How to remove ripples and blinking of the screen?

Question

laptops

Yesterday everything was fine, but today, suddenly, right at the start of the computer (even on the boot screen), terrible ripples appeared on the screen and part of it twitched and jerked. Temporarily fixed it by tilting the screen (I wonder how it worked at all. If the screen is level, then this horror is coming, and if it is tilted forward or completely tilted forward ... It’s not tilted, but lies straight! That seems to pass. But it does not affect the root of the problem).
Please tell me how to fix this.

Answer 1

Congratulations, you have broken the cable connecting the display and the video card. Take your laptop to a service center.

Answer 2

The cable to the display must be replaced with a new one.

Answer 3

For starters, you need to try tilting the entire laptop. It is necessary to find out - the matter is in the tilt of the screen or in the angle between the screen and the main unit.
So - it seems that the cable from the main unit to the screen either broke or jumped out of the socket.
As an option for some cases (when you don’t have to go anywhere): attach an external monitor to your laptop.
