I have a Sharp dumb TV, model LC-32LB150U. I'm looking at cutting the cord,
and need to figure out what local channels I can get. With an indoor
antenna, I've found that the antenna pointing direction makes a big
difference in which channels show up on auto-scan, so I'm unable to get all
the potentially receivable channels in the channel list at one time. The
TV's menu offers no option to add channels manually. I can delete channels,
but not add them.

So I wondered if there's a service mode or menu, and if so, how do I get to
it, and is it likely to allow me to add channels manually?

If that doesn't work, can anyone suggest how to solve this problem? I was
thinking an antenna rotator would solve the actual reception problem, but
all the channels have to be in the auto-detect list somehow. I would rather
avoid two antennas, although that might work temporarily to get the list
right.

I'm not aware of any TV that will allow you to add OTA digital channels manually; they must be scanned for. Some better sorted TVs will give you the option of rescanning and *keeping* the previously scanned channels. This allows you to scan, rotate the antenna, rescan, rotate again etc. until you get all the available channels in your area. Most TVs however dump the memory every time you scan.
