Brightness bar stays in the center of my screen Samsung SyncMaster 731N


Hello,

I'm Adam and i'm a computer-technicien!

I should do these 2 things do hide this brightness bar:

-You can click the MENU button again!
-You can simply disconnect the power-cable from the monitor and
let it unplugged for like...10-15 seconds!
-You can remove the button with a screw-driver and take the
little plastic on the second button.

If this all doesn't work...
I can recommend you to send a email to SAMSUNG with this info:
-Name:
-Date when you bought this product:
-When did this start:
-And your CPU information:

If this all doesn't help...
You ned to install a driver called 'Syncmaster 720n/730n driver'!

Thank you,

My lcd samsung sync master 720n horizantaliy one line on screen


Hi

Please try the following

1) Degauss the monitor - this can be done by using the menu system on the monitor scroll through the options and click/highlight the degauss option

2) Change the VGA lead going from the monitor to the PC

3) Ensure you have no unshielded mangnetic sources near by like speakers etc

If after trying the above the fault is still apparent then unfortunatley your monitor is at fault and will need to be repaired

On screen controls have a mind of their own


The buttons are stuck - If the screen is out of warranty then i would take it apart and see if he buttons can be unplugged or cleaned up.

If in warranty Samsung is excellent with repair service. - Depending on the model LCD its either 1 or 3 years warranty.
