Started going black, no sound a few days ago. Only happens on all Live TV antenna channels and repeats every 30 minutes on the dot, ie. 12:00 out, reset, 12:30, out, and so on all day. To get the channel back, I have to click to the next or previous channel, then click back to the one that went black. Then it repeats the blackout in 30 minutes.
Black screen lasts until you reset the channel.
Doesn't seem to happen on any streaming app.
Please, give us a fix.
