I have a hp laptop and whilst watching a video the screen went blank. I knock it and it came on but half of the screen now has a transparent film across it with colorful lines running across does anyone have any idea how to get this off my screen your assistance would be greatly appreciated.
I know a few HP laptops have cabling that runs too close to the hinge, so when the machine and opened and closed repeatedly - the cable comes loose and causes video / display issues.
If you can remove the cover around the screen and hinge area and test the laptop and get no problems then look carefully at routing the offending leads a little better. I managed to resolve a similar issue with a HP, and used a hot glue gun to secure the cables.
