It can be bad lamp assemblies if all the voltages and everything else checked out good.
Learn more here on how to find out if lamps are bad (not 100% since you do not have the lamp tester or inverter tester).

Try these steps for resetting.

1. Unplug power cord from wall and monitor, if it unplugs from monitor.
2. Unplug the video cord from monitor and computer both.
   
3. Hold all buttons on the monitor down for about 10 to 15 seconds while everything is unplugged.
4. Plug everything back in and see if that fixes it.

I know it sounds weird but holding the buttons down releases any residual juice ( power ) in the monitor. If this doesn't solve the problem you may have a bad monitor cable. I would see if replacing it helps.

Hope this was helpful.
Good Luck

It may mean that your computer is in sleep mode.

change power supply output section capacitors.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, 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 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.

Try it on another PC first.

oke having a similar problem atm, this is what i have found so far. was trying to help a friend who has bought the same 19" LG monitor. When i connected the monitor to her PC i noticed that it was not the same connection as the previous one but it had the smaller blue connection..this shouldnt be a problem but it was. The monitor when powered up, showed LG logo then went into power saving mode. My next step was to try the monitor on my own PC to make sure it was working, When i did this the monitor got a signal but on the initial boot it did say that this monitor was not compatible currently the way i had it set up ( where i had it plugged in? the only place it can be) because of my graphics card. oke so atleast i knew the monitor was working and was recieving a signal.

the only difference i can see is when i put it in her PC it is not giving me this information which also did give 3 steps to solving the problem but didnt seem legit. the next step i will take is to try my monitor on her PC although im not sure i expect it to work.

i think it must be a) PC is now faulty or b) PC is not sending a signal to the monitor ( possibly due to the fact it is not the same connection as before.)

what i have seen on other similar posts says you should also listen for your PC starting up normally.

another thing i would like to know i think it can be usefull for this topic. are the people who are experiencing this problem in the same situation as me i.e. changing the type of connection used by the monitor from the larger to the smaller type?

id also liek to note that the monitor i have was bought on a tight budget from PC world.

only other help i can give to people with this problem is that it is much easier to see where the fault is when you have 2 PC's and 2 monitors i know this is not viable for many but if atall possible interchanging parts with the PC that is working correctly and the one black screening can help you see exactly what the problem is,

as far as i know aswell the main reason for a monitor to sleep is that its simply not getting a signal from the PC BUT on rare occasions it can be a fault in the monitor. IF you have another monitor with the same connection that you can get yto work on the same PC its the monitor with the problem, if u have a monitor that u know is working on another PC with the same connection but is not working on the PC in questions its a PC fault.

sorry for the jumble of words in this answer i tryed my best to explain, all my knowledge of PCs is from friends and self tought so ... hope it helped

Rotated or upsude down displays are caused by unintentional pressing Ctrl-Alt plus the down arrow key.
Restore by pressing Ctrl-Alt plus the up arrow key.
ALSO
To change the display from portrait to landscape
Press Ctrl-Alt plus a left or right arrow key.

Some computers do not have this function.

You are more likely to have bad caps in the power supply, open it up and look for bad caps, worst case will be bad lamps. See example here: http://s807.photobucket.com/home/budm/allalbums

Hello,

This usually indicates a blown power supply. Heat buildup in the monitor case causes parts called capacitors to overheat and blow out. Check out our web site at: www.ccl-la.com/badcaps.htm We have pictures of wha the blown capacitors look like. Open the back of your monitor and look for the blown caps. Replace all the ones that look like the ones in the pictures and you should be back up and running. The values you need to get are going to be marked on the sides of the ones you take out. Be sure to reinstall the new ones with the polarity stripe going the same direction as the old ones come out. You can order replacement parts from several places on the internet or we can supply them for you. You will need to use high temp caps that will be marked 105c, these are not available from Radio Shack. If you use ones that are not rated correctly then you will have more issues in a month or two. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping.

I hope this helps, If so please rate our solution.

Usually hitting a button on the keyboard or moving the mouse works.

If it is really a problem go into your display settings through the control panel, access the power options and stop your monitor from going into powersave mode.

go back into the menu and start hunting and toggle all the settings untill toy can see something you recognize to get it back
Special reset button to reset it to MAnufacture's default or is that also encripted
