What you need:
From the information you have provided us, it seems likely that you require a replacement laptop screen cable, rather than a whole new replacement screen.

Please note that we do not take responsibility for the diagnostics made with this troubleshooting tool, if you are unsure please seek professional advice.
Isolate the problem:
If the laptop has been involved in some kind of impact, (such as being dropped), or any other kind of shock, it is a sensible idea to ensure the problem is related only to the LCD screen itself.
Connect an external monitor to your laptop and test the machines keyboard, hard disk drive and CD/DVD drives. If all looks and sounds okay it is more than likely that the problem is related only to the laptop screen itself.
