E8 built-in speakers resonate/rattle
I've recently bought a 55" E8 and I'm delighted with the picture. However, I'm having some issues with the sound.
In terms of audio quality I've found the built-in speakers to be fine for general use, and reasonably good for films and drama. As I have quite a large lounge I have to have the volume over 50%, and when that happens I hear a distinctive 'rattle' or vibration from the TV. This is triggered by bass notes and even some bassy voices. I can't work out whether the rattle is coming from the speaker cabinet or elsewhere on the TV. I thought it might be from the casing at the back.
It's very annoying and I can't believe that this would be acceptable for a premium TV, so perhaps something is loose, or a speaker cone has blown? I've deselected all audio processing and under 'Standard' settings I've used the equaliser to roll off 100hz and 300hz to minus 10, but the rattle still occurs.
Does anyone else have the same issue? If not then it could be classed as a fault and I may return the TV under warranty. If you've managed to cure it I'd love to know how.
