I cannot acces i-player or other internet services on my TV. I have checked the network setup and it is ok. I can stream music from a netorked hard drive and other devices, (X-box and PVR) which are connected to the network through the same power line adapter can get onto the internet ok. When I try the refresh internt content option on the settings menu I get an error <5006> and a message to contact Sony. Any idea what the problem is?
