The TV has the following tuners:
- NTSC tuner (Standard analog broadcasts)
- ATSC/QAM tuner (SDTV and HDTV broadcasts)
I just have analog cable at home (TVMAX).
At the back of the TV, there are two antenna RF inputs (A and B).
Input A is labeled 'Cable In'.
The instructions say to always connect the cable to A. Only if you
have both (antenna and cable, use A and B).
BUT:
When I connect the RF cable to A, the channel search doesn't find
anything.
When I connect the RF cable to B, all channels are found.
The instruction doesn't say so, but is it possible that input A is
just for digital cable and doesn't accept an analog connection ?
Or should a digital connection be downward compatible with an analog
connection ?
I really don't know what to do. I called the Panasonic support and
they told me there 'MIGHT' be a problem, but they don't know exactly.
I should ask a local dealer. But they also didn't know....
I would like to know if input jack A is broken or really only can be
used for a digital connection.
I normally wouldn't mind to us B, but I just need to know what's
wrong...

Check page 27 of the manual. I think your just scanning the B input. You
can hook up to A, but if you don't scan it, you'll get nothing, since your
really scanning B all the time. Try it

Not likely, also per page 27. I think both antenna inputs feed an
all-channel analog tuner, but you can only do QAM on antenna (A). This is a
guess and since you don't have digital cable, there's no way to test the
theory. At any rate, see page 10 of the manual and see the buttons marked
Item 20. You should be able to toggle between the two antenna inputs. If,
when you select A you lose signals since you're connected to B, you should
be able to go behind the set, move the input connection to A and have your
signals back. Try it.
Tell me approximately where you live and I'll tell you whether you have any
over-the-air ATSC service nearby. It'll be interesting to see if you can
receive ATSC on either or both antenna inputs.
