Reason for black screen of industrial control computer

Industrial control computers are common control systems for commercial display devices, mainly used to promote advertisements, company brands, social information, and provide services for unmanned equipment operation in society. The stability and display effect of their screens are crucial. During use, black screens often occur, which can affect the normal playback of advertisements, the normal release of information, and the replacement of government front-end and back-end information.

What caused the problem? Is it usually analyzed from three convenient perspectives?

Firstly, power supply issues may be one of the reasons. Generally, devices are running for a long time. If the power supply uses components with insufficient power, it will accelerate the aging of the power supply, resulting in insufficient power supply and causing the screen to turn black.

Secondly, using low-quality memory modules and devices that are used for long periods of time, especially in self-service vending machines, outdoor charging cabinets, and outdoor charging stations, are all devices that work for long periods of time. If the memory module particles operate at high frequency for a long time, it will accelerate the aging of the particles. Causing the display to go black.

Thirdly, in addition to some hardware related reasons, internal factors such as system failures, problems with the device's operating system or playback software, can also cause black screens, such as system file corruption, unsupported content formats, and improper resolution settings, which can all lead to black screens in advertising machines.

If a black screen appears, you need to first check for hardware related issues. If there are no problems found during the inspection, it is likely that it is a software issue. If the above checks did not detect any problems, you can contact technical personnel.
