Had my 811 installed a few days ago. Generally works pretty well, tho I am growing a bit tired of all the "Check Switch" procedures. Anyhow, the receiver is located about 10" below my Panasonic CT36HX41. When it is plugged in to the power source, the 811 introduces a noticable amount of 60hz hum into the TV audio -- when I try to watch output from the 811, the hum is even higher into the TV, Denon AVR, or whatever. Is this a known problem, or do I just have a receiver with poor shielding?

None here. Sound like maybe a grounding/sheilding issue. Check your audio cables- you using optical audio? If not optical- try unplugging just the left channel- still hear the hum? Then try just the right channel. Do you only hear it with both connected? Replace the audio cables and double check your connections. Thats an issue Ive never seen nor heard of in any forum w/ the 811.
 
I had a similiar problem with my 811. Tried just about everything I could think of without sucess. When I tried it on the bedroom TV it worked just fine. I moved it back to the Home Theater and changed satellite feeds to the cable feeding my 5000 and it went away.

This has nothing to do with your questions, but do you mind if I ask where you are located that you were able to get yours installed, and how long you had to wait from when you ordered to when you got it installed...

I', in Albany, NY. Install was less than 48 hrs. after purchase. :)
 
No issues with my 811 at all actually. I am in northern NJ and took about 2 weeks (only because I needed a Sat. Apt). Showed up 1st install date, no problem. Dish installers (not local contractors) said they had a shiopment in the day before and most were gone already, said they are real popular as we already know.
I am really enjoying mine.

Ditto. 2 weeks.
 
Hum is still there, and the "Check Switch" message comes on 4-5 times a day. I called Dish and they are sending out a replacement -- We shall see how that one works!

It could also be the dreaded "Ground Loop". If you have equipment with non-polorized plugs, try flipping them one at a time and see if it changes. Also, try disconnecting the coax cables one at a time and see if the hum goes away. If you find that this is the problem, you'll have to bond the ground rods (which should be done anyway).

Around here, that's a "wait til thaw" issue...
