Wired Ethernet stopped working

[Blondie79]

My TV used to work on Ethernet. That has now stopped working. For some reason it won’t connect over Wi-Fi either. So  I’ve now changed Ethernet cable which works on other devices and I get the lights on the switch. But still getting an Ethernet is not connected message. I’ve deleted all Wi-Fi profiles. Under wired LAN it says connected. Any suggestions?
