    Monitor goes to power save mode

    I'm having the same issue with an LG Fantasy, 19".

    Upon purchasing an Xbox 360 Elite and using the monitor as it's display with a HDMI/DVI converter and my 5.1 speakers as stereo, the monitor continued to work fine on the PC upon a cable swap - until running GTAIV. It no longer functions as a PC display, automatically shifting into standy upon reaching the desktop. The BIOS and XP loading screen -do- display.

    I can only assume that with these minimalistic LG products, beautiful as they are, some internal mode or setting is being altered by our actions, software or other hardware plugged into the monitor, and with the Fantasy for example, there is only ONE button on the body of the monitor, a touch sensitive power switch.

    These mode switches are impossible. I'll try safemode in a few moments and if that fails, I'll take the screen to a friend's house and test cables.

    My recommendation, having not yet tried more than simple, late night methods, is to plug the monitor into another computer, and if you get a display try to default the monitor's settings before plugging it back into the old computer, and trying another monitor on your old computer to reduce video settings until you isolate the issue.

    Good luck

    Have a Flatiron (W2241T) that worked fine with an old Dell desktop. We had a power outage at home and when we started up the screen went automatically to power saving mode. Need some help.

    I plugged my LG 171OS into a MAC Ibook laptop thing. screen works when connected to MAC, but as soon I plug into PC hard drive its on power save...I have read through solutions posted here, but as it just flashes "power save" then turns off, and screen is black, I am struggling to work out how to reconfigure screen blind-I can't see anything on power save. I know nothing of motherboards nor do I dare open the hard drive...surely there's a simple Control ALT delete kind of combo that will wake the damned screen up??? I am typing this on the MAC laptop without using the LG screen.

I have an LG W2261V, and an old Sharp LL-T19D1-H. The PC runs both just fine, and the PSU has plenty of power. Unfortunately the LG handles power save mode very differently, where the LG would not switch on after entering this mode unless reset (unplugged, PC rebooted, etc). Extremely frustrating, as the old Sharp never had any problems exiting its own power save mode. The LG would enter this mode based on the monitor power settings (in whatever power scheme you are using) in the screensaver tab in display properties. I fixed this by selecting "Never" for "the Turn off monitor" property. I guess this is a warning to those who may wish to buy a new LG monitor, but want to use a power scheme to turn off the monitor.

I had the same problem on LG monitor too. the problem started when I accidentally bump my computer's desk. i can not see anything on my monitor because my monitor went automatically into power saving mode and i can not fix the problem with the keyboard or mouse because i don't have any PS2 on my CPU. WHen I try to open my CPU there will be this beep sound twice. So I try to check and reinstalled the memory and the VGA card and it miraculously make my computer active again. I hope my experience will be useful to the others.

It's an LCD so the problem is most likely the back-light inverter board. Take a flashlight and shine it directly into the screen from the front. Can you see the image on the screen now? If the image is there but you can't see it without the flashlight than the inverter board needs to be replaced. This is a VERY common problem. Good Luck and let me know what happens, His Dudeness

When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

Check the display settings of your video card. This can be done by right clicking on the desktop and selecting properties. Then go to the settings button and clicking advanced. All video cards are different, but there should be a tab there that will allow you to configure how you want to monitor to be utilized (mirror of laptop screen or extenstion of laptop screen). Often times, laptops have a button to toggle between modes (Example, DEll is Fn F8).

SOURCE: Monitor automatically clicks into power saving mode

Laptops often have a function key which switches from laptop only, external monitor only, laptop & external. One of the top number keys, along with the function (fn for short) must be pressed simultaneously to step through these.

Where these keys are at, may differ from laptop to laptop.

How do i brighten my lg flatiron monitor


You should have a option for Brightness in your monitor control panel. If you dont you can do it in windows aswell via Nvidia Control Panel/ AMD Radeon Settings depending on the Graphics Card you have.

You should be able to see brightness options in them pretty quick.

I don't have video on my 400sd4 laptop


If the system is booting up completely and you can hear is starting up then the problem is limited to your video.
First try this
Boot up your system so that it's in windows (listen for start sounds and windows music etc)
once you believe the system is fully booted press and hold the FN key. While holding FN press and release the F3 key one time and then let go of FN. Wait a few second and see if the LCD screen comes on. If it does not try FN-F3 a couple more time, waiting a few second in between.
If that does not work then try plugging in and external monitor to verify that the system is working otherwise. If the external monitor does not come on right away then press Fn-F3 again with it attached to allow the system to send a signal to the external port.
If it works on the external monitor but cannot come on the LCD screen, the that indicates a problen inside your laptop or LCD screen.

Monitor TFT 5015 now says "going to sleep


Make sure the laptop's external VGA port is turned on. There will be a function key somewhere on the keyboard (location varies by manufacturer and model) that controls the connector. If the connector has gotten turned off the external monitor will go to sleep because it's not getting any input.

Acer 3100 screen wont turn on.


Have you tried hooking an external monitor to the system? If that works you may have accidently switched the screen to an outside monitor. Or you could have a bad connection. Try starting in safe mode and see if it works.

Cant open attachments


That's not a problem with Vista, rather it's most likely a problem with the web server. Make sure you entered all your web server information in correctly (pop3, SMPT, etc), and make sure your mail server supports MS Outlook 2007. Just double check everything. If that doesn't work, try completely un-installing and re-installing Outlook 2007. If all fails, try downloading a 3rd party mail application and see if that works.

Try changing to a different video resolution setting. Most monitors work well with the resolution set to 1024 X 768. I'm not sure what operating system you're using, but here's an example of how to do it with Windows XP...

Right-click on your desktop...then click Properties -- Settings --
You can try different resolution settings in the settings window.

Good luck...and I hope this helps!
