Ever Since I switched from Direct TV to Xfinity my TV freezers when using the X1 DVR. I have to do a complete reset on the X1 and then everything is good for a day or so then it comes back. I have spoken to Sony and they went through everything on the TV side and they find no issues, I have had an xfinity tech out and he replaced the X1. but still have the issue. I am at wits end.
A recent software/firmware update pushed on the X1 platform a month or so ago created some HDMI handshake issues, especially with Sony TVs. What you're seeing could be realated to that, but it could also be signal levels since you're newer to Xfinity. If it freezes and gives no error messages (and you still have audio), that may point to the HDMI handshake problem. Do you have any pattern of when you see the frozen screen ... when you turn on the TV? when you switch inputs? It may help the troubleshooting if a pattern is seen.
I know I found with my Sony that if I turn off the TV on an input other than the X1 box I will lose the X1 signal and have to reboot the X1 box. I have to make sure to tune back to my X1 input before I turn off my TV.

I guess the X1 did an upgrade which recently caused this. It is connected to the main X1 recording box with a monster ultra HDMI cable. Power saving is set to "off". Only fix is powering off X1 box and then waiting 4 minutes to watch TV. On the 3 other TV's in the house using remote boxes they all work fine even when the main box and Sony aren't communicating via hdmi.
Same thing started happening to me about a week or two ago. I have a Sony KDL800B that's ~ 4 years old. It definately appears to be an HDMI handshake issue that popped up with some sort of X1 software update. I noticed these issues when my software version started jumping to 87.1.3 up to 88.x ... my software version is now back to 87.1.3 again and still having the issue. I've had my X1V3 (Arris) box for a while and never had issues.
From troublshooting ... If I stay on my X1 HDMI input I have no issues. If I switch to another input and turn the TV off, when I turn it back on after a few minutes I get no signal on the X1 input. I need to cyle the X1 power to get a signal back. Switching inputs does nothing. BUT, if the power remains on for my TV, I can switch inputs and back to the X1 input later and it does not lose singal. It appears the HDMI handshake issue occurs when the TV is powered down when NOT on the X1 input. Atleast that's what I think is happeneing with my Sony TV.
As others report, this was not an issue until the past week or so, and I noticed the X1 box has been getting updates with the version # jumping around. This is something on Comcast's side and also appears it may now be affecting other some other brands as well (Vizio?)

Just started happening to me this week, and has happening two days in a row. For me, when I turn the TV on in the morning the TV picture is frozen ... one morning the audio was working, and this morning the audio was out as well. It's only happened overnight. I've got a new Arris AR AX013ANM that has great docsis signal levels via the diag page and comcast confirms my singals look good. Also don't think it's a HDCP issue as I don't need to reset my box. I just need to change the channel and it will start working again. This started this week when along with a recent update to the software so I think some (obviuously not all) of the freezing issues may be related to the newer software update ... I know this newer update adds the ability to select when you want your daily updates/reboots pushed.
At the same time my X1 box stopped promting to delete recordings after watching, which others have seen this same issue this week
