I have had D* for about 20 months now. All of a sudden in the past couple of weeks I have been getting alot of "searching for signal" on my HD box. My upstairs SD boxes both continue to work without problems, but the downstairs one is out. Any thoughts on what this may be? It is an H20 (I believe the -600 version but don't quote me on that).

Check your signal levels on the 99 and 103 Sats. More than likely the dish has moved. The HD signals are delivered in a much narrower beam width and thus are far less forgiving on dish movement. This is why your SD units don't seem to be affected.

With constant signal loss, I'd bet you'll find your signal levels are below 50 on the 99c and 103c birds. Optimally, the signal strength should be above 90.

Good luck

My two H20-600's were just recalled and replaced, although I was having no issues. When I probed as to what the problem with them was, the CSR did not have an answer. Could potentially be an issue starting to show up with the box.

99% of these problems are caused by dish misalignment. Please post back with your signal readings for each satellite's transponders (and both tuners if applicable). You'll find these readings under "Menu" -> "Setup" -> "System Setup" -> Satellite -> "View Signal Strength".

Fill in your readings for each satellite and tuner using these examples. A properly aligned dish will show 80-90s on most of the relevant transponders (although some will be low or zero):

I'll post the numbers this evening after I get home from work. I have been reading other threads on this forum from people similar to me. Everything going along smoothly and now in the last few weeks some issues popping up. It very well could be that the dish has slipped out of alignment, I didn't think it would be this based on the SD boxes working fine, but the description above seems to fit that.

Thanks for the responses.

I'm having the same problem with my H20, it started about three weeks ago. I get "Searching for Signal" on several SD channels, including 550 IFC. If I do a system reset or unplug the unit and reboot, my reception on the problem channels is OK until I change channels and try to go back, then I get the "Searching for Signal" prompt again.

Minor dish misalignment will impact the HD channels (99 and 103º satellites) much more than the SD channels (101º satellite).

Again, thanks for the info., however reading other threads on dbstalk, it appears that there is a recall on the H20-600. I have posted the numbers below, but my next call is into D* to start the replacement process.

So as far as I can tell, signal strength is excellent across the board w/ a couple in the 50 range (possibly due to the defective H20-600?). When I call, which receiver should I go for? I have an antenna on the roof, but since installation all of my locals seem to come from D* in HD. I haven't followed the improvements of the H21/H22's other than the no OTA input.


EDIT: One of the people above said to check signals on 99c & 103c, I dont' show those two sat's on my list above at all??

Great signals across the board. Don't worry about those 50's. Those tp's are not pointed at you. 103(c)=103(b), and 99(c)=99(a) on the H2x's. If they ship you an H23-600 replacement, don't connect the BBC from your H20-600 to it. It already has one inside.

"searching for signal" or "searching for satellite signal" there is a slight difference.

I am all of a sudden seeing the dreaded 771 on only my HD locals and on only one receiver. No issues at all since install 8 months ago and just 2 days ago they are no longer showing up.

Details: I currently am set up with and HR21 upstairs and H21 downstairs. The
HR21 has no issues receiving locals in HD. I have checked connections, RBR'd, had the receiver reflashed by D*, and even moved the receiver upstairs and connected it in place of the HR21 using all of the HR21 cabling including one of it's BBC's. Still can't get my HD locals on that receiver.

Signals on 99a, 101, 103b, 110, 119 are all 90's

99B:
1-8 0 92 41 76 72 100 NA NA
9-16 NA NA NA NA NA NA 0 0
17-24 100 100 100 0 0 0 0 0
25-32 NA NA NA NA NA NA NA NA

103a:
1-8 0 0 0 80 0 0 NA NA
9-16 NA NA NA NA NA NA 0 0
17-24 0 94 0 0 0 0 0 0
25-32 NA NA NA NA NA NA NA NA

Any ideas?

Surprisingly, the woman on the phone on Friday almost wouldn't send me a box. She kept saying that she had sent a signal to my box and it came right back without any problems/delays. I explained to her that the thing runs fine at times and terrible at others (w/ the 771 message). After about 10 mins. of going back and forth, including her admitting that they are recalling the H20-600's, my signal ended up going away and the message came up w/ her on the phone and she finally agreed to send me a new one.

Also surprisingly, she said that they are sending me a brand new H20-600, I asked her if it was refurbed and she insisted nope, brand new H20-600. No sweat either way, just surprised that they weren't sending a refurbed H20 or H21?

As to the question above, I can't recall the specifics of the message, but it states that it is searching for signal, 771 message.

I was recently having trouble with searching for satellite signal. It ended being an issue with the cascading multi switches that I had. They put in some power passing splitters(??) to each of my multi switches and that solved the problem.

Would have been better if they would have just done a SWMline dish instead, but they won't do those for existing customers. :(

Happens on both my receivers. ESPN HD 206, HDNET, all NFL Ticket HD channels. It always says "771, searching for signal" on tuner 2. If I leave the channel tuned to those specific channels for about 30 seconds, the signal appears crystal clear with no further problems (unless I tune off the channel). I checked the signals on 99 and 103 and have 50 or below on all.

What are your signals on 99(c) and 103(c) on Tuner 2? Your dish is out of alignment. Alignment for the HD satellites is very precise. Your signals on 99(c) and 103(c) should be mostly all in the 90's.

I'll check my exact signals tonight when I get home, but from what I remember they ranged from 20's thru 50's. I went on the roof last weekend and checked the elevation and tilt. The tilt was fine but the elevation was off about 1 degree (based on the degree markers eteched on the dish). I did not see any markers on the azimuth so I didn't attempt to make any changes. Do I need some sort of signal meter for the azimuth or can I use the DTV receiver numbers?

You can definitely use the numbers on the receiver. If they top out in the 50s, you definitely need to realign it. You need to see at least 80s on the highest ones, if you want to watch it in the rain. You can go up and down the ladder until you get them fixed, but it's much easier if you have someone telling you if they're going up or down. First adjust the azimuth; if that doesn't help, then try the elevation. Be careful; the dish is kind of heavy, and it can slide down. If neither of those works, you'll probably need a professional to come out.
