Vertical lines on my old macbook (2008)

Hello, My macbook Aluminum unibody 2008 has strange vertical lines that seems to disappear when i move screen or touch black spot (I don't know the name of that part it showed in the picture ).After awhile the first line don't disappear even i move the screen, after that the second line appeared they are the same size.When i record screen with screenflow or take screenshots the lines aren't visible.I will buy new mac but i need to fix this one first...I need a name of the part that i need to replace.
Here some pictures:



Thanks,

Either the flex cable is bad (the part that goes between the LCD and the system board) or the cable is loosely seated (or both). Either way, I'd pop off the bottom panel and have a look.

That cable is referenced here:

I'd start by re-seating it. If that doesn't work, I'd inspect the cable all the way from the system board to the back of the LCD to make sure all is well.

iFixIt has instructions for the entire process.

Thanks a lot i thought that something similar is happened.
It helped the cable was bad so i am going change it with this one
