    I have an *old* Sat-B55 that has been used mostly for music as part of a home audio installation. Lately though, I've noticed it can't get certain DMX (Sonic Tap) channels. Zen (857), Dance (859) and Light Classical (866) for instance, give me nothing but "Searching for satellite signal..." messages. Most of the other music channels work however. And my HD receivers get the channels just fine.

    I've rebooted and reactivated the Sat-B55 multiple times. ;)

    Is my receiver simply too out of date tech-wise to get those channels?

    thanks!

    Some of the music channels are beamed from DirecTV's 119ºW satellite, not the main 101ºW satellite. I'm guessing your old B55 can see that satellite.

    Check on which sat/tpn the channels locating http://www.dbstalk.com/showthread.php?t=196104.
    What dish you have ? One LNBF (very old), or two (Phase II) or three (Phase III) ? Or post close picture of it.

    i was thinking it was one of the older sonys that only picked up 101 but maybe not that one does appear to be multisat but still really old just call for a service call and get it fixed its only $49 or free if you have ptotection plan

    So, we're back to the question - what dish is OP using ? How many LNBFs at least ?

    Pretty sure it's the 5 LNB Slimline.

    And my Sat-B55 can select an oval 3-sat dish in the menu.

    These channels worked a couple weeks ago I'm sure. And I've changed nothing on my end.

    According to what's on the transponder map thread, same bird, different transponder.

    0 SONIC 856 6 D9S @101W 101 00BE SonicTap: New Age xmvisns (<- I can receive)
    0 SONIC 857 22 D9S @101W 101 00AA SonicTap: Zen xmchill (<- I can't receive)

    and interestingly enough, this one:

    0 SONIC 864 22 D9S @101W 101 00BE SonicTap: Symphonic xmclsc

    which is listed to be on the same transponder as Zen, I can get. Maybe they moved things around again and the guide data hasn't been updated, since channels on 119 aren't listed on my guide.

    OK, lets check signal levels of those tpns on your Sony B55.

    91+ on 22 and 6

    the Sat-B55 only shows satellites as "A, B & C" and doesn't give any specific designation. I'm assuming A is 101 based on the numbering of the transponders.

    That's correct.
    By old DTV terminology: satA - 101W, satB - 119W, satC - 110W. If you had all three, your dish is Phase III type.

    As to initial issue, check with CSR, perhaps they change packaging of those audio channels.

    That would not cause a "searching for satellite signal" message.

    There have been changes to the guide data over the past year or two resulting in much more data being sent. As a result, older receivers such as the one in question here are no longer able to properly handle all of the data.

    I don't know the details, but I suspect the problem here is along these lines. A newer basic HD receiver (currently the D11 or D12) should solve this problem. The OP should be able to call DirecTV and have his older receiver replaced at little or no cost.

    Data overload. Don't we all suffer from that these days. ;)

    Well, I guess this was inevitable. Substituting with a D12 is easy enough, but then the issue is that I need to have all the touch panels throughout the house reprogrammed to support the new receiver (an older Elan system, where everything is decentralized). Wah. :nono2:

    Thanks!

    I wonder if you change your sat setup on your B55 to 18" round dish, which would give you only channels from 101°, if you would be able to tune in the stations you're missing now. I think the music channels from 119° are international in flavor.

    I forgot about this until today, but one of the nice things about the Sat-B55 is it shows you what sat and transponder it is trying to tune in for any particular channel. You have to work back through the menu and System/Antenna choices to get the info.

    For my test case "Zen" (857) it says it is tuning into Sat A (101w), 21 and for that it gets no signal. Nothing. According to the latest maps, that's the right place. The guide data for the channel does come up, as far as song title goes, but "Searching for satellite signal" is there. What's funny is every other transponder that it does receive on 101w is like 93+ in strength. It's like the receiver doesn't think it's allowed to talk to that transponder.

    I do actually have a tech coming out today to re-peak the dish, as my HD channels have been "brriiping" a lot lately. 103ca is ranging from the 40's to the low 60's; mostly due to a neighbor's dang tree. But while he's here maybe they can bump the Sony receiver from the office.

    It doesn't work that way.
