    LG Flatron 22" wide screen has similar problem. Sometimes the monitor comes on for awhile, then goes black. I swapped it with another monitor and determined that it is a monitor problem, not a graphics card or driver problem. Sometimes I can turn monitor power off for a few minutes. When I turn it back on I have just enough time to close any programs on the monitor before it goes black again. Now, my second LG monitor does the same thing. Except, before it goes dark, I get a "going into power save" message. Nothing will bring it out of that. 2 bad LG monitors out of 2. Doesn't say much for LG quality.

When the picture disappears again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.

Power board capacitors failing, what you are getting is the inability of the capcitors to hold the charge necessary to power the inverter to fire up the screen, means investigating and replacing the faulty ones

Unplug your monitor cable. If it still has green lines it is the monitor if not then the video card. Hope this note helped you.

Lg flatron blank screen

t certainly seems like the monitor is not getting a signal. Did this happen after you changed something, or just on normal boot up?
It could be the video card that has failed.
Also, check the pins on the connector; sometimes they can get pushed in.
If you can, try swapping out the video card or use the monitor on another computer.
Good luck,

Screen flashes only for a split-second (as a second display for an iMac)

The inverter is faulty.If your Monitor is powered by a mains'kettle' type lead,then it MAY be repairable,provided you can find someone to do it.If you have an external power supply,then the chances are you have a separate inverter,and it is doubtful whetther you can find the fault or a replacement circuit board....which is why we have become a throw away nation !!
