1. power issueThe voltage of the power supply is too low, resulting in the inability to drive the motherboard and causing a display failure of 6.

2. system boardThis is a rather complex issue because there are many components on the motherboard, and there may be many possible problems. For example, capacitors on the motherboard may lose their effectiveness due to aging, causing the motherboard to malfunction. In addition, the circuits on the motherboard may also be damaged due to various reasons, such as electrostatic discharge, liquid infiltration, etc.

3. LCD screen issueLCD screen is an important component of touch screen. If there is a problem with the LCD screen, it can also cause the touch screen to go black. For example, the backlight of the LCD screen may not light up properly due to aging, or there may be problems with the circuit of the LCD screen itself9.

4. Touch screen controller issueThe touch screen controller is responsible for receiving touch information from the touch point detection device, converting it into touch point coordinates, and then sending it to the CPU. If there is a problem with the touch screen controller, it may cause the touch screen to malfunction, resulting in a black screen phenomenon.
