I have 2020 Q70T. I use an OTA antenna to get my local TV stations. I recently rescanned my channels and lost one my local stations (three digital channels). Even when I use my remote to manually tune to the station, the TV says weak or no signal and will not got to the station. Super frustrating since the other FIVE TVs in the house get the stations to include a very old Samsung tv and a very new Samsung Frame. When I check the e-manual it says to go to Broadcasting>manual tuning, but I only have an Autotune function. Any suggestions?
That's likely a limitation of the antenna you are using and/or its (and the TV's) location relative to a window or wall. If you are using and OTA antenna, you need to be able to place it where there would be no interference - someplace directly in line with a window. Closer to a window the better, even if you have to purchase an extension cable. You cannot manually add a channel the antenna won't pick up.
