    Hmm... do you have a TWC box in the house? If you can tune one of the TiVo missing channels on the TWC box and then go into diag mode and see what the frequency is and then compare what frequency TiVo is trying to tune. With signal lock=No it suggests that there is no RF on the frequency that TiVo is trying to tune.

    Perhaps.

    How would I view Diagnostic mode on a TWC box?

    From my archives on Cisco boxes... this is a bit old but may work...

    Diag Mode

    On the box, hold the volume + button and the info button at the same time until it pops up on the screen.

    If it doesnt work... you can probably google the box model and 'diagnostic mode' and find out how.

    Tech came and went. Problem is now worse. I was missing 2 stations. Now I'm missing 20+

    Signal strength is excellent. Frequencies came in on the missing channels on his meter device thingy but it shows no frequency on the TiVo.

    He suggested a new CableCARD and/or SDV adapter, neither of which he had.

    Like 99.9% of the other issues I'm positive the problem is on THEIR end and they don't know it.

    So frustrating.

    God I hate that company.

    Mine sometimes does that. I have to power cycle Tivo with TA adapter powered off. Then power up TA and let it go thru its thing until it stops blinking.

    Power cycling the TA brought back the channels that went missing last night.

    But I'm still missing the original 2 stations. Just 2. That's not a TA problem... if it was I'd be missing ALL SDV channels.

    So I'm back to where I was earlier in the week... unable to tune 2 stations.

    Their Twitter "help" desk wants me to call the number... same number I called earlier this week and all they did was schedule a tech. Same number the tech himself called. So why would I call them a THIRD time?!

    Aside from that the "help" desk wants to schedule another tech. I guess the 2nd one will be better than the 1st? Why can't they send the good people the first time?

    Stupid, stupid, stupid.

    I very well may cut the cord over this this summer. I'm sick of their *****.

    Back in post #5777 you had an image of DVR Diagnostics showing signal level too low to even show up as a measurement. I know from personal experience you can have just one or two channels (actually QAM frequencies) that are too weak even though all the others are strong. In my case it occured for whatever channel was assigned by SDV to QAM frequency 543 MHz. I was totally convinced it was a problem with one of their QAM modulator units. On the second service call I was able to show the tech my Diagnostics screen with a channel on that freq and the low signal level (and severe pixelation). He was then convinced it was a problem outside my structure. However before escalating it he took the precaution of re-tightening the cable connections in the tap box at the corner of my lot (cable is underground here). And that fixed it!!!! Problem has been gone for two weeks now.

    During the phone call that resulted in this second service call the rep told me their policy was not to escalate (i.e., to more capable tech people) until there were three service calls for the identical problem! I assume such policies exist because the typical service problem does NOT involve a Tivo and typically will be solved, at least by the second service call, using "ordinary" field technicians. And because their supply of better techs is extremely limited.

    In general keeping my TiVo going with TA and TWC has been an ongoing hassle for almost four years now, although things have improved slightly over the years. I've slowly been building up my readiness to cut the cord, including OTA with antenna, Google TV with Logitech Revue, Netflix and pyTivo with a PlayOn plugin. There are free plugins for PlayOn that provide substantial live sports event coverage and live cable news channels such as Fox News, Fox Business, CNBC and MSNBC -- although video quality varies from barely watchable to comparable to standard definition. Many, many movies too.

    Thanks for the info.

    On my two missing channels my signal level is ZERO when looked thru TiVo. Not low or pixelated. Zip zero nada.

    Tech checked my signal on his meter thing and every channel is decent. Every one.

    That tells me that TiVo is looking for the channels on the *wrong* frequency, no?

    The tech didn't know - and had no way to find out - what frequencies those 2 stations are on (TiVo doesn't show it because it can't find it at all).

    I was told it could be escalated after my 2nd tech visit.

    Note I edited my previous post after you read it. My worst missing channel sometimes had zero signal also so I wouldn't rule out a poor cable connection. TiVo tuning an SDV channel to the wrong freq is a common SDV tuning failure problem which happens on Series 3 and 4 boxes. It has been well known (including to TiVo) for years. If you can get a channel tuned well enough to show a frequency in DVR Diagnostics, then in TA Diagnostics go to SDV SESSION INFO. One of the two sessions should show the same frequency but neither will show it if it has tuned the wrong frequency. BTW the session info also tells you whether the channel is SDV. Look at SamSvcid/Type. Switched for SDV, Broadcast for non-SDV, n/a for antenna channel.

    Are you saying that the diag page doesnt show what frequency its 'trying' to tune?

    I believe that any problem in a coaxial cable (bad connector, kink, squirrel damage, whatever) can change the impedance at that point and cause part of the signal to be reflected. Those reflections can sum with the main signal to essentially cancel it, but only for certain frequencies that depend on the length of cable involved.

    Yes, it just shows a dash.

    This is on the CableCard screens, when tuned to one of the non-working channels.

    The tech checked my signal levels and said they were more than good. He went thru *every* channel with his meter and everyone showed good strength... even the 2 that don't tune.

    We wanted to try a TW cable box but of course he didn't have one with him. Naturally.

    Well, this takes me back to the channel map statement. If the channel map entry is messed up for those two channels, and have invalid frequencies.... that could explain it.

    Another thought... if these two channels arent SDV... remove the TA and power cycle the TiVo and see what that does.

    Yep.

    I've suggested the channel map to their twitter support twice now and BEGGED them to do some investigation and all they do is offer to send a tech.

    The tech yesterday - while super nice - had no clue how the SDV adapter box worked so the concept of an incorrect channel map would have been completely foreign.

    Looks like I'm going to have to suck it up and have a 2nd (likely pointless) tech visit before they'll actually start thinking outside of their scripted responses and get someone higher up involved.

    Well there you go...
    With sensitive electronics always suspect cables and connections first.
    They should be inspected, cleaned and tightened or replaced when practical.

    In addition to having to power down my TA overnight on a weekly basis, I have a similar problem where a small handful of channels disappear on a semi-regular basis - about once every three months. In those situations I call TWC and get them to send a hit to my cable card and TA, reboot, and then all is good.

    It's a ritual now. It's always on a weeknight during The Daily Show when it happens. I never get the same tech but I've been able to get them to play along every time.

    Make sure they validate that the cable card is authorized for the missing channels. I've had that happen before too. (Random channels were deauthed for some reason).

    Is pixelization usually caused by an issue with the cable signal or the TiVo? I have Time Warner with a Premiere and for the last several days, I have been getting a significant amount of pixelization. This has never been an issue previously, but it is now so bad at times it makes it difficult to even watch a program.
