Bought TV new in Jan '15 and everything about it has been great until a couple of weeks ago. Now Netflix will randomly stop working and only comes back with a full TV factory reset. Sometimes it will work throughout a day then need a reset to work the following day. Sometimes you only need to come out of Netflix for a moment and it will not work if you go back in minutes later.

It will always come back for a full TV factory reset but that's an absolute pain.

The TV is networked to our BT Home Hub via wi-fi and Youtube etc still works OK so I assume the wi-fi is OK.

We have a Youview PVR connected to the TV via the same home hub and Netflix works fine on this playing to the TV via HDMI... but that's not the point as it's a feature of the TV we want to work without additional equipment.

The TV has the latest firmware.

My problem seems different to most Netflix issues on this site as the usual complaint is it just doesn't work at all. Any thoughts appreciated.
