If the LCD screen flicks on and off and you can see a dim image on the screen when you view at a sharp angle, then most likely you have a faulty inverter or a faulty CCFL lamp.

Check the video card first, if you have another vidoe card try it. If that does not shore up the problem the monitor would be a issue, and now a day monitors are dirt cheap even for the LCD monitors so I would look into buying on of those if your inclined to do so.
There is a focus adjustment inside on a part called the flyback transformer. It's located toward the back of the circuit board, and you'll know which part it is by the red cable going from it to a connection on the picture tube. The flyback generally has two small adjustment knobs on it. The focus knob is the upper one. Slightly turning this one way or the other may improve the focus a bit, but usually a sudden loss of focus means either the flyback or the picture tube has failed. Either of these is cause to treat yourself to a new monitor. You can buy 17-inch flat screens now for less than $150 at regular prices, and sometimes you'll catch a good sale at the office stores.
If you choose to try the focus adjustment, BE VERY CAREFUL!!
1) You have to remove the back of the monitor and work with the power on. Parts inside, especially the picture tube, can give you a very nasty shock AND EVEN KILL YOU.
2) Be very careful where you are putting your fingers when working on a live set. Make sure you have a safe grip on the adjustment knob first, THEN look at the screen while you adjust it. Don't go blindly reaching around.
mt, the 6 to 8 lines you were seeing were most likley the prelude to the end of the monitor. If the problem only occurs when the screen saver comes on then I could say the driver maybe being corrupted by a certain screensaver picture or program. When the monitor warms up to a certain temprature the electronics start to fail. You may want to turn off the monitor while your not right in front of it to cool it down and prolong its use.
