My Lg Monitor that i have fails to show anything on the screen even when it is dissconected from my computer, the logo dosn't show, nothing happens when turn it off by the plug it just comes back on with nothing to show and the power button flashing. Is there anyway to fix this?
The monitor is probably on protection.
To start unplug monitor
from power and from computer and test computer with different monitor
to find out if it is monitor or computer fault.
If it is computer fault and no video signal , then test:
If it is monitor fault , then the monitor is on protection.
When on protection you keep having a flashing
led on front of the monitor , and monitor turning off by itself after a while,
that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1The
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
protection circuit.
2 The protection circuit detected a wrong
voltage or a broken contact, identified an internal fault and kicked in
, starting the flashing light.
If
you are in situation one, then the monitor will reset just unplugging
power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common
faults
that can occur are a blown capacitor on power board, faulty inverter
board, faulty input board, or a fault on LCD Digital Controller board.
Check also
the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you
can get same flashing state because of the video cable.
Try moving the video cable, and if the cable is not built in, then also try a replacement cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

My LG Flatron screen is stuck in "Power Saving Mode", any fixes Ive seen need to be done on desktop properties, but I obviousley cannot access anything as my screen is not coming on.
Well thats seems tricky does it not come on at all when you boot the computer. If the screen is working then it should work to display the Start up screen. If it does then keep pressing Delete until the BIOS comes up- then search the pages for power saving and slect to OFF

How do I Open / disassemble LG Flatron
Remove all the screws from the screen that you can, check for screws under all soft objects and labels, after all screws are removed, use a flat screwdriver or a case opener tool to start snapping the display cover open, it is hold in place with plastic clips, these will clip open but be carefull not to break any.

How do I change the language from chineese to english on a LG L1719 Sq moniter
After you have the menu displayed, go to Setup (which is the bottommost tab on the vertical panel to the left, represented by a toothed wheel) highlight the first line at the top using auto/set button, and change it using + or - until you find english displayed

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.
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.

My brother bought a used LG Flatron monitor and while cleaning it (the previous owner was a smoker), he thinks he pushed a button because he got a box with "osd locked" and "osd unlocked" that flashes continuously on the screen. He does not have internet service so I am trying to find out how to get rid of the flashing box. It flashes even when he is playing games or using other programs.
Can you help?
Thanks, Nona
Below is service manual for this. Hope it helps!

My flatron lg w2234s monitor has no picture. Blue light comes on and blinks slowly but no picture
Hi My screen developed exactly the same problem. It appears to be a hardwear problem associated with the screen it's self. continuity test is ok on the lead so I took it back to the shop under warranty and hey presto, the replacement works. I don't know what the problem is but there are a number of other folks on another thread with the same problem and their entries are dated May 09 too. Dave

My LG monitor stopped working today, there's no power. Tried a different lead so I am assumming the power supply has blown. Is this an easy problem to fix + cost effective. Where can I source a new unit power? I'm in the UK.
Thanks
Paul
It can be as simple $5 worth of caps in the power supply.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed LG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.
