F16v4 WiFi no longer showing on the display

Went on vacation and when I came back the WiFi IP address no longer is shown on the display.

The LED displays do go bad on occasion and replacements can be ordered on Falcon's site. https://pixelcontroller.com/store/main/66-oled.html

If the display is working and you are just missing the IP, I would reset the controller to factory settings, update the firmware to Build 34 and see if that resolves.
