Thanks for posting, and welcome to the Roku Community, @MPK63!
We appreciate you for letting us know about the issue you encountered when streaming your TCL Roku TV after an update. No worries! We're here to help you get back on streaming.
To troubleshoot the problem to help you stream without interruptions, try doing the following steps:
- Navigate to the channel tile on the Roku home screen, press the * key on your remote, and choose 'Remove channel.'
- Next, restart your device from Settings>System>Power>System restart (If you do not see a Power submenu, skip to the next step).
- After your Roku device restarts, visit the Roku Channel Store and add the channel again.
In addition, try reinserting the cables at the back of the TV and make sure that it is properly seated.
Please let us know how it works, and we'll continue assisting you from there.
All the best,
Chel
