20 Most Recent Samsung SyncMaster 712N 17" Flat Panel LCD Monitor Questions & Answers


More than likely, you have set the resolution too high for the monitors capabilities. Set the computer to a lower resolution, and try again. If using windows, try to boot in safe mode to accomplish this. Other OS's can take variables at boot also to do the same. You'll have to search for yours.

Good luck.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

i had the same problem.i called up the service senter of samsung and they were like, press the menu button and hold it for some time.immediately press the auto button.this would do auto lock.i mean auto adjustment lock.that solved the problem somewhat in my monitor.its not a permanent solution but it can help...

The monitor should be replaced, by your description there is more than one issue, it has a screen display problem and several buttons are not responding to any commands, and the monitor is six years old. The cost to repair would not be justified, and a new replacement would be cheaper.

Your video card and computer memory may not be sufficient to run in the recommended "optimum performance mode" that Samsung and Windows both suggest. Please try setting your display setting at a lower resolution such as 1080 x 760 which is still quite excellent. Otherwise you may need to buy a better video card or increase system memory to run the higher mode graphics.
Good Luck!

It sounds like the backlights circuits are no longer working properly.
Most failure is due to bad caps as shown in my SAMSUNG albums, you may want to check that out first.
