The black screen of the POS cash register is also a relatively common phenomenon. There are many reasons for the failure, such as Trojan horses, motherboards, graphics cards, and CPUs that can cause the black screen of the cash register. If we encounter a black screen at the cash register, we must start with the display to determine whether the black screen is caused by insufficient external power supply, and whether the power supply is powered on.
After checking that it is not an external problem, start with the software. If the black screen is caused by the Trojan horse, if the cash register is unfortunately hit by the black screen Trojan, there are two ways to fix it.
1. By editing the registry, restore the Shell value of Winlogon to Explorer.exe;
2. Or use security software to repair system failures while thoroughly cleaning up the “black screen” Trojan.
Finally, there is the hardware. If the black screen is caused by the hardware, what we can do is to check whether there is a heat dissipation problem, and use a small fan to blow the cash register first. If not, turn off the cash register and try to pull out the memory stick. , clean it up and then plug it back in. If the screen is still black after booting, then we can only send it back to the silver machine manufacturer for repair. It needs a professional technician to test and judge to determine which aspect is causing the black screen.
1. Check whether the data cable of the display is broken or deformed;
2. Check whether the power cable and data cable of the monitor are connected properly, and then change the monitor to another computer to test to see if it can display normally;
3. If the computer has an intermittent black screen during work, this is affected by the voltage instability, and it will return to normal when the voltage is stable;
4. Check whether the power supply is normal, check the power supply of the chassis power interface and the power cord, check whether the interface and power cord of the main chassis power supply are loose and whether the display is turned on. If the interface and power cord are damaged and broken, they should be replaced in time, and the power fan should be confirmed Exhaust.
