Many sets will not tune or display a channel without performing a channel scan... to create the table data that is used to control the tuner.
Some of my sets will accept manual entry of the real channel number.

Do you know how if I can find out if my Samsung UN55B7000 might allow direct tuning without a scan? I've looked around, but that's not mentioned in the manual.
I'm suspicious that I may miss out on weak signals that does not appear at the precise time I scan.
That might explain why last night I could not get channel 8-1, which I can get today, while the situation is reversed for channel 5-1. Manual tuning might allow me to add entries to the table without removing existing entries.
@David Loudin: You and GUM are an amazing source of fascinating information that 90% of the population wouldn't need or care about - just the kind of stuff I like!
If you have more, keep it coming.
