I have discovered a fix that worked for me, problem was Amazon prime would not load and could not reinstall..........
Unplugged TV for around 30 seconds, plugged it back in, switched on, and then went to app settings and attempted a reinstall. It then allowed me to reinstall and Amazon prime now works as expected.
Hope that helps someone...........
I am getting the same error, TV model code UE49RU7300KXXU. Apple TV stopped working. Unplugging for 15s didn't help the issue and when I attempt to reinstall Apple TV I get error code 125059.
I am facing the same issue with amazon prime , I tried
1. Restarting TV - that didnt work
2. Reinstalling the app - which I cannot do as it says "Error: Unable to install. Please try again later: (Amazon Prime Video: 125059)
3. Tried resetting smart hub and then re-installing the app - same issue
