Having problems with your HP Compaq nc6400 (GJ982US) PC Notebook ?

Laptop screen fades out - have to move it constantly to get mouse to work - red and blue vertical lines also appear when I'm able to view the screen


Answers :

Sounds like either a bad inverter or bad screen. The best thing to do is try to hook up an external monitor to the VGA cable and press the Fn+F7 or f8 button. Not sure which one it is on that model laptop but it should have a small computer icon or say crt/lcd on the F7 button. Also you have to be logged into do this. If it works that way you will know that it is for sure either the inverter or screen. One of them will have to be replaced.
There is either a loose video cable connection inside, or a bad video cable.
you might consider buying an external monitor and using it like that, as opposed to getting it fixed. it may cost more to have it fixed than a new external monitor.
