1 Answer

I use two monitors and the NEC is beginning to flicker a little and when I just got back on the computer it wouldn't come out of sleep mode until I turned it on and off.

    Actually instead of going to sleep it goes to standby after 4 hours. The power setting is set to never turn off. This fllickering has just started after a couple of years.

    The monitor now will stay on for about a minute and then goes to black. I can turn the power off and back on and it will repeat the process each time. Stay on for about a minute or two, ,then go to black. HELP!!!

    I switched the monitor plugs on the computer and it does the same thing no matter which monitor plug I put it in.

Yes sleep mode and hibernation are not good programs to use on a computer. They cause many problems. I would recommend going to control panel, display settings, then screen save, then power options. Now just change when the monitor turns off and when and if you want your hard disks to turn off. You would be ok with just having to monitor turn off.

    Does it flicker when using either screen? If that is the case, check the card make sure it is in tight and no loose solder joints or connections. Updating the drivers wouldn't be bad idea either.

    Make sure the monitor cord is plugged in tight to the computer and that no pins are bent. Check that the monitor is on the 110 voltage setting (not all monitors have this switch)
    Check the contrast and brightness adjustment. If the monitor to computer cable detaches from the monitor, exhange it for a cable that is good. or check the cable for continuity.
    Confirm that the proper system configuration has been set up. Some older motherboards have a jumper or DIP switch you can use to select the monitor type.
    Test a monitor you know is good on the computer you suspect to be bad. If you thinkj the monitor is bad, make sure that it also fails to work on a good computer.
    Check the CMOS settings or software configuration on the computer. When using windows, bott into safe mode.
    Try reseating the video card. For a PCI card, move the card to a different expansion slot. Clean the card's edge connectors, using a rubbing alcohol and a cotton swab.
    If there are socketed chips on the video card, remove the card from the expansion slot and then use a screwdriver to press down firmly on each corner of each socketd chip on the card. Chips sometimes loosen because of thermal changes.
    You can also trade a good video card for the video card you suspect may be bad.
    Another thing you can do is go into CMOS setup and disable the shadowing of video ROM.
    You can also test the ram on the motehrboard with diagnostic software.
    For a motherboard that is usingan AGP or a PCI Express video card, try using a PCI video card in a PCI slot.

    If you have a different monitor to try and use, then you can check or change the video driver configuration.

Monitor with lines and flickering but monitor is fine

It might have been caused by an outdated video card driver. To check that, go to safe mode and observe if you experience the same issue.

To go to safe mode, do the following:

Restart your computer and tap F8 until you see safe mode. Use the arrow keys to highlight safe mode and press enter. Once you're in, observe if you experience the same problem. If you still have the problem, then it's the connection between the monitor and the motherboard which causing the problem. You need to reset the connection or get it checked by a technician.

If there are no problems inside safe mode, then update the video card driver. You can also automate the updating mechanism of your computer's drivers to make sure that you won't be getting any problem in the future. You can use RadarSync to automate the updates.

I hope this helps!

My screen symtoms are a little different on my L1975NW.

I am guessing the LED power indicator blinks green then becomes steady when the screen "turns on" (shows video). The problem is most likely a failing backlight power supply. That's why there is a 30 minute delay. Try to disable sleep mode and see whether that helps.

Compaq Presario stuck in sleep mode

Connect the monitor to some other computer, e.g., a notebook, and see if it does the same thing. If it does, then the monitor is the problem.
If it does not, then your computer is not putting-out any "video" signal, and so the monitor goes to "sleep".

If you have MORE than one VGA-output port on your computer, connect your monitor to the "other" VGA port.

Or, press-and-hold the ON/OFF button on your computer, to force it to completely shutdown.

Dim monitar with flickering screen


The problem can be caused by 1 of 2 things either your power supply is going out or the backlight bulbs are going out. The most likely cause is the power supply. If you are willing to do a little soldering you should be able to do the repair. If you go to our web site at: We have a section on monitor repair. Look under the Samsung 930B it is the same as your monitor.
If you don't want to do it yourself we do offer a repair service, email me if you are in need of that.

I hope this helps.

How do you put a monitor into power save?

Depending on your operating system go to Control Panel of Windows and find the Power Options section.
There should be a setting there to change how long to waite before the monitor sleeps.

Hmm... is still not working

Start your computer and tap the F8 key as soon as the computer begins to power-up. Keep tapping until you come to the Safe Mode screen. When the screen alerts you to the fact that you have chosen Safe Mode, click OK.

When you get to the desktop go to the control panel and launch System Properties. Go to Hardware and Device manager. Click the arrow next to the Display Adapter. Point at the adapter, right click and chooser Properties. Click the Driver Tab. Roll back the video driver to previous driver.

If indeed you have installed a new driver that is not compatible with your video card, then rolling it back to the original may very well take care of this problem.

Good luck!
