How did you get a live person? I've spent DAYS on the phone just trying to get an agent to speak with me. When they said they would call back when available, I got an extended ringback. I have 2 channels that are completely pixelated. So, obvi this is a COMCAST issue; my device works perfectly otherwise. NONE of the suggestions have worked for me. Congrats on getting through at ALL and for also getting to speak with someone knowledgeable. COMCAST NEEDS TO SUPPORT ITS CUSTOMERS. This has been going on for weeks. Just reply to every customer here and fix their issue. If it is a "line signal" per this person who got thru, just fix it! BTW: Exit, exit, exit 720 does nothing but take me to channel 720.
