Serviio

My tv has stopped "seeing" serviio, evey other device in the house can see it and connect to it.

as far as I am aware, nothing has changed, the server does not appear in the list of service to choose from, anyone any ideas; used to be that when it didn't appear in the list an uplugging would be enough for it to reappear, now nothing.

Since other devices are seeing Serviio, the problem is not there. The first thing to check is the network connection for the TV, making sure it's correctly connected to your network. But whatever the problem is, it's with the TV itself.
