Psirhilsa, there are several possible causes.

 

1) The contacts between your monitor and the diplay circuitry are probably held together by pressure (they are not connected). GENTLY grasp the edges of your monitor and twist SLIGHTLY. If the display changes, worn or dirty contacts are your problem. You might even fix the problem by cleaning the contacts this way.

2) Believe it or not, the problem can be caused by a bad RAM stick. Go into Control Panel-System and see how much RAM you have. However, if a defective RAM stick is still working, this will not solve the problem.

3) The power inverter board controls your backlight. It might be defective. If you can adjust the brightness, however, that is not the problem.

4) The cable to your monitor might be going bad.

5) Plug in an external monitor. If the problem still appears, then your laptop monitor and connecting cable are not the problem.

6) Easy cure that probably won't work: move your speakers and see if that helps.

7) Depending on your rig, see if you can get to your video card´s control panel and adjust the horizontal or vertical syncs. There might even be buttons on your monitor for those two functions.

 

 

This happened occasionally when I taught Computer Science. We just ignored it. Remember that your netbook is low-budget and probably will cost more to repair than it is worth.
