- The cause of the screen cable error can also lead to the situation of the LCD screen being jerky. The screen cable, whether laptop or desktop, after a period of use can be worn out, the contact pins are poor or damaged due to impact. If on the computer we just need to remove the cable and replace the new cable, on the laptop you have to take it to the store to check and fix this common error on the LCD screen.

The port could be oxidized, and the internal Chip could also be due to usage errors, overheating, or improper cleaning.

There are several reasons why the screen automatically turns off without a specific time while in use, and the main reason is a screen error. Because the screen has been used for a long time , some internal components may not operate properly and may be faulty.
