Anyone with other suggestions? Prime has never loaded on my TV. Just goes back to the Smarthub. I have shut off and on, pushed the power button for 5, 25, and 30 seconds as listed in different posts, Reset the Smarthub, Looked for updates, the TV is not registered on Prime, as it has never been used for Prime, set DNS to 8888, unplugged TV for the night, plugged in, pushed power button, held power button, reset entire TV, tried to watch Prime through the internet app and cried a lot......
1. Switched off and on the TV unplugged etc
2. Done the same for router
3. Deleted samsung account and reinstalled
4. Deleted and reinstalled amazon prime
5. I have 150mbps speed.
6. All other apps working
What's the solution
I live in New Zealand and experiencing the same issues, I have tried all the suggestions here to no avail. Today I had an on line ‘chat’ with Samsung NZ and they said they had no knowledge of the issue, I forwarded them this link and was told US televisions have different software, I replied that whilst I appreciated this I was getting exactly the same issues with a notification of insufficient bandwidth. After a fruitless conversation where I reiterated all other television apps were working perfectly and I had also carried out a total reset, plus Prime Video is working perfectly on all other devises I surrendered as he could offer no further help. Frustrating!
OK so the below worked for me, my device wasnt registered so couldn't deregister it just had a Prime app screen saying wasnt connected to internet.
I went into samsung tv network settings and disconnected my wireless internet connection from my TV.
I then reconnected my internet back to TV and when I tried the Prime App it worked
I am in the US.
I have a Q8 Series (65). This morning I attempted to load Prime. Prime attempted to log on--quickly flashed and then would not respond to my attempts to reload. I reset the Smart Hub and reinstalled the Prime app. No change. The TV did not show as a device on my Prime account. So I disconnected my WIFI. Reconnected the WIFI. No change. I then turned the tv off for a few minutes. Once turned back on the Prime Video app responded and landed me on the sign in/register device screen.
very strange but it is working now.
I tried deauthorizing my device but it wasn't listed on my authorized devices anyway. I followed the tested and true 1st rule of troubleshooting... Unplug it and plug it back in after a minute. Then hold the power button down for about 20 seconds till it recycles. Amazon started up just fine after that.
