1 tuner gets no analog channels

[jeffk]

Hello,

About a week ago I noticed one of my cablecards was not getting any analog channels, I didn't have time to mess with it until today. I called Comcast and of course they wanted to send a truck [with a fee of course], so I declined for now.

So I decided to remove the cable cards, and re-run guided setup. I still cannot get analogs on one tuner. I re-ran guided selecting cable only. I have the rf plugged in fine. One tuner get all the channels fine, the one that cannot get analog channels, can get qam channels though.

Did something go wrong with my tivo, or is this still possibly a comcast problem?

Please help.

Jeff

Any ideas?

Followup [hoping someone knows].

I took it off the cable splitter, and still have the problem.

Is it possible that I just have low signal strength? Is there a way to tell that for analog channels, i know the signal strength on the digital channels says 95, but it always has, so thats pretty useless imo.


Thanks,

Jeff

Have you tried removing the cable cards and then running guided set up? TiVo will work without the cable cards it just won't see your encrypted digital signals. At least you would have an idea as to what the problem might be. I hesitate to say it's a bad card because cards deal with encrypted cable channels. But if it works without the cards then it's got to be a problem with the cards, all though that really doesn't make sense to me.

Give it a try. Good luck.

Give it a try. Good luck.Wouldn't the OP lose the cableCARD pairing info? Or, does it stay the same as long as they are re-inserted into the same slot? Personally, I wouldn't risk it, since if a new data ID is created, it would require a truck roll for me, Comcast/NE.

I'm not sure. I had a tech come out and pull my cards once. He put them in the wrong slots and then we put them in the correct slots and it worked. However that wasn't after doing a channel scan with no cards.

You may have a point and I thought about that before I gave the suggestion. OP, be aware that this may happen if you try this.

I pulled them re-ran guided, and same thing, no analog on one tuner [it is a grey screen and usually says searching for signal]. So I am *HOPING* maybe its a signal issue [which doesnt help when i take the splitter out of the equation].

Just as a FYI, i put the cable cards back in and they pair back up fine, once rerunning guided [just made sure to know which card went in which slot].

Still the problem with no analogs.

Since Comcast is a bunch of retards and are charging for truck rolls now [RIDICULOUS imo], I am trying my best to avoid this, but seems might have to get them to come out :-(

Unless anyone has any other ideas. Or ways to test signal myself?

About a year ago, one or more missing analog channels was a common problem. (See this link (http://www.tivocommunity.com/tivo-vb/showthread.php?t=323265)). In my case, it was solved by a replacement TiVo S3. I believe it was eventually cured for most users by a software update.

It sounds like the TiVo might be bad. On a whim, have you tried unplugging the TiVo, waiting about 30 seconds and plugging it back in?

I pulled them re-ran guided, and same thing, no analog on one tuner [it is a grey screen and usually says searching for signal]. If you have no analog without the cableCARDs as well as WITH the cableCARDs, I concur with the others. Sounds like your TiVo is bad. As another test, hook your cable directly to your TV. If you get the channels, it would point to the TiVo.

I guess I'll call tivo. I thought the fact one analog tuner can get them but not ther other could be a signal strength issue. I've had the tivo for awhile now, and this only showed up 3 weeks ago, all was fine beforehand. If I hook up to the tv directly of course it works, as does 1 analog in tivo, that proves nothing. My cable modem also has been going out a bit lately, pointing to signal strength as well I thought. I know all Tivo is going to say is to send it back in, but i have alot of recordings on my external I don't want to lose, so thats a very *LAST* case scenario. I just want to know is it possible the signal strength is too low to pull in one analog tuner, or is that pretty much barking up the wrong tree?

Thanks,

Jeff

my second tuner gets a lower SNR (36db vs 32db) and sees many more RS Corrected/Uncorrected errors (in the thousands, vs 0) than my first tuner.

I'd call Tivo and ask, but dealing with their support people is somewhere below going to the dentist for a root canal on my list of things I love to do..

The tuners in my S3 are not symmetrical such that if there are low signal level problems, one will be affected more than the other. Normally though the signal levels are high enough so that both work fine.

But if your signal levels are borderline low, it is definitely possible for one tuner to work and the other not to.

My (new) S3 is exhibiting some tuner weirdness too. I don't have cablecards yet (yes, I'm typing this while waiting for the cableguy...)

upon powering up one of the tuners was displaying rolling diagonal bars on the analog channels.

Inside the box there are two wires leading from the Cable/OTA connector/hybrid/switch(?) box to two tuner cans. Swapping the wires between tuner 'cans', the rolling diagonal bars stayed -- which would seem to point at a bad tuner 'can' -- in my case the one closest to the front of the S3.

I figured I would wait and call Tivo this morning, but when I checked this morning the problem has gone away. (Yay for temperature related problems. :/ )

If the problem re-occurs I'll probably call and get a RMA...
