I haven't had the problem in a while, but it hit today.
Middle of the day, only one thing being recorded. I believe there was a channel line-up change from the messaging center. All channels went black on all tuners with a signal problem message. Reboot required.
Stock Premeire XL, no tuning adapter, FIOS for cable.
I think you mean uncorrected and corrected right?
I would say the 2361 uncorrected errors look rather unhealthy.
But to be fair, it depends on how long you had that tuner on that channel.
If you scroll down, it should tell you how long that tuner has been on that channel. Try forcing tivo to record 4 different channel then what it's on.
Wait an hour go back and check on the error count. If you have double digit error counts in just 1 hour, I think it's not healthy.
Is the tivo getting the cable connection through any splitters? How is the quality of the cable used to connect.
What signal strength is it reporting in the diagnostic screen?
Watch the tuner 2 and 3 error counts for a few minutes. If you have uncorrected errors that are incrementing it indicates you have a current signal from that channel that Tivo is not able to process correctly. I would try a soft reboot(under help in hd menu) and look at the error count on those channels again. If the error counts are incrementing it is likely you have a weak/dirty signal. If the error count is not going up then Tivo is processing the signal OK which makes me think that it was Tivo as the reboot fixed it OR the signal got better during the time you rebooted which is quite possible if the channel is SDV as it may now be on a different frequency. Maybe if you can repeat this a few times you can determine what is going on especially if channels are not SDV. If you have other tv's tuned to the SDV channel(s) in question, Tivo should get the same channel on the same frequency after the reboot as that channel is locked to a frequency for the other tv...
Same story. Lost signal to all channels again today. I was watching the NCAA tournament games, switching between 3 games that were airing. The Premiere was recording on one tuner. It lost signal repeatedly. I did a soft restart 2 times and reseated the cable card 3 times. After I quit switching between games it settled down.
Another of my units had the problem last night.
After a reboot the problem occurred again a few hours later.
I took pictures of the DVR Diag screens, and the /var/log/tverr.
The problems seem to happen at the same time as the "Time Since OOB Tune Start time".
So it seems something cause the OOB to reacquire an OOB lock and retune, which should be OK but the Tivo never recovered.
The Tivo also noticed the problems from the inputs in the log file, but no problems on the DVR diag ( RS numbers were 0 ).
You guys should follow this thread as well:
There seems to be a fix for this. I just got it downloaded to my 4 tuner model and testing it out now. Stay tuned.
Is the fix only for those with TA problems ?
I actually dont think its about the tuning adapter, but its the tuners themselves. The 4 tuner model uses new tuners that werent used in the 2 tuner models. But thats just my opinion about it. I've tried to get Tivo to explain to me what this fix does, but the people in level one tech support said they dont have that information. When the "fix" was ready for me to download, I just got an email from someone at level 2 tech support telling me to download the fix and test it out for the next 48 hours and then report back. I've left a message to ask what the fix does, but no one has responded to me yet.
So far so good. I havent had a lost channel since I downloaded this, and it seems to be rock solid which is shocking to me after all I've been thru with the 4 tuner models. I've never been able to keep one of these Tivo's going without rebooting them every few hours. Around 9pm central time tonight 3/28 it will be 48 hours. So I'm shocked and a bit impressed
I did this and the only issues were tuner 0 (0/52) and tuner 2 (6865/1309).
Nope. The cabling looks fine to me but what do I know. I've had FIOS since 2008 along with first a Tivo HD, next a 2-tuner Premiere and finally the P4.
Lowest is 92
Thanks for you help.
Grrrr. We have a 1 week old XL4 that has started doing this. All channels/tuners go grey. Only a reboot will fix it. We have a new 75hr Premiere as well and it is having no problems. Both are stock, FIOS, no TA. All the stats on "DVR Diagnostics" look reasonable, even while it's happening.
The first clue the first time, since we weren't watching live TV, was that a show streaming from the Premiere to the XL4 was pixelated. As we tested, we saw that live TV was grey on the XL4. After the XL4 rebooted, the show streamed fine.
We need a fix. We are not happy with our expensive new toy.
had simular problem until the cable card was replaced then all channels were back
So it looks like tuner 2 has issues with uncorrectable errors, tuner 0 looks ok.
The next step that I suggest is to write down the channels that you were tuned to that gave you these results. Then you can swap the channels that are on tuner0 and tuner2. This way you can confirm that the problem is not with the particular channel having bad reception, but it's your tuner that's getting error. I suppose you could have a tuner that's more sensitive and can't receive signal properly unless it gets higher signal/noise ratio than normal.
Happened again last night. That's 3 times on a 10 day old XL4.
3 tuners were grey. 1 had a few small mpeg blocks showing through black. I looked at 'DVR Diagnostics' and the stats for all 4 tuners (which were still recording), were roughly:
RS Uncorrected: 0
RS Corrected: 0 (1 for one tuner)
The CableCARD Status, Pairing and Conditional Access menus all said
"Failed to load CableCARD /cp/auth" or something similar.
I removed and reset the CableCARD and it started working. No reboot necessary.
bobdole888, I did the swap and this time I got 0/0 for both tuners 0 and 2. I don't know what this means. I haven't experienced pixelation and blank channel the past two Sundays which is good. However, I did restart the Tivo that first Sunday prior to the time my recordings started. Someone previously suggested that this would prevent the issue from arising that evening and so far it seems that they are correct.
Anybody hear anything new about this so-called fix that Tivo is pushing to select folks? Is it only for people that have TAs/SDV or anyone whose getting blank channels?
Another lineup change on comcast this weekend - another "this channel not authorized" on every channel. It may be time to resume work on the script I was writing to telnet into the tivo and reboot it so I can just make it reboot every day at 4 AM...
As far as I know, I dont think its only for people with tuning adapters. Engineering told me that its a bug in the software, and it will be included in the spring update, so everyone will get it.
Since I've gotten the script I have had no lost channels, which is really shocking because I've never been able to go for more than a few hours without the "lost channels bug" biting me.
Now I just wonder when the spring update will be out.
How did you know that they updated your machine ?
(Is there any indication that you have this patch ?)
Did they push the patch during a standard call ?
Did you have to reboot your machine or did they reboot for you ?
I was notified by engineering that the script was ready for me to download, and I was told to go to my Tivo and connect, and I could see something large downloading. It took about 10 minutes for the script to run after the download completed. There was a couple of suggestions that were recording at the time so a couple of the red lights were on the front. Once the script started running the tuners went "dead" and the lights went out. After it was done I unplugged everything and then plugged it all back in. Someone else that got the script before me told me to do it that way, engineering really didnt say much. I had written to them a couple of times back and forth because I wanted to know more, and they guy just told me not to change anything as far as switching the hard drive, or doing a clear and delete, or to rerun guided setup until the spring update came out, because it would be included in the new software.
As far as knowing I have this, all I can say is that I've never been able to use one of these 4 tuner models before, more than a few hours at the longest. I got this script on Tuesday 3/26/2013 at around 9pm central time. After getting this I havent had one failure. The Tivo has been up and running since that day and time, which is a miracle for me. And then I have the emails that were sent back and forth between me and engineering that say they were pushing it to my Tivo.
Happened to our new 2-tuner Premiere now, as well as the new XL4. This is so much fun.
We had HDs on these same cables with the same CableCARDs for years and never saw this. We only upgraded because FIOS is changing some channels to mpeg4.
