Okay after waiting 12 days for Directv to come out and look at our setup here is my story.

The tech arrived at about 8:15. He immediately changes the multiswitch and that does not work. So he comes in and tests out the tv downstairs which is where our HR20-700 used to be and our Samsumg Directivo unit upstairs. Both are unresponsive and not detecting any signal.

He brings in a brand new (not a refurb) HR21-100 (black unit) and hooks it up in the basement. I was actually dreading this because Directv sent me this until because my HR20-700 was locking up all the times. The black unit would constantly give me a 771 or 711 error. So I sent it back to Directv and hooked up my HR20-700 again. So the tech procedes to install the new HR21-100 and sure enough it does the exact same 771 error. I had never experienced this with my HR20-700. However, the channels are coming in and the Directivo upstairs is working.

He checked all the signals coming into the house and they were fine and to the multiswitch was fine.

So after the tech saw the 771 error he goes outside to adjust the dish which made no difference. Only some of the channels were coming in. He comes back inside and says the reason I was getting the 771 error on the HD channels was because there were trees partially blocking the signal. I told him that I never had any issues with and HD channel when using the HR20-700 receiver. I told him that it had been working fine since last Sept. and only had and issue with the receiver locking up a few months agao and then the no signal issue after the electrical storm almost 2 weeks ago. He could not explain why it was working with the older box and not the newer one. I don't think it was the trees because when they originally installed my HD system they said the trees were okay, but to watch them (and pointed to a specific section) and if the branches grew a couple of feet they would need to be cut.

So after everything was working I left to go to work around 10:00. I came home and the HR21-100 in my basement is all 771 errors. Both regular and HD channels are not coming in and there is nothing but a gray screen. However, when going upstairs my Directivo is working just fine. Does anyone know WTF is going on with the unit downstairs? I am to the point where I am ready to call Directv and cancel, take the early termination fee, and go with Dish Network and hope the can provide a better HD experience. I have never had so many headaches and problems with Directv until I decided to take the HD plunge

try this, take a long cable and hook it up to a cable that feeds the multiswitch. run that cable to the back of the hr2x receiver and see if that helps. if it does, you have a bad cable between the multiswitch and reciever.

dumb question, but have seen this before. are there 4 lines going to the multiswitch?

make sure that there are no splitters between the multiswitch and your receivers.

Can you please detail the installation.

A couple of things could be wrong here. Either the cables are bad or the LNB's could be going out. Since he replaced the Multi-switch that probably rules that one out.

What type of Satellite dish is it, AT9, slimline, etc?

There are 4 lines going into the multiswitch and 4 going into the house. Two are going to the HD receiver downstairs and the other 2 are going to the Directivo upstairs

Slimline. I don't think the cables are bad because he hooked them both up to this little device and didn't say anything.

if you can, take 2 cables hook them up to your multiswitch and run them to the back of your hr2x receiver.

if not try swapping your receivers around and see if the problem continues with your d*tivo dvr.
if it does, then the cables are bad, it could be the connectors or the barrels at the wallplate.

I don't have any cables to run. Should I be concerned for my Directivo? The tech said the old HR20-700 wasn't working and that is why he gave me a new HR21-100. So I am concerned about hooking up my Directivo because if something is somehow frying the tuners on the downstairs receiver then I would lose my Directivo.

I am downloading some pictures off my digital camera to post here.

The dish itself is a poll mount in our gravel driveway. The four cables coming from the dish are buried under the gravel. However, due to the nature of gravel, during the initial install I borrowed my neighbors back hoe to dig a trench and then had the tech run the cable through the PVC pipe I bought so the gravel would not dig into the cable.

The cable then runs to the side of our house to the multi-switch. Then two sets of cables have been run into the house. One set is for the Directivo upstairs and the other for the basement.

Just a quick thought since it hasn't been mentioned (unless I missed it).

Have you tried changing/swapping around/removing the B-Band Converters?

If those go out, I've read that all kinds of weird things can happen... that's why I have two spares sitting in a cabinet near the receiver.

BIG NO NO:

remove all of those terminations on the multi-switch
I'll try swapping them around. What are terminations? Are they the things that screw on where there is no cable? Not to sound dumb, but wouldn't you want those on the switch? They have always been on it since they did the install

"Simply" remove all of those "thingies" that are connected to where a cable isn't.

In the instructions that come with the Zinwell WB68, it states "Not to use terminations" on any unused ports.

The receiver(s) are driving the LNB [on the Dish] with either 13 or 18 DC volts, and should be sent to the terminations as these are nothing but a 75 ohm resistor, which is good for RF and bad for DC voltage.

I removed them, but it didn't seem to do anything.

101, 110, 119, and 103(c) are all at 0 or NA

Tuner 1 and 2 not acquired.

Again, the Directivo unit is working normally upstairs with both tuners functioning properly. I'm just confused as to how it was working at 10:00 today with a few 771 errors and now nothing.

I really want to try and get this fixed. I don't want to have to wait for another 12 days for someone to come out.

The "tech" that came out wasn't "the best", as those terminations never should have been used. The receiver may now be dead. Call DirecTV and explain today's service call didn't help. You shouldn't have had any 771 errors. The tech just wasn't "up to speed" on the job.

You can try to see what it does at your other location, just to prove it's not the cables to where it is now, but "my guess" is time for a new receiver.

Those terminations were on the original multi switch as well.

I think I have an idea of what is going on possibly. I went downstairs and unplugged the HR21-100 and brought it upstairs. When unplugging it I noticed that the B band converter in tuner 1 was very hot. Anyways, I unplugged my Directivo and plugged the HR21-100. I had to run it through the composite (Y,R,W) cables. It did not work. As soon as I unplugged one of the B band converters and screwed the cable directly into the tuner it acquired that signal. I did it to the other and it is working normally. There just is no HD since I am not using the B band converter.

I am going to try connecting it directly downstairs without the B band converters on it and then put one on at a time.

Does this sound like it could be the cause?

There are two other disconnected coax connectors in your picture, and it appears that they are very corroded inside the connectors. If the connectors on the coax that goes to your HR21 are equally dirty or corroded, that could be contributing to your problem.

As to protecting the unused ports on the WB68, yes you do want to put a dust cover or protective cover on them, but as VOS noted, you do NOT want the caps that have a wire in the middle (terminating resistors, which is what you have in your picture).

With those installed it is possible that either the receiver, or the multiswitch, has been damaged, as they result in a DC short.

There are situations where you do want to use terminators, but this is not one of them.

The tech did say one of the cables was corroded and cut it and put a new end on it. The two cables dangling in the picture are from the original small dish on our roof that is no longer used. If we want our local channels through our dish we were told they would need to use this dish, but we are not interested.
