My new 65” UHD U7900F 4K just started dropping local antenna channel 4 broadcast after becoming glitchy. All of the other local channels work, and the problem channel for this TV works well on an older Samsung TV. To restore the channel I have to do an auto tune, and it does the same thing almost immediately after being restored. I’ve checked for software updates, and done all of the other troubleshooting. I’m not sure what’s next. tv is less than a month old.
