. You may have to use the manufacturer warranty if its still valid.

Thanks
