Re: SyncMaster 712N monitor problem

I've had a similar problem. I took apart the monitor (it was out of warranty by that time anyway) and found the lamps would not stay on. They'd flash for a split second before remaining unlit. I tried hooking up another LCD monitor's lamp to the Samsung, and even though I knew the other lamps worked fine, they exhibited the same behavior. Looks like something's wrong with the circuitry. The LCD actually does display the desktop on screen correctly. It's just the lamps refusing to stay on.

Re: SyncMaster 712N monitor problem

Start by checking all the connections. Boot to safe mode and see if the problem persists. Check your power saving parameters and see if the monitor turnoff is set too fast. This could be a hardware problem also, especially the monitor or the graphics card.

AOC 917sw starts normally then goes black after a few seconds?

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.

Monitor cycles on and off. There is a display, but only shows for 1/10th of a second. Its a image flash, then black screen, wait for one minute, then it tries to turn on again.

Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied 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 goes wrong:
Post back what you see inside so we can guide you further.

I have a Samsung 712n monitor that passes a self

jcriley, If your SAMSUNG is not to old, try to get them to replace it or do a cash+old unit for a same model refurbished unit! You may have a monitor that has a "switch-mode-power-supply" that is in partial or full shutdown mode. When very strange and weird things start to occur with a LCD fluorescent lamp backlit monitor or for that matter LCD tv/monitor I would always suspect the culprit to be the SMPS!!! Get back to me lmistyrel@ aim or 12fixlouie on fixya after you perform SMPS evaluation test using the flashlight trick to see if the screen data is still being displayed even though the screen appears to be blank. It may only be BLACK, but not blank!! Read some of my other posts here on fixya and also visit a website FYI !! It is run by another tech on fixya nickname "buddymc". If you do a second post, give us a little history of unit in question such as age and screen appearance just prior to BLACK SCREENof DEATH setting in! 12fixlouie

Monitor goes black

Kindly attach the screen to your another system or note pc. Else being a simple device it contains only three main parts.
1) Panel
2) Power supply + HVPS
3) Main board
need to be tested one by one.

When I power up my PC and monitor, the screen comes on for a couple of seconds, then it goes black

this happens with a few monitors and some graphics cards. if you connect your monitor through a DVI cable, try connecting it through an analog cable. if possible change your graphics card, that should solve it completely.

Please try to connect your monitor to another PC, if still the problem exist, then probably an internal electronic part/s is cold soldered / defective, which I suggest to bring the unit to an authorized service center to fix the problem. regards
