I have had Sony Bravia TVs for years, I still own 3 larger HD TVs. I bought this as a replacement for my kitchen recently and it’s been nothing but bother. It constantly loses channels so needs to be retuned, and then it won’t pick up some of the basic channels. I have never had this problem before but then I have never had a Sony Bravia with an ‘Android TV’ label on it.

Any thoughts what is wrong and what I can do please?
