Question about LG Flatron L1750S 17" LCD Monitor

Analog Power Saving Mode

When I turn my computer on the monitor stays off. I press the monitor's power button and the orange light above it goes off, obviously turning it off. I press it again and the light turns blue, the words "Analog Power Saving Mode" coming up on the screen. A few seconds after, the screen goes black and the light turns orange again. All of the solutions I've read so far have dealed with using items on the desktop, something I'm afraid I don't have the luxury of doing.

    I've had the same thing happen to me. After moving the computer & monitor, I got the same message. I've cleaned the inside of the computer out, and replaced both the graphics card AND the monitor itself; I still get the same message.

    The things you find out after you've spent the money...

    We recently bought this monitor and it was working fine - for about a week. Then it started doing exactly as everyone else has described - going into Analog Power Saving Mode. At first I was able to restart the computer and it would resolve itself (temporarily) but now I can't even get the monitor to come on, so I have no capability of resolving the problem the way some of the solutions are described.

    I'm having the same problem as well with my 19" LCD monitor (LG, Flatron). I tried every solution possible but of to no avail. So I'm wondering if it requires a graphic card. Does it? Please help.

    same problem

  • linke Jul 09, 2008

    I have the same problem as OP except it says 'Power Saving Mode' and doesn't say analog. I have tried my tower with two other monitors and it was fine so it's definitely this monitor creating the problem. I can't work it out! Also - the problem has gotten progressively worse - it used to work again with a restart, or a disconnection on the cable and rechecking - but now it doesn't work at all. Please help with ideas!

    I am also facing the same problem, i.e when i am starting the PC monitor shows Analog power saving mode & after that monitor screen goes black & LED lights orange. Kindly suggest.

    Same problem, I thought it was the drivers, but guess what, they were not on the CD rom supplied, and are not available on the LG website. But after reading this thread I guess it's an LG problem.

Firstly check the connecting cable from the screen to the computer at both ends. Ensure that the thumbscrews that keep the connector in place are tight. Has the PC been moved recently? Any chance the cable could have been put in the wrong place? You can get the installation manual on the following link to see where that cables should go: http://us.lge.com/filedown.do?filepath=1000000757&fileName=L1750B-BF.pdf Try resetting the monitor by pressing the "Auto/SET" button on the front panel for a few seconds with the PC on. If that fails you can do a full factory reset on the monitor by using the on screen menu and navigation to the "reset" function on the setings (gearwheel) page. This is described in the manual page A12. If all this fails then disconnect the cable to the monitor, the monitor should display "no input signal" if it does suspect the PC graphics card is faulty.

I had that same problem... remove the case of the computer and make sure the graphics card is in tight, and while you're at it, make sure its clean... that solved it for me.

LG does not show the 1750 monitor on their web site. It did show some discontinued monitors including a 1752, but there was no information available about them.

Another LG site said to use the far right bottom to auto adjust....for another monitor.

My HP has four buttons, MENU, <, >, and Return (also AUTO). Menu opens the monitor dialog box, with the arrow bottoms shifting through the menu. Select an item with return, then arrow to your selection, menu is also your exit button.

You may have a power saving selection here.

Also check the control panel for the POWER OPTIONS properties. A power scheme selection here will also change the mode of your monitor.

good luck

My LG flatiron W1943TB turns on, says analog power saving mode, goes black and then the power button flashes.. but the monitor is hooked up to my dell notebook bc my LCD died

Hi erin mckinle,
That is probably it's, uh, analog power saving mode. When the screen goes black and the power button flashes, make some mouse gestures or hit some keys that would not affect anything (try spacebar). That should bring up the screen. If you think it goes into power saving mode too fast, go to Control Panel --> Power Options, and change the values. Hope this helps.

Analog power saving mode?...

I have a LG flatron wide keeps saying Analog power saving mode and than powers off how do I reset this?

New LG 2452T keeps going to digital power saving mode

i had the same problem.
connect the monitor with the analog cable and shut down your pc.
while it is off unplag the analog cable and place the digital one(dvi).
this should fix your problem m8 ;)

"analog power save mode"

different monitors have different settings. Anyhow, press the menu button on your monitor (hope it is there otherwise some other button must have been assigned this function). Choose recall or auto adjust or factory default from there (whichever of these options you can see). Nothing serious.....

Try connecting the LG monitor to the VGA port on the HP tablet instead on the docking station.
