    QAM Tuner Problems

    Hello Everyone,
    I am in desperate need of some advice. Since I received my new
    Panasonic plasma TV (TH-50PX60U) in early January, I was enjoying
    local HD channels via clear QAM. I am a basic cable subscriber (Wide
    Open West / WOW) and was picking up a number of digital stations just
    by scanning the digital spectrum with my internal tuner. Everything
    was fine until 3/1/07, when suddenly all of my HD channels stopped
    coming in. I rescanned the channels numerous times, and although I
    was still receiving *some* digital stations, I no longer received the
    local HD channels. I even did a hard reset with Panasonic on the
    phone, but the rescan did not pick up the HD channels.

    Here's the strange part. I picked up an external HD tuner at Circuit
    City the other day for another LCD TV that does not have an internal
    tuner. Just for fun, I hooked it up to my Panasonic and scanned all
    the channels. Sure enough, it picked up the HD channels again.

    Does anyone think that it could be a problem with the internal QAM
    tuner? Again, I am picking up digital stations, just not the HD
    ones. Also, I found some forums where a couple other WOW customers in
    central Ohio experienced the same problem as me. One person suggested
    that the channels were now being mapped to sub-channels of channels
    zero, but that doesn't make any sense to me. The external HD tuner
    scans the same range of channels (1-135), and it is picking up the HD
    channels just fine.

    Any help with this very frustrating issue would be very much
    appreciated!

    Curious, on the channels that come in, do the translations still work? I
    had a similar thing happen with Comcast Cable early this year. A scan of the
    QAM channels gets me about 30 channels, but they all translate to channel 0;
    that is, I get 30 channel 0s. I have a Sharp LCD set, and everything worked
    from September 05 until this year. There are 3 types of QAM cable. When
    doing setup, two of these work the same, the third does not work at all.

    What worked for me when I still had analog cable was to punch in RF channel
    75.1, and step through all the channels up to 99.8. This picked up channels
    that were not originally in memory. In fact, it got me some scrambled
    channels ( SciFi and Fox News, for instance).

    I have a DVR; so, not having the TV work through the QAM input is not a
    big deal, but having it work would be nice. It does seem that the cable
    companies are changing things again.

    Apparently your cable company is no longer allowing the local hd
    channels to come through unscrambled. That is not the same as the
    external hd tuner you bought. That gets the stations over the air,
    by the atsc tuner, not the qam tuner that cable uses for local hd.

    How would this be? The ATSC tuner would require an external antenna
    to be connected, right? I don't have an antenna connected to the
    external tuner, just the cable. Also, there are other WOW subscribers
    who are receiving clear QAM HD channels just fine.

    What external tuner did you get, make and model?
    If it has no qam tuner, and it likely doesn't,
    the cable itself may be acting as an antenna,
    thereby getting your stations that way.

    As far as others getting the missing channels,
    you said you have basic cable, not digital. That
    means that IF you get any additional channels by
    qam and not their box, they are not responsible
    for the ones that you are not getting. Where I am,
    I don't get one of the locals in hd via qam, even
    though others do. Should I call the cable company
    and complain, "hey, I'm not getting something that
    I'm not paying for?" Of course not.

    I have the same problem. I called Comcast and they said that they 'should
    come in.' I was thinking that it was a scheme to get us to pay for these
    channes since they know that al new HDTV's have built-in tuners.

    Chip,
    The issue, as I understand it, is that the cable company is required
    to offer the local broadcast stations and cannot scramble them by
    law. Even so, my question is more geared to figuring out what went
    wrong so that I can fix it. With an internal QAM tuner, you
    absolutely can pick up unencrypted digital channels, even if you do
    not subscribe to digital cable. There's nothing wrong with that and
    the cable companies are well aware of this, although they don't
    promote it.

    I just want to figure out what the problem could possibly be. Heck,
    as soon as I figure it out, I'll be ready to switch to an antenna
    anyway. I don't think the HD channels you get through cable look as
    good as OTA reception, so I'm probably going to make that switch. But
    my technical, curious nature led me to post here to see if anyone knew
    anything about this particular issue.

    Can you give the model number of the hd tuner you bought?

    Sure, it's a Samsung DTB-H260F:

    It does have a qam tuner, so I'll bet your signals levels are
    low causing the qam tuner in your television to miss some
    channels even though the stb picks them up. You may want
    to have the cable company check the lines for you.

    If I interpret what i read in the owner's manual correctly:
    "ANT / CABLE IN
    Connect the AIR antenna or CATV antenna here.
    Connect the cable in the event that a local cable
    provider is passing through 8-level Vestigial Sideband
    (8VSB) and Quadrature Amplitude Modulation (QAM)
    on their systems.

    Your cable provider is probably passing 8VSB for the local channels.

    That's not entirely true. The cable company is required to deliver your local
    channels in the clear. However, it is not required to provide multiple feeds of
    your local channels in the clear. So, for example, if your local cable company
    already provides the SD version of the NBC affiliate in the clear, they are not
    required to also provide the HD version of the same NBC broadcast in the clear.

    Nonetheless, nearly every cable company does provide all local HD feeds in the
    clear - even though they are not technically required to do so.

    My guess is that there is some arcane difference between config of the receiver
    and the config of the cable broadcast. Suppose your QAM tuner checks only for
    subchannels numbered 10 or less, while your cable company (for some unknown
    reason) has numbered the subchannels starting at, say, 30.

    The result would be that most tuners would work with that system (though yours
    wouldn't) and your tuner would work with most other systems (though not this
    one). In other words, it's a bug that would hinder only a small subset of users
    and would therefore be easily overlooked by the manufacturer.

    I'm not suggesting necessarily that the subchannel is the problem, just that the
    problem is one of this nature. There are many other configuration parameters
    that might affect the reception of a QAM broadcast.

    Have you tried posting your problem on the AVSforum.com?
    (http://www.avsforum.com/avs-vb/)

    There are a lot of smart people there, and one of them may be familiar with your
    tuner, cable co, or both.

    8vsb is for ota signals, qam is for cable.

    Yes, but when a cable company passes along analog channels, as most of
    them do, there's nothing to prevent them from passing 8-VSB analog
    feeds. That's consistent with the statement in the manual and with the
    OP's observation.

    That would be me. I just did a re-scan on my JVC AV-30W776 and the local
    HD channels and subs are on channel 0. I can receive them all with the
    exception of WSYX(ABC). Additional channels "in the clear" are at 112-1
    thru 112-13. None are labeled.

    Like you, this started in early March, when the locals were 201, 202,
    203, etc. and were labeled ABC-HD, CBS-HD, etc.
