Question about Averatec 4200 Notebook
There are 3 main issues that can cause this:
First I would determine whether your GPU is at fault as this is the easiest thing to isolate. You can do this by plugging into an external monitor. If the lines are still there on an external display you can be fairly certain your GPU is faulty. In this case I would recommend getting the GPU of the laptop re-balled or replacing the mainboard completely. Unless you have a separate graphics card in the system such as MXM, then just replace that or get the GPU on that re-balled.If there is no distortion of image on an external display then you have isolated the problem to the screen panel or LCD cable of the laptop.
Secondly I would check you LCD cable is seated correctly. If not re-seat and test. Hopefully this will cure your issues. If this doesn't cure your issues, while the laptop is running try to flex/bend the LCD cable and see if you see a change in the distortions to the image displayed. If you do, you probably need to change the LCD cable.
Thirdly if you have got the stage where you have tried flexing/moving the LCD cable while the laptop is running and the action causes no change in the distortion of image it is most likely that your LCD panel has a problem and needs replacing.
Hope all this helps :)
