View Full Version : Bad multiswitch or dish?

I have an HR10-250, HR20-100 and HR20-700.

On Saturday tuner 2 on the 100 went out. The 700 was still fine. The 100 is new, so assumed it was just a bad tuner, especially since I swapped the lines and tuner 1 still worked and tuner 2 didn't. Directv shipped me a replacement for it (a 700) and I see same problem. Tuner 2 doesn't work. I then moved the 250 to the failing location and it fails. I then move it back and it still fails. I tell wife and she says she noticed it was hung (but she didn't tell me) so I guess it had a problem that I wasn't aware of (I don't usually use the 250).

The 100 and 700 just show dashes where they should show signal strength on tuner 2.

When I run setup on the 250 it shows strong signal strength on both satellites, but then says for both satellites:

101 (a) Right side not detected
119 (b) Not detected
110 (c) Not detected

I have a Zinwell WB68 and a Slimline. Is this likely the switch or an LNB problem?

Thankfully, the old HR20-700 continues to work on both tuners.

Any advice before I call Directv?

It's starting to sound like bad cables from the Zinwell.
If you've got the -700 working fine, then the dish shouldn't be it and if you think the Zinwell is it swap the cables from the non working -100/700 over to the working-700 to see if it's the output of the Zinwell or the cables.

I don't see it being bad cables. The HR10-250 and the HR20-100 are in different rooms. Can't see the cables to different rooms going bad in the same couple of days.

try switching the cable's to different known working ports on the WB68, if the problem goes away, i would say it is the multiswitch going bad.

Do you have a splitter or a combiner in line? Also I had trouble like this and it was a bad Barrel. Check your grounding block. Try to bypass your grounding block with a good working barrel.

Bad: BBC, cable, connector, external multiswitch output, LNB internal multiswitch
output.

With no diplexing involved and 2 receivers tested on the same cable runs; those are the possibilities listed in descending order.

With a "working" box I'd think the LNB internal multi-switch could be ruled out of your list.

Agreed;

My logic tree (at least in my mind) was to check BBC's, connectors, then cables. If these checked out, bypass the external multiswitch. It was at this point that I ran a new logic tree, with the external multiswitch excluded, and introduced the already contained (the embeded multiswitch outputs) element.

In other words, I over "thunk" it. :D

Can the multiswitch in the dish support 4 tuners? If so, then I can just take the 250 out of the picture and if everything works then I would assume it's the multiswitch and just get a new one from Solid Signal.

The dish can directly feed four tuners. You can remove the WB68 and use barrel connectors to connect directly to four tuners (two dvr's).

That is very sound logic. !devil12: Shoulder :angel:

You win. Bad connector on grounding block.

"Score one" for the logic tree....

Thank you folks, "WE" will be here all week and don't forget to tip your servers.

You win. Bad connector on grounding block.

Cool what did I win? I am happy it was something easy. Good job on finding it.

Take care
