Bad LNB? Bad Receiver? What to check?

[sam_gordon]

I have a Dish 1k.2wa(?) pointing at 110, 119, 129. Two lines come into my basement, both go through diplexers out to two separate rooms, and hit diplexers again before feeding a Vip211 and a 612.

On the 211, Nick (I think Nick West) will more often than not severely break up. Lots of Macro blocking, and just bad pictures. I can tune the 612 to the same channel and it's clean. Changing channels on the 211 leaves the problem with Nick West (I can go to any other channel and it's clean, return to Nick West and it's bad).

The HDMI output of the 211 feeds a Sony AVR, and the AVR outputs HDMI to the Samsung TV.

I've eliminated the TV because other channels (and Xbox) are all clean. It's the same with the AVR. It seems strange to be a receiver thing. I (almost) eliminated the LNB because the 612 is fine.

I have power cycled the 211. This has been going on for a while, but I'm just now writing it up. I guess I can swap the feeds coming from the Dish, but anyone have other troubleshooting suggestions?

If you are getting 110/119/129 then it is not a Dish 500. It would be a Dish 1k.2WA

OK, changed it.

Might be a bad line, bad connector, bad seperator, bad diplexor, bad receiver... Many different options.

Move the 211 to the 612 location and see if it has the same problem. If not look for a cabling problem, if problem follows receiver the odds are very strong the tuner in the receiver has a problem.
