What to do if Siemens Touch Panel external monitor remains dark?
- SScott SimonAug 2, 2025
If the external monitor remains dark, first ensure the monitor is switched on and not in power save mode (press any key). Then, increase the screen brightness. Also, check that the power cord and monitor cable are properly connected to both the monitor and the system unit or grounded outlet. If the issue persists, contact your technical support team.
