TV turns on randomly on its’ own

Check the settings on your tv. The boxes do a reboot in the middle of the night, its possible your tv is going into a standby mode instead of powering off and when the box resets it may be kicking the tv out of standby mode.

Yep! Connected a new Samsung TV to my downstairs box and it comes on randomly! Never did it before until I upgraded TV and box

Our Solution
Using our Xfinity XR11 remote we are now only turning off our Samsung TV/Xfinity system by only using the "TOP RIGHT POWER BUTTON" on the Xfinity remote. My husband is left handed, so he was using the top left button "TV" button, when turning off our Samsung TV/Xfinity system. Over the last month of only using the top right power button, the TV has NOT turned back on.

We found out that Comcast has a remote XR15 that should solve the problem, as it only has 1 power button on the top right. I will keep you updated once we receive the XR15 remotes and use them.

We are having a similar issue. Our Samsung is over 5 years old, and we are an Xfinity X1 customer. Over the last 6 weeks our TV randomly turns back on. The time varies. One common issue, is it has happened after a recording ended a few times. (1) We make sure the last show watched is live, and not behind or paused. TV still turns on. (2) We turned off the Comcast Labs feature "Smart Resume for Recordings". TV still turns on. We have reset our DVR multiple times. No settings have been changed in my Samsung TV, and I even turned off auto software updates. Please post if you determine what is causing this! Thank you.

My husband is left handed, so he was using the top left button "TV" button, when turning off our Samsung TV/Xfinity system. Cross your fingers, as for the last 3 weeks of only using the power button, the TV has NOT turned back on. This could be the solution for us!!! I'll keep you updated.
 
FYI, If you read my other posts you'll see we tried many other solutions, including removing the batteries from the Xfinity remote... that seemed to work sometimes, but the TV started turning back on, even with the remote batteries removed.

See my previous post... Q2.
Could this be an internet connection issue? If my dual band modem gets a poor signal or goes out while recording, could that cause the DVR to turn on TV to get to the cloud, to download or upload the scheduled recording? Thank you.

Update 1, Turning off the Anytime+ CEC function in my TV... DID NOT WORK.

5/19/19 Update 2, Xfinity advised to remove batteries from remotes, as remote could be defective. Still testing this.

Ok, I found and turned off the Anytime+ CEC function in my TV settings. My TV is over 5 years old, Samsung TV LED65 7100 series, and my DVD is about 1 to 2 years old. And, this has never happened before. I hope this works, without losing functionality of my TV! I'll keep you posted. Thanks.
Updates above.

Update 1. Turning off Anytime+ CEC function in my Samsung TV settings did NOT work... as we came home after being away 2 hours, and our TV was on. Nothing recorded while we were gone. Cannot find any cause. Any other suggestions?? (Refer to my prior 3 posts for more details.) Thanks.

take the batteries out of both (all ) tv remotes (and cable remote). might be a stuck button.

Greetings, peg4! I appreciate you taking the time to reach out to us here on the forums. I hope you are having an amazing day. I apologize to hear you are having the issues with the TV randomly turning on. Looks like you have been working with Rustyben on the issue. I was just wanting to follow up to see if removing the batteries from the remotes have fixed the issue. If it has not, feel free to send me a PM with your first and last name so I can look further into this.

It has been 3 days since we removed the remote batteries, and our Samsung TV has not turned on again, on its own. We are waiting for the new remote to arrive. I'll update you if the problem recurs, once we begin using the new remote. Thank you for your help.

This had happened 3 times this month. I too have a Samsung

UPDATE 6/21/19
TV started turning on again by itself after using new remote about 10 days. Removing batteries from remote at night, to see if TV still turns on. So far after 10 days of removing batteries, the TV has not turned on.

Will update later.

See update above...
Great news! Since we received the new remote, the TV has not turned on by itself. So it looks like the old remote was defective, and causing the TV to turn on.

If anyone is having this problem, I suggest you take the batteries out of your remote, when your TV is off, for a few days to see if your TV turns on by itself.

FYI, We noticed the new batteries we put in the old remote ran down in just a few days, possibly due to a stuck button or internal damage, making the remote send a signal that turned on our Samsung TV.
