Lenovo mobile phone gold fighter S8, 4G, boot black screen, how to phone 20

Reasons and solutions for the black screen of your phone:

1. The black screen of the mobile phone may be a problem with the connection line between the mobile phone screen and the motherboard, it may be that the contact is a little bad after falling, and sometimes it can be recovered, but if there is a slightly more violent shaking or a long time with the screen (such as looking at **) causes the contact line to overheat, it may be bad contact, so it is a little unstable. If it is detected that there is indeed a problem with the contact line, it is recommended that you repay the mobile phone directly, because it is generally more expensive to replace the mobile phone screen, manual costs and material costs, and it is not as good as the original after repair, and it is easier to break, so it is better to directly replace it with a new mobile phone.
