Analysis: If the host indicator is on or off, the screen is not powered on (the power indicator is off), or it is powered on but there is noise, or "Noise" is displayed, the former indicates that the power supply is out of order or the connection is poor, while the latter generally indicates that the memory card is in poor contact or the graphics card is damaged. Suggestion: 1. If the monitor is powered on, but there is no signal, turn off the power supply, open the chassis, plug in the memory module again, wipe the golden finger in one direction with an eraser (thumb and nail scraping is also acceptable), and then turn it on after installation. 2. If the above operation fails, turn off the power supply and open the chassis, plug and unplug the graphics card again, and plug the data cable between the monitor and the graphics card tightly. If it still doesn't work, consider that the graphics card is damaged and replace it with a new one. 3. If the monitor is not powered on (the indicator light is off), look at the back of the monitor, plug in the power cord connected to the monitor, and check whether the other end of the power cord is powered on the socket. 4. If the host can display when it is connected to other monitors, or the local monitor cannot display when it is connected to other normal hosts, the monitor is damaged and needs maintenance.
