Hi, a week or so ago I purchased a Philips 32PF9976. Generally pleased with it with a few exceptions. Firstly, when watching sky and then turn over to say terrestrial BBC1 you can hear, oh so quietly the Sky vocabulary running in the back ground. Any suggestions what that could be, is this just a faulty scart? Secondly, if watching a TV program the sound is fine, then an advert comes on which has a bit of bass, there is vibration coming from the back of the TV ~ can anyone advise what the optimum sound settings are for this particular model? or suggest what this could be ? Finally, Ive noticed the set generally gives out a low pitch hum, which I can hear more and more as the days go by. Probably cause it annoying me more than anything. No one else in the family have noticed it. Any advice would be appreciated, before I go back to where I bought it from.
