Self-explanatory, laptop screen only shows black and white lines or rainbow lines. I've tried connecting it to an external monitor through HDMI-VGA and the screen there is perfectly okay. What could be the problem here?
Can you run this test if you need an external monitor? I tried the test and it displayed various colors until it got stuck on the black/white lines again
