Massive Pixelation Every Night at 10:30
Can anyone guess why my Spectrum cable feed gets massively pixelated every night right around 10:30? It usually clears up by 11:30, but not always. It’s on ALL the network channels and many popular cable channels like ESPN, HGTV and SEC Network but NEVER on the shopping channels!! I’ve called Spectrum support but when they come it’s not happening and they are no help. It doesn’t affect my internet speed, just most of the channels I watch. I can still watch the channels fine on a Xumo box, but that’s harder to navigate.

Just curious if you could log on to your Spectrum account right when it happens and see if there are any relevant red-banner maintenance alerts and note that the TV app uses Internet which, in turn, uses different RF channels than the cable TV does.

This is in Smyrna, Georgia. I’m watching through a TiVo, but it’s not the device because it’s perfectly fine throughout the day. The last time I had a technician out, he said they would monitor my signal — but then, I never heard anything about that.

Seeing as how so many of the 6-MHz-bandwidth TV RF channels are all being disaffected the same way at the same time with such peculiar periodicity tells me that the root cause could be thermal temperature-related as in marginal to begin with and then beyond marginal when the TiVo Bolt is, say, downloading/updating the guide or whatever.

Heard that but unless/until the inquisitor is able to confirm a service group-wide issue, it would be easy enough in the meantime to take the cover off of the Bolt and/or direct forced air from a fan onto it just for determination purposes. I mean at least find out how contemporaneously hot the CableCARD is to the touch.

Last night, I did check the cable card during the pixelation and it was not hot. I’ve also tried to get info from my neighbors, but most of them go to bed before 10:30 so they have no info for me.

@TBarclay : Heard that. Now this:
🔗 Troubleshooting Digital Cable TV Signals :
↳ How to check the Signal Strength and Signal Lock? 🔍 👀
↳ How to check the Signal Quality? 🔍 👀
↳ Distortion and/or macroblocking ↳ "If there are no (or few) RS Corrected or RS Uncorrected errors, and their values are constant, you should troubleshoot to determine whether the issue is caused by your TiVo DVR, TV, A/V equipment, or cabling between the DVR and the TV. […]" 🔍 👀
P.S.: Feel free to share what you find out about e.g. signal strength & SNR & RS Uncorrected errors if you've a mind to.

Methinks thou doth protest too much.

Satch, thanks for all your suggestions. I have checked the TiVo Diagnostics when this occurs and the signal strength jumps back and forth between 100 and the low 70’s. The RS Uncorrected is showing 26379 and the RS corrected shows 784764.
I tried to upload a video of what this craziness looks like but it was not in an approved format.

Here’s a picture, though.
