    I was watching a football game on ESPN last week, when all of a sudden the screen blanked with a V52 error. I've spent the last 5 days rebooting, powering off, getting refresh signals sent from the cable company, to no avail. Right now, about 1/3 of my channels have a V52 error message, or are completely pixelated and unwatchable. The other 2/3 are completely fine. WHICH channels are experiencing problems seems to change from day to day. It isn't specific to SD/HD, Premium/Basic channels.

    I went though a useless troubleshooting exercise with Tivo, which pointed the finger back to the cable company. I called the cable company and wasted more time with someone that didn't know what a cable card was, much less a Tivo. The call ended with them scheduling a service call.

    My Tivo is about 4 1/2 years old, so I'm wondering if there is something that can suddenly fail that would cause these symptoms? Or perhaps the cable card itself?

    How does your cable card conditional access display vary from this one:

    Important is the VAL: and AUTH: results.

    I must say, poor reception is not usually related to the cable card. How about checking Diagnostics for Signal Strength. A value of 90% is good.

    I've seen TiVo's with too much signal that break up with pixelation.

    So, maybe consider trying an attenuator at the input to the TiVo to see if that helps.

    An attenuator can be simulated using varying size splitters, as well.

    Hmmm, my conditional access screens don't look anything like that, so not sure. It is a Scientific Atlanta card with a date from 2010...

    The closest I can find is on a Copy Protection Info screen, and for Auth Status it shows CP Auth Received"

    The Tivo tech asked for auth info on the Active Program screens, but it isn't there. He thought I had a Cisco card, which might be the problem.

    My signal strengths are 97 - 100% if I tune to one of the "good" channels. If I tune to one of the "bad" channels, it either shows nothing for signal strength, or it bounces around from nothing to the 50's.

    Thanks. When I installed it 4+ years ago, I did have to put some inline attenuaters to bring the signal down to around 92% or so. I just took them off in case that was the issue, but I guess not.

    Hmmm...if some channels are really strong and some are really weak, it seems like there's an issue with the signal you're getting from your cable provider.

    If you disconnect every splitter that you can and still get signal to the TiVo, what are your levels like?

    What levels are reported in the GUI to your DOCSIS Modem?

    I would say check your actual co-ax cable connection from the wall to your Tivo. My Roamio (with cable card) will get the V52 and the pixelation when my cat gets back behind the tv and moves the cable around. You can jiggle it and see it come back through various pixelated phases and then lock in. I've also seen it with 1/2 the channels as V52 but the rest are working but it was still the co-ax cable.

    Thanks all for your replies. The cable company sent a tech out, and he spent about 60 seconds with me before deciding that he couldn't do anything because he didn't know anything about TiVos.

    "Can't you just check my signal levels?"
    "No, I'm a contractor and I don't know anything about TiVos".
    "I'll disconnect the TiVo"
    "No, I'm a contractor and I don't know anything about TiVos".

    In the interim, I had started a YouTube TV trial. We decided we were happy with it, and we cut the cord. I was hoping to at least verify that my Roamio Pro was OK so I could sell it, but we didn't get that far.

    My pixellation issues would show up on low-frequency channels, but not on high-frequency channels, and most often when uploading something using the internet. it's always a consequence of damage to the line coming into my house, likely by squirrels. Happens every few years, it's infuriating. So, anyway, if you have symptoms similar to that then it may be the signal coming into the house.

    I am having the same issue with my Roamio Pro, after reset, now I cannot get any signal at all. I know the signal is good as my internet is working. Not sure what had happened. I was having the exact issue of pixelated. I feel like Comcast is killing Tivo receiver or something.

    Pull the power on your TiVo for 3-5 minutes and then try it again.
