I HAVE TO UNPLUG AND REBOOT MY XFINITY TV EVERY MORNING!

do you have a 4K dvr ? and has this started happening recently ?

I have a 4K dvr and this has started happening for me too. This issue had gone away for a while but it seems to have come back for the last month or so.

For me even rebooting does not work. The only thing that works is - unplug the HDMI cable, reboot the box, wait for 5 mins and then plug the HDMI cable back in.

It is way above high time that either xfinity fixes this issue or just swaps out the boxes and gives customers ones that actually work.

what is the symptom that causes you to reboot? did you try turning off power saver?

@Rustyben 

The symptom is that when I turn on the tv and dvr to watch tv, I get a blank screen. My TV says "no input detected on hdmi". even when the dvr is actually on.

I can turn the turning power saver off for testing purpose but I do want to use the power saver.

the TV/set top box connection are not working together. the power savings for an older spinning hard drive (less efficient than SSD) was less than $1 savings if left in standby 24/7/365. the main unit is on all the time just turns off the interfaces (HDMI)

and clocks if any.

How do i correct this issue? I am having the same problem with my Phillips TV and my Xfinity 4k DVR box. When I attempt to turn on the TV with the xfinity remote, the TV will turn on, but there is no connection to the xfinity box. When I unplug the HDMI Cable (only) from the xfinity box and plug it back-in, with everything still powered-on, the picture appears.

under your X1's menu for power saver, is that feature turned off?

the power saver feature is turned off. 

@ComcastJK We've replaced our cable boxes and HDMIs. We've rebooted countless times. Any suggestions?

A new HDMI did nothing to fix the problem, FYI.

Can someone from @comcast help us? 

I'm having a similar issue.. it's gotten worse in the last 3 days, which is the first time it's happened 3 days in a row, which is why I got annoyed enough to create an account and reply. 

To be fully clear, let me clearly define what the issue is at least for me: unlike OP, it is not guaranteed to be every morning, it can happen at any random time when I turn on the TV. I use the "All Power" button on my remote, and the LED on both the TV and the box light up, so clearly both are detecting the remote successfully, but once it powers fully on, the TV has no signal. Nothing works, including unplugging the TV, or disconnecting the HDMI. or Even just powering both the TV and box off and on. The only thing that works, once this issue happens, is to reboot the box. In fact, I wouldn't care if any of those other options worked, as annoying as the issue is. The main reason I care so much about rebooting the box as opposed to any other workaround, is: if I am recording something when this issue happens, it interrupts the recording during the 5-10 minutes of the reboot. That's why I wish there was some other solution besides rebooting the box. And I record quite a lot of programs, so it's not rare for me to be recording something when this issue happens. I also want to add that I have a VIZIO tv, which I believe is a different TV than anybody else in this thread, so I'm pretty sure it's not anything to do with a specific kind of TV. It's definitely to do with xfinity if we're all recently having this issue with different TVs.

But the weird thing is, it can happen to me even if the box is on and I'm just turning on the TV alone. The original state can be:

1) TV off, box off OR 2) TV off, box on.

Either way, once I use the All Power button to turn the TV on, it has no signal.

I also read this whole thread https://forums.xfinity.com/t5/X1/XG1v4-requires-reboot-everyday/td-p/3134460 of people who seemed to have a similar problem to what we are having now. In the end, it seemed to self-resolve for OP, so it wasn't helpful 😞

Now to explain the full details of the history of the issue for me. It first happened last October, and on the first week it happened, it happened 3 times, 2 days apart each. I started to just assume it was going to happen every 2 days. However, it was happening around the time I started to develop some other weird issues, including slow response time of the remote when I pressed a button, so I was kind of paying more attention to those other more annoying issues, and I assumed the issues were connected. After that first week, it happened less frequently, maybe about once a week. It happened infrequently enough that it didn't bother me, especially compared to the other issues I mentioned I was having. 

