First, check all of your cable connections between your Set-Top Box or Lite Box and TV. Make sure that all connections are tight and secure.
Next, reboot the Set-Top Box or Lite Box. It may take a few minutes for your box to reboot; you'll see the Layer3 TV profile login screen on your TV after it has finished rebooting.
If rebooting the box does not resolve the purple dots issue, try resetting your home network:
1. Check if you have a Layer3 TV MoCA device. The MoCA device is a small plastic box, branded with the Layer3 TV logo, connected to your router or cable modem.
2. Unplug your cable modem, router, MoCA device (if applicable), Set-Top Box, and Lite Box(es).
3. Plug in and restart all of your devices in this sequence:
- MoCA device (if applicable)
- Set-Top Box
- Lite Box(es)
