What if the laptop screen doesn't light up?

The reason for this problem is many, one is the screen contact is bad, the second is the problem of the high pressure board, the third is the screen has a problem, the other is still a lot of possibilities but most of the above, especially the screen line contact with poor and high pressure board problems. The problem can be solved either in a situation where considerable operational capacity and spare parts are required.

As for the solution, if the warranty must be found after the sale, but if the warranty period you will be able to open the screen to remove screen, to remove the screen is not your problem, if the solution is better, if not solve the big situation is high pressure plate, I am afraid you can not solve it, In that case, you can only find a repair point. But remind: must find a slightly regular point!

However, the following reference points are used to understand learning:

General notebook screen flashing because of the screen data cable is not good, loose caused, if the screen of my book before and after shaking, there will be screen flashing. If there is a problem with the screen of the notebook, usually do not appear occasionally flashing phenomenon, only in bad contact with the situation can occur.

There are two ways to fix this:

1. Pry the plastic shell on the keyboard of the computer (my computer can, I do not know if you are able to), the line to drag, so that can be a few weeks.

On the screen after the keyboard is open, the location of different notebooks is not the same.

2. Can not be handed over to after-sales service processing. It takes 100-200 dollars to get a new line! This will solve the problem of screen flicker forever.

The screen is the only signal path between the notebook motherboard and the LCD high Voltage board. From a technical point of view, the normal boot, the motherboard to the LCD High-voltage plate issued a light signal, when the LCD High-voltage received this signal, will open the LCD lamp power supply, if not the signal, you can not light the LCD lamp. If it appears to have a bad contact or a line breaker, will cause the motherboard issued by the LCD screen light signal can not be conveyed to the LCD High-voltage board, which led to LCD High-voltage plate can not normally open to the LCD lamp power supply, and led to other hardware in the notebook to start normal, but the screen does not show the failure to appear.

Notebook Screen Cable

From the above picture we can see that the screen itself is very fragile, and it is in the most frequent notebook activity of the screen axis position, and frequent bending notebook LCD screen is the main cause of the damage screen line! Therefore, the author reminded the Notebook users, In use should minimize the bending of the laptop LCD screen frequency, at the same time, in the bending process of the force should be even, so as to effectively extend the life of the notebook screen line.
