Question about LG Computers & Internet
My 23' flatiron monitor switches to power saving mode just a few seconds after I boot up my PC. I turn on my PC, then the red blinking light (which all monitors do I expect) switches to a non-blinking state when I turn on my PC, which proves that it "recognizes the PC booting up" but then immediately switches to power saving mode. I have another smaller monitor and tested my PC using that. No problem there. So there's an issue with my monitor. My power supply did short out yesterday, and died (there were a couple sparks), so that PC is inoperative. Could this have somethign to do with it? how do I fix this?

SOURCE: Going to Sleep
Due to the power surge, it is highly possible that the monitor was given a boot by your computer on it's way out.
This will short out a very small transistor inside the monitor on the video board and in turn, then monitor cannot see that there is a signal so goes to sleep.
If you get brave enough to venture inside the screen, then check near the cable input. The transistors are only around 3mm and have 3 legs (two one side and one in the middle on the other).
If you find anything like that burnt (get a magnifying glass) then replacing the board is the easiest option. Just don't be tempted to wipe the board before you look at everything very closely, you may wipe away the tiny bit of evidence you are looking for.
Hope it helps =)

I have an LG W2261V, and an old Sharp LL-T19D1-H. The PC runs both just fine, and the PSU has plenty of power. Unfortunately the LG handles power save mode very differently, where the LG would not switch on after entering this mode unless reset (unplugged, PC rebooted, etc). Extremely frustrating, as the old Sharp never had any problems exiting its own power save mode. The LG would enter this mode based on the monitor power settings (in whatever power scheme you are using) in the screensaver tab in display properties. I fixed this by selecting "Never" for "the Turn off monitor" property. I guess this is a warning to those who may wish to buy a new LG monitor, but want to use a power scheme to turn off the monitor.

Check the capacitors on your monitors circuit board. If they have opened up at the top, they are fried. Buy new ones, make sure nothing has leaked from the old ones, and replace them.
