The Troubleshooting of White Screens for POS Billing Machines

June 21, 2024

POS billing machine white screen means that the screen is completely white after the POS billing machine is turned on, without any content or icons. The fault not only disrupts normal payment operations but also causes inconvenience to daily business activities. POS billing machine white screen may be caused by a variety of reasons. Below Sunany will introduce several common reasons and troubleshooting methods:

Software Conflicts: The software on the POS billing machine may conflict with other software or drivers, resulting in a white screen. Upgrading or reinstalling the software can resolve the issue. However, ensure that you back up important data before updating to avoid data loss.

Display Problems: The display itself may be faulty, such as backlight issues or loose/damaged display interfaces, causing a white screen. Connect a different display (like a monitor or TV) to the POS billing machine to see if the problem persists. To Determine whether the issue lies with the display or the POS billing machine.

Data Cable Connection Problems: Unstable, damaged, or loose data cable connections can lead to data transmission errors, resulting in a white screen. Check and replace the data cable, ensuring that all cables are firmly connected to the POS billing machine. Tighten any loose connections and inspect for any signs of damage.

Power Supply Problems: There may be problems with the power supply of the POS billing machine, such as unstable voltage, and loose or damaged power cords, which can cause a white screen. Ensure that the power supply is stable and the power cord is securely connected to the POS billing machine. Try using different power sockets or power cords to rule out power-related issues.

Hardware Failures: The hardware components of the POS billing machine, such as the graphics card or motherboard, may be faulty, resulting in a white screen. In this case, the faulty hardware component may need to be repaired or replaced. If necessary, contact the Sunany technical support team for further assistance. We will be happy to guide you through additional troubleshooting steps or arrange repairs if needed.
