I have a Roku TV model 40R2A5R, software version 14.5, hardware ID H804X. When I watch OTA live channels, as a new program begins, the screen goes black. The TV remains on, and I can scroll to another channel, tune it in, then go back to the preferred channel that blacked out, and select it and it will come on, until the next program, then it happens all over again. Does not happen on streaming apps or over the internet stations. Seems to happen on all OTA channels. Waiting for the black screen to change doesn't seem to work, it stays black. I have to divert to another channel, then back to the one I wanted.
