Missing channels on 1 of my 3 receivers

[Pinchhitter]

I am missing 2 Denver locals from one of my 311 receivers. I have rebooted the receiver using different methods (held the power button and also then tried unplugging) without any result. MY 2 others (311 and 811) receive them fine.
Anyone know why this happens?

I have that same problem with my 942, Chicago channels, 5 and 7 come up missing, but channel 2 comes in witch is on the same TP as 5 and 7... tp stright is in the upper 90's on that tp. Im wondering if HD LIL has something to do with it... to me its not a big deal as i get those channels via ota anyhow.

Is this happening only on your BIG 4 locals (ABC/CBS/NBC/FOX)?

Because its happening to me too, only on my 811, all 4 go red, says need checkswitch etc (its bull) but then there back hours later, reboots etc dont matter

Same thing on my Dish411. Big 4 Only on the lower channels.

It is only happening to ABC and Fox from Denver, and it is happening on a 311 receiver. These are distant networks. I have no problems with the other 311 or the 811.

Have you tried swapping the two 311s to see if the problem moves with the box?

That's the first troubleshooting step.
