Samsung TV not recognizing Xfinity box

I have a Samsung Smart TV bought beginning of 2020.  I had hooked it up to Xfinity wireless box Xi6A, and it worked fine.  

However, now all of the sudden I can not get the TV to play cable channels.  I have no problem playing Netflix, Amazon Prime, etc…BUT, it does not recognize the cable box in the HDMI 1.  I tried to move to HDMI 2 and still same problem. 

I have done a hard reset, unplugged everything and then the cable worked…. But as soon as we turned it off and tried again, same problem….not recognizing the HDMI 1 and allowing us to watch cable.


Any thoughts/suggestions?  Thank you!!

Has there been a fix released about this? I have a new Samsung TV and we got a new cable box and the cable box loses power and takes approximately 15 mins to turn on again. This has happened about 10 times already and I set up my new box around 3pm today. Thank you.

Hey @user_453d09, thank you for reaching out to us on our forums. Is the box actually powering off or just not showing on the TV? If it is powering off, then there is probably a power issue. Testing the box on a new outlet would be the first step I'd try. The original post is probably a different issue as it seems related to the HDMI pass off and not power.

Last night I posted a new question with 3 Xi6 problems, one of them similar to this thread.  I was looking forward to an Xfinity tech jumping in and giving me a solution to my 3 issues but after reading this thread, I won't hold my breath.

I found a workaround for the one similar to this one and if it can help anyone else, here it is:

My problem: if I turn the TV off, after a few hours when I turn it on, I get NO SOUND and NO PICTURE.  When I say "no picture", I mean no programming picture (no live TV); if I press the Xfinity button I do get the menu on the blank black background and interestingly, I discovered that if I use the menu to play a recorded program, both picture and sound appear for the recorded program then when I EXIT the playback of the recorded program, the live TV now has picture and sound.

Does this work for anyone else?

Samsung TV no longer connects as Anynet+. Per the comments in this thread I've tried multiple HDMI cables, powering Xfinity box off, resetting Xfinity box completely, using a HDMI cable that works correctly with Roku. Nothing has worked. The Roku works flawlessly with the TV. The only thing I can do at this time is go to a HDMI source on my Samsung. The Anynet+ is no longer recognized. Is this an Xfinity box issue? I've had the box for 4 years. Now my Samsung TV no longer recognizes the Xfinity box as a Anynet+ device. It is no longer available even after I have rerun the 'Setup'.

@user_b520ba​ Have you made any changes to your TV settings or perhaps your cable TV box during all this troubleshooting? If your TV is is not connecting to Anynet+, that is a TV setting. Did you change an HDMI setting in the cable box?

We are having the same issue with our Samsung Frame TV.  We checked HDMI ports and cords, rebooted, etc.  We have literally done everything. We have a Switch connected with no issues so this is 1000% an Xfinity issue.  Judging by the responses and age of this thread, no one at Xfinity is working on an actual

fix at this point.

@user_e68ab5​ What devices are connected to the HDMI ports on your TV? Have any settings changed on the cable box or TV for HDMI? Added any new devices to the TV or rearranged HDMI devices? Did the firmware get updated? Something changed for this problem to appear. Have to narrow it down.

We only have a Switch and our Xfinity box connected.  It is 10000% an issue with the Xfinity box.  We’ve tested the HDMI ports as well as the cords and nothing else has an issue connecting.  Judging by the number of responses here, it’s an Xfinity issue and their SW/HW engineering teams need to push out an actual fix.

We've been having the same problem starting about 6 months ago. After a power outage the TV would display pictures just fine but ZERO sound. We replaced the cable box and had the same problems. Through some magic of powering on and off and swapping cables and ports it started working. Then the problem happened again within a few days. We replaced the cable box once again. In troublshooting I noticed that if you go to the xfinity button, devices, video, there is an icon that shows what kind of TV the xfinity box sees. If it says Samsung TV everything works, when it says unrecognized you either get perfect picture and NO sound, or a 640x480 size picture with sound. We were told that our TV was old and the ports were bad. We bought a new TV a month ago. Brand new samsung. It worked fine for a month. My wife shut the TV off to go to bed. I came back in and turned it on again, NO sound, same problem all over again. Resetting the xfinity box by unplugging power, or using the Xfinity my account app on iphone to restart the box fixes it most of the time. THERE IS A PROBLEM with the Xfinify boxes.

i have an older samsung smart tv and i had comcast listed as one of the available sources. i added a roku stream bar and roku was listed as one of the available sources. i was just using the xfinity voice remote and the roku remote separately and decided i wanted to try to use the samsung remote as a universal remote. after going through the samsung setup process for the voice remote, comcast and roku sources were no longer available. now, the hdmi 1 source allows me to view comcast and the hdmi 3 for the roku. the samsung remote did recognize the sony blu-ray dvd player on the hdmi 2 source. i have a request in for samsung tech support on 3/10/22 and will provide update.

I am having the same issues with a new Samsung Smart TV I purchased in January of this year. The Xfinity box cuts off and on periodically during the day and will not cut back on unless I unplug and replug it. It takes a while to reconnect. I went to Xfinity and got a new box. The problem I am having now is that even though I scanned channels using the Air and cable settings it gives a message saying Antenna not found. I also can only get the HDMI cord to fit in The HDMI 1 port. The other port will not fit the cord properly. I cannot pair my xfinity remote. There are also some issues with the Samsung remote. I have looked at videos and used other resources provided by Xfinity with no success. This is the first time I have had such difficulties setting up a TV. At one point it said to check my cable connections even though they were all tight. I even changed out cables to see if that was the problem. I am at my wits end. As I can see from this forum I am not the only one having these issues. HELP!!!
