My LG Flatron L1511S 15 in. Flat turned into Power Saving mode when I plug in serial cable!

lower your resolution to VGA and work your way up. Note that if you choose differnt geometry, the screen edges will hang off the ends of the monitor and you can not see then.. If you are out and can not see to change, you will have to boot up in safe mode (f8) and adjust down then reboot to normal.

good luck!

LG W2353 dvi power saving mode
how to fix ?

Hook a spare monitor to the computer, if the same symptoms occur the problem is the Video Graphics Card in the computer, but if the picture is okay, it is clearly the LG Flatron that has the problem, and if possible sub the video cord from the computer to the monitor just to be sure.

Hello davidhague99 ,
Check your VGA cable if connected properly to your CPU or Video Accelerator Card,if connected properly,try another VGA cable and if the problem persist you need to try another source.
hope it helps thanks

Is the monitor connected to the computer using a VGA plug (a smaller one, with 15 pins in 3 rows), or a DVI plug (wider one, with flat pins in 2 rows)?

From what you write, your monitor is switched to the analog input (VGA). It doesn't sense any signal on that input and hence goes to power down mode.

You need to go to your monitor's on-screen menu and select the digital input - you should see the picture then.

hi,

check first if the connector has no connector pins wha are broken or shifted. if not chack cable for hard nobs or turns maybe cable is interrupted.
take other schreen to check VGA output of PC.
if all this not helps mail me back
greetings cis

You need to check the monitor cable if it is correctly connected to the motherboard port. If the analog display or no signal it means the monitor cable should bot connected. If you have a video card in your motherboard you can plug your monitor cable to the external video card.

Prevent the laptop/desktop monitor from going to power saving mode:

Click on Start | Control Panel | Power Options.

In the Power Option properties window, click on the Power Schemes Tab

Set the Turn off Monitor/ Turn off Hard Disks option when on Power (and also Battery for laptop users) to Never.

Now click on the Save as... button and assign a name to this power scheme... Let us call it 'Presentation' and then click on OK.

That's it congrats!

Most screens will show nothing or go to power saving mode until the PC is turned on. The monitors need a signal in order to be 'active'.
From your description it could just as well be a problem with the PC rather than the monitor. The easiest way to find out is to connect another PC or laptop to the screen or connect another monitor to the PC unit.

Did you try pressing the Del key or F2 key when you turn on the unit to get into the Bios?

I had the same problem with my LG Flatron (not the same model as your one). I fixed it by connecting both the digital and analogue cables from the pc. Presumably, the problem occurs because the monitor is not receiving a digital signal.
