I have pixelization on some channels and technicians have been here 5 times in the last 10 months. When they fix it the problem comes back in about 2 days. Comcast told me to have an electrician change my cable lines so I had one come out and he said if he re-wired my cables it very likely would not fix the cable tv pixelling problem. When Comcast techs come out they change fittings and boxes and again the problem returns soon after they've left. Last time they replaced things in the ground in the box at the sidewalk but again the problem returned in 2 days. When I stream on Netflix and such it doesn't happen - it only happens on some of the cable channels. The pixeling is so bad you can't see a picture and even the audio is inaudible so it's not possible to watch the news on Channel 703 KCRA Please help!
