Laptop screens are very fragile the screens can be easily cracked or smashed, the screens internal cables can be problematic making the screen flash lines across the picture, screen backlights are another common problem this is where the screen is dim and you can see a faint ghosting of the picture. Cracks are normally caused by accident, or sometimes when the lid is shut and there is an object on the keyboard. Screens that are cracked can’t be repaired, we carry over 20 different screens in stock this enables us to offer a same day repair service.
If the screen is showing no picture or random characters this can be caused by the motherboard graphics chipset some HP machines are well known with this problem ( dv6000 and dv9000 ) .
A very dark screen that you can see a faint outline of the picture sometimes can be caused by a faulty screen, but is more likely to be caused by either the high voltage inverter or the screen cable that runs through the screen hinge these two components stop the back light from illuminating.
Screen replacement isn’t a “do it yourself” job the screens are very fragile and if you put pressure in the wrong place during installation and it will crack.
We can replace the screen or repair one of the other faults described above, this kind of work we do day in day out.
