Vertical bar on the monitor. The issue is the loop. Easy to fix?

Question

Electronics

Six months ago, flooded the laptop. Fortunately, before that, the keyboard of the laptop broke, and I just bought a small bluetooth keyboard to put on top of the laptop and write. So she saved the laptop, taking the brunt of it. They took it to the sc (not very high quality, as it turned out later) where it (the laptop) was dried and cleaned. However, a vertical bar appeared on the screen. Judging by the appearance of this band, the matter is in the cable (and as far as I remember, even a drop did not hit the monitor)
Actually, what is the question: Is there an option to simply wipe the cable with an eraser / cotton swab with alcohol? Or is it still better to look for a normal cable and replace it?
I'm attaching a photo just in case.

Answer 1

When the interface from the motherboard towards the matrix (what everyone here feels is called a "loop") is broken, color music begins or "it goes out, then it goes out." It's more like peeling off the controller-matrix contacts, where special adhesive tape is most often, partially conductive, glued with a hot stamp. But on some matrices, this place cannot be reached without destruction, in which case the matrix goes to trash. If I'm right, then 3500 is the normal price for repairs

Answer 2

This is a problem with the matrix, there is an assumption that you have replaced it with a defective one.

Answer 3

No, this matrix is ​​dead.
