I think I lost one tuner, but...

I think one of the tuners on my HR20 has died. I noticed last night when I tried to schedule a recording, and it had a conflict. Usually it shows me the two scheduled recordings, and lets me "Cancel 1" or "Cancel 2". This time, it only said "Cancel 1".

I went to the setup menu to test my signal strength. I looked at a couple of satellites, and got very high signal strengths (in the 90s) for both tuners.

Then I switched to "signal meter" mode. I got 97 on tuner 1, and nothing on tuner 2.

I swapped cables and BBCs, and still got 97 on tuner 1 and nothing on tuner 2.

If my tuner is dead, then why and I getting excellent signal strengths on both?

Try, when nothing is recording, setting up two one time recordings in the guide at the current time and see if it works.

You might try doing the recordings on two SD stations first and then two HD stations.

If you havn't tried it yet. Do a reset and see if that brings it back.

I looked at a couple of satellites,

check all sats for signals, not just a couple. I had an lnb acting up causing similar issues.

How were you able to diagnose it to a problem lnb? Ive had this problem on mutliple ird's in the past year both HR20's and HR21's and initially thought it was the ird since all the other ones had no trouble. I eventually changed out everything from the ird to the wiring, the switch, the dish I still ocassionally get the error, i get it much more often on the basement tv than any of the others but i get it on 2 ird's out of the 5. I used to get it on the the kids tv but since swapping that unit out I haven't seen the error yet there.

After all the reading ive done on the software issues i was hoping i finally found the answer.

moving receivers showed me that 1 specific feed was consistently having intermittent issues. I took my wb616 out of the loop so no other switches were involved. I then moved that feed line to a different output on the lnb and found that that feed then worked. the feed that was now on the original suspect output started showing sporadic issues. it took some time to narrow it down since it was sporadic errors but once I was able to determine the feed that had issues more often than others it got a little easier.

A reset has solved the problem; I am now back to two functional tuners, both of which are showing 95 on the signal meter.

I got hit by the "every HR box in America is locking up" problem also, but that seems to be OK now.

keep an eye on it, resets always temporarily cured my issues but it always came back.
also, very close to the time (about a week before) my LNB acted up I did actually have a hr20 tuner 2 die. this one was signals jumping, while watching, from 0-100 and back (wildly swinging) and never stabilize. resets only helped this issue for 30 minutes or so then it started all over again. was never able to figure out if one issue made the other worse or not. after replacing the known dead hr20 I was able to narrow down the lnb, forgot to mention that at first.
