Bravia 43xf8096bu will not tune Freeview HD channels any more

[TonySpath]

I came back from a month away to find my TV had evidently had some software change done to it. I am now unable to tune any HD channels that were there before (BBC1,2,4 ITV, Ch4, Ch5). It only has SD channels. The HD channels are on the mux from the Aerial - I know because I have a Sony Bravia in another room that still picks up those channels from the same aerial. I have tried retuning, retuning with the aerial unplugged, removing the aerial before all the channels are loaded on a retune, powered down, crash powered down mid retune - all to try and reset what I suspect is the existing and seemingly un-rewritable memory buffer containing the SD only channels. I am reluctant to try a factory reset as I have a complicated setup and it will take me an hour or so to put all the settings back again. What do you suggest?

Hi Tony,

Welcome to the Sony Community.

Have you tried a soft reset (Power Reset)? If this does not help then a Data Reset would be the other alternative.

It might be worth getting in touch with the Sony Support team here who will be best to advise further.

Best wishes,

Sean
