A black screen is the most common problem when using a computer in daily life. So what is going on in this situation? Today I have brought you a detailed introduction to the problem of black screen on computer display. Let’s take a look at it together.

Why the computer display screen is black:

1: The power supply is insufficient.

1. Monitors that are too old or consume high power will not be able to start normally.

2. The external power supply voltage is unstable, too high or too low, which will cause the monitor to go black.

2: The switch circuit is damaged.

1. A fault in the monitor switch circuit is the main problem causing a black screen.

2. A short circuit in the power supply or damage to peripheral circuit components can also cause this problem.

3: The outgoing circuit is damaged.

1. Failure of the horizontal output circuit or picture tube and power supply circuit will also cause a black screen problem.

2. This problem is more likely to occur, especially if the high-voltage package of inferior monitors is damaged.
