Intermittent Pixelation on various channels
For the past several weeks, I have been seeing intermittent pixelation on various cable channels. The pixelation lasts for a few seconds and the audio will stutter. I have a DVR and one cable box and the TVs on both boxes are showing the same problem. If I look at the diagnostics in the boxes, they show good signal levels (0 db mv) and good SNR (39 to 40 db). There are days when I don't see the problem and other days when the picture is almost unwatchable. I've had no problems with the internet or streaming channels. When I called Spectrum support, the technician said that my cable drop needed to be replaced. We have underground wiring, so replacing the drop is a little more involved. Before I have the drop replaced, I'd like to ask if anyone has had this problem and was it resolved by changing an underground cable drop?
