P1S (upgrade kit) camera malfunctioning

Printer works fine. It prints.

Camera stream does not appear in Studio: “Printer camera is malfunctioning”.

Remote access to Timelapse and Model on SD card does not.

Local access via control panel to Timelapse and Model do work.

Steps taken:

  • Format card in printer
  • Exchange card from other printer
  • downgraded and upgraded firmware (1.10.00.00)
  • reset to factory settings

This machine is going up for sale so I want it in top condition. Any help would be much appreciated.
