Hi @Vossy,
A warm welcome here in the Roku Community!
We understand you're having a problem with the channels on your Roku TV since they will not play. We're happy to assist you further. Did we recently make any changes to your network or network provider? Are your other devices able to connect to the network without any issues or latency? Do you have cellular data, so we can try connecting your device to your hotspot?
With detailed information, we will be able to assist you further.
Regards,
John
