Question about Samsung Syncmaster 17" 720N Monitor

1 Answer

First the monitor on Syncmaster 720 kept popping up stating that the auto adjustment was locked. NOW it keeps appearing as auto adjustment scanning in the middle of the screen. How do I get rid of it. The menu button doesn't get me to the point of following the factory reset suggestions.

AUTO ADJUSTMENT LOCKED BOX FLASHES ON THE SCREEN ALL THE TIME.


Depends of what seems to be a problem.
If you want to get rid of that message box, appearing by itself, then probably you need to take front panel PCB with buttons and replace "Auto" one, 'cause it's stuck.
If you want to unlock an Auto Adjustment and other functions in your monitor, then press and hold 'Enter' button for 5 seconds.

Use best quality data cable directly from VGA card to LCD input and your problem will be fixed.
Usually that problem oocured when we use external tv device with CPU and monitor so signals gets weak and auto adjustment popups.

Ok. as stated in chat, here is the button sequence that will reset your monitor to default. if this doesn't work, then your menu button is either jammed or broken and will continue to pop the message up. at that point it will need to be repaired of replaced.13f16c4.jpg
