Sunday night I lost my HD locals on my HR20-700. The SD versions were there, as were all the other HD channels. I know there were there at 4 pm, as I had the Redskins game recorded on it. I called DirecTV and went through the whole reboot/unplug checklist. Finally we were about to schedule a service call when I got disconnected. I let it go and decided to see what happens - I have an OTA antenna and an HD TiVo, so I'm still covered.

Monday, the locals were back. Weird. Then Monday night they were gone again. Occasionally the unit will start to show a picture, but it will immediately pixellate and freeze.

I'm thinking this is a dish alignment issue. We've had some decent winds lately, so maybe it was barely in alignment before and now it's barely out of alignment for that sat.

Agreed?

Welcome to DBSTalk

Is it happening only on your HD locals or all HD channels (MPEG4 and MPEG2)?

What are your transponder signals on SAT 99b? Please check during the day and night and post here.

If you are having problems with your other HD channels please post your transponder signals on SAT's 103b, 110, and 119.

Thanks for the reply. Yeah, it's only the HD locals - both the older MPEG2 and newer MPEG4 HD channels seem OK.

I'll follow up with the signal strength info. I looked at it Sunday night, but I wasn't sure which SAT I should be looking at.

Yep, post back your signal readings on 99(B) and 103(a). One of those is beaming your MPEG4 Local HD channels.

I did get the new VoD firmware update with the last week or so.


Here's my signal strength during the day (when I *am* seeing the HD locals):


1=87
2=79
3=87
4=79
5=0
6=34
(The rest are N/A)

I have had the same problem for over a month. I only lose the 4 local MPEG4 channels at night. Every other channel is fine and the locals are perfect in the daytime. DTV has sent out a 5 separate techs and has changed my dish, multiswitch, wall connectors, dish posts, and whatever else you can think of. My signal strenght has not shown any issues. Moreover, when the channels go out, all I get is a black screen; no searching for signal and, typically, no channel banner.

I have two dishes and, strangely, the problem only happens to the two HR20-700's on one of the dishes and not the HR20-100 on the other dish. The fact that it happens to both 700's at the exact same time lead me to believe that it was not a receiver problem, but perhaps it is a software issue.

I have no clue what else to do about this other than rip out the system and go to FIOS.

Those readings could probably be ~10-points higher, so your dish might benefit from better alignment. Let us know what happens to those readings tonight when you lose those channels.

This wouldn't happen to be proceeded by the Star Spangled Banner, would it?


:D

Don't mind me. Carry on.

I've had a similar situation before, I had to tweak the dish ever so slightly. My signals were better in the daytime.

Well I feel silly now.

Last night I went to check the levels and *all* the channels were gone. I triggered a reboot, and while I was re-checking everything, I noticed that the connection to the HD in-line adapter (BCC? Upconverter? Something like that) was loose. Once I tightened that, everything including the locals came back.

I guess it's possible that a slightly off dish alignment + a slightly loose connector was causing my problem. I'm not sure how the day/night part factors into it though.

I'll check again tonight.


For the record, the levels after re-tightening were:

1=88
2=79
3=88
4=80
5=13
6=35
