As long as I don't link the Roku to my network and let it update, it is functional as a TV.
But when I link it, it will update and then not be able to get past channel 2. The other channels are blank.
BUT if I turn off Bandwidth Saver, then it seems to work fine. Looks like a software issue.
Roku TV D301X
Onn model 100012590
Software version 11.0.0 build 4193-D8
Or, if I reset the device to OEM without linking it, TV channels work.
