Sony hd tv sound distortion on adverts

[SimonRiden]

Hi all.

On my new Sony HD tv, some adverts the sound distorts. Sounds really deep almost like it has been slowed down but in fact is at normal speed. Is this a TV problem or signal problem? Not really worried about missing the odd advert but am worried it could get worse.

Cheers Simon

Hi @SimonRiden   What is the full model number of your TV? It will start with KD, XR or K.

Hi there. I think it is KD43X75WLPU, but can check when I get home. I have a video but don't think I can paste it here
