I have a KDL-43W807C TV which I purchased on 27th December 2015.

Over the last 3 months it's been rebooting itself regularly but other than an inconvenience I've just ignored that.

Yesterday it's stopped working entirely. When it turns on I get lots of "[service] has stopped working" error messages, e.g. "TV storage has stopped working". The TV then reboots. It's in a reboot cycle like that.

Can anyone help?!
