How to fix blank display on Fortinet FortiFone FON-C71?
- DdavidfranklinAug 9, 2025
If the display of your Fortinet Telephone is blank, confirm the phone’s power source. If you're using the power adapter, ensure it's plugged in; if it still doesn’t work, replace the adapter. If you're using Power over Ethernet (PoE), ensure your Ethernet cable is plugged into the INTERNET port on the back of your phone and that the PoE switch is properly configured. If it still doesn’t work, replace the Ethernet cable.
