1. Check whether the power supply of the host is working normally. First, check whether the host system is powered by checking whether the power indicator on the host chassis panel is on and whether the power supply fan is rotating. Secondly, use a multimeter to check whether the external voltage meets the requirements, too high or too low voltage may cause the automatic shutdown protection of the host power supply overvoltage or undervoltage circuit. In addition, it is important to check the quality of the power switch and reset button and whether they are properly connected to the motherboard, because the power switch and reset button on many inferior cases are often damaged after several uses, resulting in a black screen of the whole machine. If the power supply is damaged, replacing the power supply can solve the problem.
2. Check whether the LCD screen power supply is connected. When the LCD screen is powered on, there is a "click" sound, and the power indicator of the LCD screen is on, and the user moves to the LCD screen screen with a "sizzling" sound, and the sweat hair on the back of the hand stands up.
3. Check whether the signal line of the industrial LCD screen is in good contact with the display card. If there is a lot of dirt on the interface, broken needles and other damages will lead to poor contact and a black screen on the display. 4. Check whether the graphics card is in good contact with the motherboard. If the LCD screen is black and the speaker in the host emits a long and two short beep sounds, the industrial LCD screen indicates that there is a problem with the connection between the graphics card and the motherboard, or there is a problem with the connection between the graphics card and the display screen.
