I own a Sony 930 amp which i have been very happy with for the past two years. But recently I have noticed that when I first switch on the amp, i get a muffled distorted sound that is bleeding from the front channel into the rear right channel ! This is particularly prevalent when i have it switched to 5.1 mode that receives signals from my widescreen Panasonic (three years old) although it is still noticeable when i switch it to my DVD or satellite. The strange thing is- after a while - all is well and the amp works beautifully. Has any one else experienced this? I'm wondering if there is a loose connection somewhere inside - but i dare not open the box cos i'll probably take the whole thing apart and do more damage than good! Have a good Easter all !
