Light spot on the laptop screen. Dead Matrix?

Question

laptops

In general, after a 5-minute trip of a laptop in a bag to the university, I was surprised to find a light spot of an irregular shape on the laptop screen in the corner. (its edges are visible even if the laptop is turned off) I
scored, because it was possible to work. After some time, a little more than half of the screen turned into a light strip. Then the line disappeared. After a while, it gradually reappeared. Etc.
Dead Matrix? And can this be fixed at home? If not, is it not easier to buy a new laptop?

Answer 1

Dead or not, it's hard to say. Understand, look.
And you can change the matrix at home. Chinese will cost from $100 (depending on the laptop model and matrix type).

Answer 2

Most likely, something got on the diverging lens between the backlight and the matrix (water?). Replacing the matrix should solve the problem. Show a photo of the spot with the laptop turned on, without it you can only guess about the problem.

Answer 3

There was a similar garbage, but with smoother edges, I took it apart, dried it - only the replacement helped

Answer 4

I suspect that you, like me, put pressure on the matrix rather well. Here she is.
There was a post somewhere about freezing LCD displays. Look.

Answer 5

Light bar, you have problems with the inverter. Such a chip is small between the hardware of the laptop and the matrix. Looks like the cables are damaged. Disassemble, delicately remember the connection. MAY be corrected.

Answer 6

a light spot on the bottom left can mean peeling / peeling off of the polarizing film, there are a lot of tips for solving it on the internet
