I got a HP laptop. Offlate,my screen has been flickering a lot...to the extent that i cant even see a thing. If i give the screen a small jerk i.e move the lid up and down, the flickering stops for a while and starts again. The flickering has got so severe now that the screen does not stay stable for more than a couple of minutes. Is it just a loose wiring problem? Could i solve this at home with a proper set of screwdrivers? If not, could you please let me know what kinda problem this is, and how do i work it out?
