Hi @Gungus
Welcome to the Roku Community!
Thanks for bringing to our attention that your PS5 was not detected by your Hisense Roku TV and for the steps you took to resolve the issue.
In this case, we recommend performing a system reboot on your Roku TV from the Settings menu by navigating to Settings > System > Power (Skip Power if there is no option) and proceeding to System Restart.
Please keep us posted if there are any differences after doing so.
All the best,
Chel
