Hi @Jeremy501 Do you have the latest firmware? Sometimes Netflix can be the issue and so as @xSteveuk says try reinstalling it. As a matter of interest were any 3rd party apps installed as that can sometimes cause problems? Have you tried both the Smart Hub and Factory Reset. You could also switch off at the mains for 5 minutes.
If this messages still keeps popping up seems major issue and you would be advised to contact Av specialists on 0333 000 0333 as they will be able to run you through the options. See contact options here https://www.samsung.com/uk/support/contact/
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
