    Monitor Blanking (XP)

    My Dell monitor (a large LCD, 'UltraSharp") has started going blank (blacked out) after several minutes. Moving the mouse or hitting the keyboard won't 'wake it u' It used to be fine but started doing this a few days ago. Any ideas what might be causing something like this?
    Or what I could look for in the Task Mgr.?

    I already turned off the power saving feature, so the monitor never sleeps now, but it still happens.

    Thanks!

    Re: Monitor Blanking (XP)

    Can you bring it back at all?
    Reboot or anything?
    How old is the monitor and video card?
    I would be more suspicious of a hardware failure than a settings issue.
    Heat build up. Fan failed or clogged.
    Video card failure
    Monitor failure.
    In that order.

    It is an LCD monitor - heat & age (3 yrs?) should not be an issue. I had the problem you refer to with CRT montiros before and this does not act like it.

    I have to cycle power to the monitor to bring it back.

    Should not does not mean it COULD not be an issue. Electronics can fail anytime, new or old.

    Re: Monitor Blanking (XP)

    This is gonna sound silly, but FIRST check the power and video cables at the back of the monitor. If one of 'em gets the tiniest bit "loose" or even wiggled a little bit, that could cause a problem. I don't think it's the case if you're able to re-power the thing, but can't hurt to check... (the location and angle of those connectors can be awkward)

    Sorry to say, it looks like your monitor is dying. Do you have any other monitor to check your computer settings?

    I saw 5 years old LCD monitor that goes black after "Windows is starting" splash screen.

    Thanks - I checked the cables first thing.

    It makes no sense to diagnose a problem by replacing a $1,000+ piece of hardware.

    Does anyone have any ideas to troubleshoot software bugs or conflicts???

    </center>He wasn't saying you should "replace" the monitor. He was asking if you had another working monitor in the house or that you might borrow from a neighbor or friend to see if it is in fact the monitor or something inside the PC. It's best to test the hardware first and this is the most reliable way to test the monitor.

    Sure, we have lots of them BUT the indications are that you have a HARDWARE problem, not a software or settings problem.

    I do not have another monitor to try.

    I am surprised that people like viking would withhold potentially helpful information, when there is only an "indication" that there is a hardware problem.

    Re: Monitor Blanking (XP)

    Variations on a theme of Energy Star Compliant might be considered, not because the monitor is kaput but because whatever turns monitors off when it figures they've been on too long is kaput. It's like having your thermostat go bad when there's nothing wrong with your furnace.

    That's an optomist's view. I'll get back to you later when I'm a pessimist.

    Oops. I just discovered that you said you turned off the power saver settings. Which settings? Windows? Dell's? The monitor's own? If you have or borrow another monitor, try setting it back the way it was and see what happens.

    "People like viking" are not withholding information from you.
    It seems like you only want to hear what you want to hear. Everyone answering your post has <big>indicated</big> a hardware problem but you only want software solutions. Sorry.

    Re: Monitor Blanking (XP)

    We may be working at this from the wrong end. Why not try plugging your monitor into another computer?

    A laptop would be most convenient because it is portable, it would be advisable to have one that is not risk-averse, it will have to have the appropriate driver installed or be plug-and-play, and it would settle the matter in two minutes flat. (Or half an hour if it takes as long to boot as mine does.)

    Hardware, software, with no mention of human error.

    Let's try screen saver. You may have inadvertently set your screen saver to BLANK, and the time to the exact length of time you have told us it takes before it blanks out. What are your screen-saver settings? Admittedly, you should be able to bring it back to life with the mouse or keyboard, unless, of course, you or someone else with access to the computer has password-protected that screen-saver, in which case you are in deep trouble with any monitor and whoever knows the password is not. Check and see if it's the same length of time every time, and let us know how long it is. You're the one who is witholding information -- we don't even know your computer specs.

    Is there a CD in the drive? If your boot sequence looks there first and it isn't a boot CD but is something that might mess up the works, that may be something you overlooked.

    You have said that the screen blanks and that you have no response to either keyboard or mouse, but are there any signs of life, especially the light for the hard drive, or even the sound of the fan running? While you're at it, follow Big Al's advice, but this time for the keyboard and mouse and be sure they're securely plugged in. Did they work before the screen blanked, or wasn't there enough time to find out?

    Are you on a network, including a home network? If so, can you see this computer from a different machine, or still better use the keyboard and mouse of this machine to display operations on the other monitor. This takes us back to the question of what computer you are using to post to this board. If you have a second computer in the same location, all you have to do is plug the offending monitor into it to test it, as I have already pointed out.

    No, you did not state that power management, standby, suspend, hibernate, sleep, power save are all turned off, and you do not appear to have looked them up. Power management, for example, is not something you turn on or off -- it's an entire set of options in Control Panel with a virtually infinite set of possible settings -- open Control Panel and see for yourself. The Energy Star thing I mentioned is typically part of a device itself, and I don't think you have any control over it: -- a monitor simply shuts itself off or powers down after a certain period. I'm not sure about that myself -- that's why I told you to read the manual or look up the specifications.

    I hope you will review those suggestions, and inform us graciously of your findings. If and when you solve the problem, I suggest you post the resolution so that others who may have a similar problem will be able to learn from your experience.

    Edited by HansV to correct link. The syntax is <!t><!/t>www.somesite.com<!t><!/t> or <!t><!/t>description<!t><!/t>.

    If you have access to a computer, and you must have or you wouldn't be reading this, then I suggest that you do your homework by reading any printed documentation you have, and google or otherwise review power management, standby, suspend, hibernate, sleep, power save as well as anything else those items might lead you to.

    You might find this link

    useful.

    Be prepared to report your findings. This will be on the Final.
