Welcome and thank you for posting here in the Roku community, @HotDawggie.
We appreciate you reaching out and sincerely apologize for any trouble and inconvenience this may have caused. No worries! We're here to find you the best resolution possible.
Before proceeding, may we know when this issue started happening? In addition, have you tried to check your network connection's signal strength? It may be a possibility that your network is unstable thus the black screens and grayed-out icons.
We suggest trying to reboot your modem and router. If the issue still occurs, try connecting your TCl Roku TVs to an alternative network connection to see if it will make any difference. Perhaps a mobile hotspot would do.
Please let us know how it goes and we'll continue assisting you from there. We'll be anticipating your response!
Best regards,
Carly
