    If your HoloLens 2 is showing three lights flashing and the screen is not displaying anything, it may indicate that the device is in an error state. Here are some steps you can take to troubleshoot the issue:

    1. Charge the Device: Ensure that your HoloLens 2 is charged. If the battery is critically low, it may not start correctly.
    2. Perform a Hard Restart: If charging does not resolve the issue, try performing a hard restart:
      • Unplug the Type-C cable to disconnect the device from the power supply.
      • Hold down the volume down and power buttons for 15 seconds. The device should automatically restart.
    3. Check LED Indicators: If the device still does not start, observe the LED indicators. If the LEDs light up when you press the power button but there is still no display, this may require further troubleshooting or recovery steps.
    4. Recovery Options: If the device remains unresponsive, you may need to follow the recovery procedures outlined in the HoloLens recovery documentation.

    If these steps do not resolve the issue, consider reaching out to Microsoft support for further assistance.
