I have a KD-43xe8004 43inch version which I bought last November (2017).
When I turned on the tv this morning everything was ok. I went downstairs and come back 30 minutes later and when I unmuted the HD channel I was on, suddenly there is this strange interference sound happening.
I can still hear the channel audio underneath the strange sound. If I change to the non-HD version the interference goes. The interference sound is on all HD channels.
I was thinking it might be something to do with youview? Because when I was searching about hd sound problems youview kept coming up in the searches.
How do I search when youview was last updated?
Is there a way I can turn youview off temporary or is it built in to the tv?