Sometime in December, I called xfinity to send out a tech because my TV watching experience was becoming borderline unbearable due to how slow (minutes not seconds) response time was becoming when I was pressing any button on my remote. A tech came out, diagnosed the issue, and ended up needing to do a re-wire in the walls of my apartment because apparently the cabling that was there was decades old and had just straight-up gone bad. Now here's the interesting thing, after this other issue had been fixed, the issue of needing to reboot went away! So I assumed they were connected issues and both had been resolved.

No can do. In February, more than a month after the issue had not happened for a whole month, it happened again. Then, it started happening again with its original frequency of around once a week. Since the remote response time issue wasn't happening anymore, and that had originally been the much more annoying issue to me, I decided to just deal with the reboot issue and move on with my life. However, over the last couple of weeks, the issue has gotten more frequent, almost as if it is literally based on an exact mathematical model! I started keeping track of the days, and the time between occurrences literally dropped from a week, to 6 days, to 5 days, to 3 days, to 2 days. Then for about a week, it happened every 2 days, and now, the last 3 days in a row, SUN MON TUE, it's happened EVERY day, which is the worst possible. I guess for you guys, the other people in this thread, it's already been happening every day, but for me, who had been experiencing it only once a week, and in January I didn't experience it for a whole month, it's now become quite frustrating, especially like I mentioned earlier when it happens during a recording, and the reboot interrupts the recording.

I don't really know what I'm expecting out of this thread. I guess I just posted to follow the thread and get any updates that come out of it. I don't plan to call a tech for many reasons, not only because I'm not letting any strangers into my apartment right now due to coronavirus, but also because I'm pretty sure they'll just suggest swapping out the box, swapping out the HDMI, etc, things you guys have already tried to no avail. One thing I've learned about xfinity techs in the past is that if you can't reproduce the issue when they come to your apartment, they're not able to help you, and I have no way of knowing that I could reproduce it. Another thing is sometimes they are just guessing.

Anyway, given the increase in posts in this thread recently, It's definitely some kind of larger issue affecting many customers. Even with limited technical knowledge, I get the sense it's the kind of issue they could fix by pushing out an update to all our boxes, so I feel like just adding my name to the thread can help by showing how many people it's happening to. That's all I feel like I'll get out this thread haha, but I know that seeing a thread of people that are having the same issue made me feel "better" in the sense that "it's not just me". So if I can help others with my detailed explanation, that's another reason i wanted to post as well. 

Oh let me add something else I want to add that I just thought of, just for total clarity. Even though I said it's now happening every day, it's not *every time* I turn on the TV. I turn on the TV about 3 or 4 different times a day, and so far (fingers crossed) even since it started happening daily, it's never happened more than once in a single day.

I am wondering if I've been recently having a variant of this issue.  As I have a Samsung LCD HDTV circa 2009, I had chalked it up to being a TV issue, but ...

For 4 days in a row up through yesterday (4/28), the first time I would turn the TV on in the day (which is after an overnight, and having been idle for 10-12 hours), the TV would show garbled video (sometimes no audio, sometimes audio screeching), and then power cycle itself after 10 or so seconds.  After it would power cycle itself, video and audio would come up fine.  No matter when or how many other times I'd turn the tv off/on later in the day, everything would be fine.

Interesting however, after having the problem 4 days in a row, I did not have the problem today -- i.e., first "turn on" of the day was fine.

Though an older HDTV, it is hooked up to the Xfinity 4k box ... obviously receiving 1080p resolution.

@CousinEddie_0 I am the guy who posted yesterday.. I have experienced (even though I have a VIZIO) what you describe about weird audio, sometimes no audio, but it's very rare, not frequent as you describe your situation to be. It has happened just once in the last week. i do agree with you though that after one power cycle, everything is fine, whenever this weird issue has happened.

I would also like to report that after 3 straight days of no signal whatsoever, and needing to reboot the whole box, today, just like you, I had no issue either of the 2 times I have turned on my TV.
