I have a TCL Roku TV, 49S405, purchased in late 2019, attached to a Roku Streambar, purchased in late 2020. It's been working fine, until recently. Now, sometimes when I turn the TV on (using the TV remote, not the Streambar remote, because I use live TV via antenna), no picture or home screen appears, though the lights appear to show both devices are operating. The only way to get the picture going again is to unplug and replug in the TV and Streambar. This doesn't happen every time, but often enough to be annoying. Is there any way to fix this?
