Question about Samsung Syncmaster 192N 19" LCD Monitor

Samsung SyncMaster 192N loses picture; requires re-boot

I have had this monitor for maybe 3 years -- NEVER a problem. Normally it goes black upon "hibernation"(?) when left on for awhile, but the green light is still on and a swish of the mouse brings the display back quickly and beautifully. All of a sudden yesterday the display *NO LONGER* comes back from hibernation -- I have to hard-REBOOT it, blind, whereupon the display comes back just fine and asks me for my password, etc. and it works -- until I leave it for a small length of time and it goes BLACK again, and the green light is on, but my mouse can't engage it. [Otherwise, the mouse is just fine...] I am very concerned that I could have something important on the screen, get distracted, and then really screw things up as I would be flying blind and yet maybe... Perhaps I caused this by unintentionally changing a setting somewhere? I'm definitely NOT a techie... any words of wisdom for me? Thanks, Chris

Unfortunately, you two have two unrelated problems. CB, the monitor isn't asking you for the password, that's the computer itself going into hibernation, which shuts down the video output, hard drive, etc. You need to go into the power-save settings and either disable hibernate, or change the settings to your liking.

The other question about the screen staying on for 5 seconds... thats an inverter board problem.

    I'm experiencing the same problem as cb-nickname, where the screen on my SyncMaster 192n goes black, and the only way to turn it back on is by hard re-booting my computer; sometimes even ctrl-alt-del doesn't work, and I have to turn off the power strip several times. It didn't used to act this way; a simple mouse-swipe used to re-activate it.

    When the screen does come back on, it usually works fine, so it's not the same problem as the second poster. I decided to run an experiment, and hooked up a different computer tower with a different OS to the monitor, and the same thing happens after several hours. To be sure it's something with the SyncMaster and not my computers, I dragged up my old CRT monitor, and both computers and old CRT monitor operate perfectly well.

    I don't understand why I should now have to disable hibernate on my computer in order to resolve the problem, when I didn't have to do it there any way to do a power-save setting, or am I just going to have to power-down every time I step away from the computer for a couple of hours?

I posted my "comment" and detailed explanation of the problem above, and afterwards, went back to see exactly what my power-save settings were....Hibernate was NOT enabled in the first place. Any other ideas of what the explanation might be, given that the Syncmaster monitor didn't behave this way when it was new?

I have the same problem with my Syncmaster 192N. I can hit the power button on the monitor and the picture comes back for about 5 seconds...then black screen. It just won't stay on. Hopefully someone knows the answer.

Seen a spate of these issues of late, I'd think its caused by failing Power capacitors, either bulging or blowing or leaking. You need to get this checked by a technician or TV repairman

My guess is your video card driver has been altered and is causing the problem. Try rolling back the driver before reinstalling the monitor. Here is a link to the manual for your monitor:

From the above manual: "The PowerSaver system operates with a VESA DPMS compliant video card installed in your computer. Use a software utility installed on your computer to set up this feature".

I believe the power led button is still on while the screen goes black, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes black after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes black.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Follow the instruction below to solve your problem:
Restart your computer and enter Safe Mode (press F8 right as the computer starts booting up. Choose Safe Mode in the menu, press Enter twice).

While in Safe Mode, open Control Panel and go to Add/Remove Programs (Programs and Features on Vista/7) and uninstall the display driver software/drivers.

Restart your computer and boot normally. Now you should be able to see everything. Things might look bigger and uglier, that because there's no display driver installed. All you have to do now is reinstall the display driver. Use it's original disc or go to the manufacturer website and download the latest driver.

Good luck!

Call and get the RMA for your monitor, the problem is in the power supply and it will only get worse. This is a common problem with LCD monitors after 2-3 years of use.

My three year old Samsung SyncMaster 192n keeps turning off. If I unplug the power supply and plug it back in it will turn on for a while. Any suggestions?

You need to replace either the caps or the inverter board. You may require an assistance from a repair person in replacing it. Check this link so that you could see how the inverter board looks like:

Have a good one!
