We also have a 2009 LG monitor and it appears to have a short of some kind. At first the screen suddenly went black and when we turned to PC off and back on we we see a brief display of the startup process, and then blank again. Any suggestions?

ac-dc inverter board ... order it through mcm electronics... open up the monitor and find the board that looks like it when you receive it, and simply swap it out.

Too think to work very well. The internet has several documented cases whereby the stand shears off and the whole thing falls to the floor. That happened to me. Luckily it was still within one week of warranty and I got LG to spring for a new one. The new one is not much better. However, I found a solution. Go to Aaron Brothers or any frame shop and get a metal 11 X 17 frame for about $10. Put the monitor on the frame stand and it works great. The actual monitor is really nice. Great color reproduction for photo editing, etc, but the stand sucks. Good luck!

it might be on the power save mode to save energy. I had that problem on my sons 32" LG we have. The energy star uses less power but is not as bright...not worth the sacrifice.

I have the same problem as you. I checked the connections many times. The display is fine and also can't recognize that i am touching the screen. How can you solved the problem?

Cannot help you, if still under return timeframe, return it. I have two units, one used for three years, one still new in box, even un-opened--was going to sell it so did not want to open the box, but decided to keep it since now discontinued. Your post reminds me--I should take it out of the box and check it. Question--are you sure it is the monitor and not your video card in the computer, or interference from some other device? Check online for like symptoms. Love this monitor. If you can find a fix, and otherwise in good condition, worth fixing yourself.

I had to find the box in the garage! On the box it shows two ways to plug into a PC (computer): a D-SUB or DVI-D then there is a headphone/earphone jack and a HDMI jack for AV equipment. I'm still using the monitor even though it developed skinny little lines across the screen. I'm up to six lines now. It's upsetting that I didn't realize it was still under warranty when the first three lines appeared. I read that LG doesn't do the ends of their pixel rows like some other manufacturers and it could cause this problem but I'm no expert.

Every time I'd turn the screen on it would be perfect, then after about 5 seconds the entire screen would become a dead pixel. The PCB going bad is apparently a common issue with these monitors. I told the seller about the issue and they paid to have it shipped back to them, no hassle. Got another one and it's perfect, no dead pixels.

Yes I messed up and bent a pin in one of the connectors, so it wasn't the hardware for me, it was my own clumsiness. So you might want to take a look at the pins in your connectors. I read elsewhere that someone wasn't getting enough power to the camera and monitor and that's what caused the blue screen for them.

I also, get a blank screen? I was going to send it back, but I wasn't sure if it was something I wasn't doing

The issue will be power, it uses two powered USB ports for power supply. The port on the monitor is a micro USB you could probably use alternate means of power. I don't have the power specs on hand to advise what would be best for alternative power.

I can confirm problems with DVI cables received with 2 of these monitors. Luckily, I had ordered some longer DVI Dual Link cables which got me up and running. The worst part of receiving the insufficient cables was that Windows sensed the monitors max resolution, but only produced a black screen (making it appear there was an issue with the video card).

Hard to say from the information you have. Is there any way you can use a different monitor to see if it also shows the symptoms? Or if your goal is to keep the old monitor, is there a different source device you can try?

You have to make sure that you plug the included USB cord from the back of the monitor (right next to the DVI input) into your computer (or a connected hub), just as you would any other USB hub. They certainly should have included this in the instructions!

I have mine for about a little under a year and have had no issues with it...until today - I noticed that I do in fact have a dead pixel. I will be sending this product back and this will be my 3rd monitor from them.

I had the same problem using Win 7-64. I returned it. I purchased another one, it worked for 5 days then stopped. I returned it. Not worth the price seeing you have to keep paying to ship it back. Try another brand. Now I'm waiting to upgrade to Win 8 until I can afford a better monitor because you really need a touchscreen with windows 8.

Software is needed on Windows systems. I forgot to install the software before plugging in monitor, and it would not work. It automatically found some sort of driver, but that didn't work, so I had to uninstall that driver and install from the CD, and then it worked well.
