How to connect analog RF cable to TV with HDTV tuner

Hi all,

I just bought the following TV - Panasonic PT-60LCX63 and need some
help....

http/catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?displayTab=F&storeId=11251&catalogId=11005&itemId=64594&catGroupId=11254&modelNo=PT-60LCX63&surfModel=PT-60LCX63&ignoreRedirect=1

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...

Maybe someone is kind enough to look at the manual and tell me what to
do.
The manual can be found here:

Any help is appreciated !
Thank you very much,
Dan.

Sounds like your TV is 'on' input B. Can you manually select any
channels on input A? Select input A, then channel search.

There probably is no difference between A and B other than maybe PIP
not supported on B.

Your TV's tuner gets OTA digital. You need a digital cable box to get
digital cable, plus an HD box to get HD.

Oops spoke to soon. Check to see if this tuner is compatible with
your cable system.
