Laptop screen flickering and horizontal lines problem in Inspiron 15r SE 7520
I've a Dell inspiron 15r se laptop which is 1.1 years old( model - 7520). It was working fine until last couple of days. Last week it started giving a horizontal white dot line on the very top of screen( like this ............. in white) for the entire width of the screen.It appears every 2 or 3 sec. And screen will jump a bit (like say 5 pixel or so roughly) and it will also shake sometimes which makes letters difficult to read.
The problem exists everywhere,even in boot screen. In short when I press power button and screen start displaying something problem also starts.
Today I connected an external lcd monitor via vga cable and it works fine. No line and no flickering. So I guess GPU is ok?? What could be the problem?? Could it be just loose contact or something in laptop screen cable?
Another question: I had warranty including accidental damage protection and stuff for a year. But since I'm outside this period now, what should I do?
And since I'm outside the warranty period anyway is it okay if I open my laptop and try something?
Please Help!!

Hi, it could be either the screen or the screen cable. I had a similar problem whereby the screen would flicker to white. It was the screen cable causing the problem as it is routed underneath the hinge which connects the screen/lid to the keyboard. When you open your laptop the movement causes the hinge to rub against the cable eventually it will tear through the cable.
I would recommend you take it to someone who knows what they are doing to check it out and confirm what is causing the problem. I managed to find a replacement Dell cable on eBay for £10. If it is the screen don't worry they are quite straight forward to have replaced.
Hope you manage to get it sorted out.

I went to Dell service center some days back. They are presuming the same. But the problem is intermittent. Also my laptop is getting overheated since few days.
My Dell experience is haunting me.
Anyways, thanks for the reply.
