There can be two.

Does the power indicator of the monitor turn on when the power is turned on? - If it does not light up, check the power cord plug and socket. on, check the cable between the monitor and the main unit.

All of the above is normal, is it hot to touch the tail of the shell with your hands? hot, check whether the graphics card in the host is loose, unplug it and plug it back in. It is not hot, the monitor is faulty and needs to be sent for repair.

It's possible that the graphics card is broken! It's also possible that the monitor is broken! Or maybe the graphics card is too dirty! Unplug it and wipe it to see if it can be!

1. Sometimes the laptop is turned on, but the display does not light up, which is generally due to the failure of the motherboard self-test or the problem of the screen lamp.

2. First of all, we must determine whether it is a real black screen or a pseudo black screen, the pseudo black screen is that the screen backlight is gone, and you can see the words on the screen if you look closely.

3. If it is a pseudo-black screen, it is generally that the lamp is broken and the lamp needs to be replaced. It is recommended to go to a professional repair shop for repair, if it is still under warranty, then it does not need to be cost.

4. If it's a really black screen, it's basically a broken graphics card or South Bridge. You can connect an external monitor to see,It's connected to the VGA port of the notebook,If the external monitor is also like this,It's basically a problem with the graphics card。 If the external monitor is normal, then it is the problem of the screen itself or the screen cable.

There is a 20% chance of a problem with the screen itself or a screen cable, and an 80% chance of a graphics card failure. Because the external output and the laptop screen output are two independent output modules. If the graphics card is broken, a replacement graphics card is generally fine.

It may be that the screen cable is in poor contact or damaged, and you can try to plug and unplug the cable again.
