TV won't register on Smartthings

[userAFGXR7jni2]

My qled TV went "offline" from smartthings the other day, and it won't reconnect. So I removed the device from smartthings and attempted to re-add it. It hangs on "registering device" in the app, and the TV says registration cancelled. I've tried everything. All firmware is updated. Everything was hard restarted. Reset accounts and smartthings on the TV, and even full reset the TV itself. Also had removed and re-registered the device in my Samsung account. Nothing changes. Still hangs on registration. No idea where to go from here.

Yup, have the same problem. Uploaded feedback to Samsung via the SmartThings app, hopefully they can fix this. I would suggest you do the same.

The exact same thing happened to me, on/about 12/5/25. Similar date for you?

Same here. So frustrating. Everything has been working perfectly for YEARS.

I’m having this issue with my 65 inch Q70 and the iPhone version of the app. I got a washer and dryer that are compatible with smart things so I connected them. I hadn’t used the app in ages, and saw my TV was listed as offline. In hindsight I wish I had just left it alone, but I removed my TV thinking I could just add it back. I have tried deleting the app, resetting the app data, and factory resetting the tv. Nothing has worked so far. I took my girlfriend’s phone and made a new Smart Things account with her email, and it will not connect to her account either. I also gave feedback within the app.

Same exact issue on the 2020 Q60 TV

Gosh! Same thing happened to my years old frame tv 32inch 2020 model, it has been good until 5th Dec, firstly appeared offline, I tried the factory rest on tv and re add it on smartthings hub but always shows the registration cancelled message on the tv screen after keyin the correct pin. Please fix it ASAP!

Same story here. It was Saturday morning when I woke up to all of my TVs being offline. They're a mix of 2020 and 2021 models. I tried factory resetting, moving the router, changing the bands, and even running an Ethernet line to the TV to try to fix the issue.

I am experiencing this as well on my 2020 QN75Q90TAFXZA. Lost registration, and then keep trying to add but get "Registration Cancelled" and it refuses to add to SmartThings again. Tried factory reset and WiFi change.

What fixed it for me: Flash reset via physical buttons (not resetting via the menu). Hold the power button on the TV for 5 seconds, then hold the power button on the remote for 5 seconds. This will erase all your settings, so make sure to take note of them beforehand.

After this, you should be able to set up the TV via SmartThings. I link my Alexa account to SmartThings, and control it via my Echo device. I heard some people can tell it to turn off the TV, but not on. I set up custom routines for everything to not rely on the "smart" deciphering Alexa or the skills use. If your Alexa won't decipher what you're saying, try this:

Create a routine -> if voice event ("TV on," "turn the TV on," etc.) -> then Smart Home -> TV -> Select device -> Power on.
