Toshiba LCD TV Model 22C1004, made in Nov 2010.

This has been a great TV, with lots of extra features that other
small TV's don't have. All of a sudden, channel 2.1 and 2.2 are
not coming in. The signal strength indicator does not even
register. All other channels are fine.

First thing I did was to unplug it, reset it and the scan all the
channels. All channels came back except 2.1 and 2.2.

I have a rooftop antenna with the lead going to a splitter and
then to this TV and another one. Next thing I did was to swap
the cable connections at each TV. Same problem with Toshiba.
Other TV picked up 2.1 and 2.2. So the connections and cables are
eliminated as problems

By swap do you mean you swapped the tv sets around? If that's what you
did, did the known working tv pickup the missing channels on the cable
wire the non working properly tv was just connected to?

If it did, you likely have an issue with the tuner itself inside the
tv. This might possibly actually be a known firmware issue and a fix
might be available for it. You may want to check with Toshiba's website
concerning your particular model TV concerning that.
