    I have and LG 1932tq and this same thing is happening to me. The monitor will turn on and function the first time for about 30 seconds and then the screen goes black, but the monitor power indicator continues to be lit up in blue as if it is connected and on as opposed to being amber, on but no connection, or off, power is off. If you turn the power button off and then on again it will just flicker and go off. I am thinking that it is heat related- bad sensor, burned out component??

Won't go into sleep mode


Which operating system ?


Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work.


This option cuts the power to your monitor, powers down the hard drive and pauses all functions until you awaken the computer from hibernation.


Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money!


Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow. Mouse over the arrow.


The Shut Down menu appears.

Point at "Sleep" and click on this option.

Your Windows 7 computer goes into sleep mode.


Wake your computer from sleep mode by jiggling the mouse.

There may be a delay of a few seconds before your hardware powers on.


All of your open programs are still open and your work is intact, just as you left it before the computer entered sleep mode.


Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time.


Click "Start" and select "Control Panel." Click "System and Security."

Click "Power Options."

A menu opens.


Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode.


If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity


Your Computer in sleep mode


First, save all of your work. Information in computer memory is not saved while your computer is on standby.


From the Start menu, select Settings, then Control Panel, then Power Management.


Click Standby Beside When I Push the Power Button.


Push the Power button.


Automatically Putting Your Computer on Standby


Save all work before leaving your computer.


From the Start menu, select Settings, then Control Panel.


Double-click Power Management.


Set the times that you want your system to go on standby, to shut off the monitor and to shut off the hard disks.


Click OK. Your computer will go on standby according to the schedule you have entered.


Putting Your Computer in Hibernation


From the Start menu, select Settings, then Control Panel.


Double-click Power Settings.


Click on the Advanced tab.


At the When I Push the Power Button On My Computer screen, click Hibernate.


Click the Power button.


Hope this helps.

If your computer is indeed running, simply unplug your monitor from the wall, and then plug it back in. This will bring your monitor out of power save mode instantly.

LG Flatron L177WSB-how would I use my newly purchased unit after switching it on, LG logo appears followed by the Power Saving Mode it all goes black on the screen.


Hi, the Power Saving Mode, turns the screen off to conserve energy. On the remote, press Menu, and scan to Power Saving Mode. You can change the amount of time, when the Screen turn-off, the TV shut-off etc. You can set the time to (5 min) to, (never, turn-off). This should help with your problem. Thanks paul7of9

My monitor shuts down after one second.


Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computermag-glass_10x10.gif has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.
  1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
  2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
  3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
  4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."

My gateway monitor shows a picture for about 1 second then turns to blacked out screen with power light still on. I can shut the power off on the monitor then turn it back on only to have it do the same...


Your power settings may need to be changed, it appears to be going into sleep mode or power saving mode.

If you are using Vista, Click Start> Control Panel > Power Options > "choose when to turn off display" (in the left hand pane) and check that it says at least 10 minutes. Click apply and then ok.

Alternatively, right click on your desktop, select "personalise" and click on screen saver - then select "change power settings" to bring you to the same thing.

If you have xp, right click on your desktop and select "properties" then "screensaver| > "Power" and change it to turn off the monitor after 10 minutes. Click apply then ok.

If your monitor is going to sleep, either press a key or wiggle the mouse to wake it up.

Hope that helps.

My desktop pc has gone into power save mode


Turn the whole pc off then back on. If the LCD stays in power save then I would try a diffrent monitor on the PC. If that fixes it the the monitor is probably stuck in power save. Check www.lcdrpair.us for parts and instructions.
