I stepped on my sony vaio laptop screen and the screen got vertical bars (looks like http://www.thecomputercellar.com/wp-content/uploads/2013/01/jxGIxm.jpg).

I ordered a replacement and installed it. Looks ok, boots fine, but the bars show up as soon as Windows starts loading. I figure I must have damaged it during install.

I ordered a second replacement, same thing happens.

The video driver seems ok, because an external monitor works great.

Is this a hardware/connector issue? If so, can I fix it?
Is it a software/driver issue?

Details: sony vaio model number VPCSE13FX/S http://esupport.sony.com/US/p/model-home.pl?mdl=VPCSE13FXS&LOC=3&session_id=5f5c2efeb7732bd114c574a433aeedbc#/howtoTab

Solution
This issue is usually related to the graphics card and not the display but since the external monitor works properly, I'm going with a damaged cable from the motherboard to the display - That's what I'd look to replace here.
