How to fix noise on laptop screen?

Question

laptops

Once I was disassembling a laptop (Lenovo G500 which has an integrated video card) and broke something. As a result, the front cover is not held back in the area where the monitor is attached to the main body. After a while, I began to observe how the screen sometimes flickers a little or the brightness increases greatly (also flickering). It is rare to find a picture where it seems that the PPC matrix, all sorts of stripes. Move a little and it disappears. So, I'm sure that the matter is in the cable, which, as it were, transmits the picture to the matrix itself. In the area where the screen is attached to this main part, it is either damaged or simply pressed. Is it possible to replace only this stub without buying extra parts? What do you generally recommend? Yes, along the way you will have to change part of the body.
UPD: The same situation with the webcam, it does not work and sometimes the LED may flash

Answer 1

The cable from the display to the matrix is ​​removable and can be replaced.
Once upon a time, I went the hard way and soldered a worn place. After soldering, the cable lasted another five years.
