ive had my pioneer 435 fde from JL for the past week and it constantly buzzes. i have read previous threads to change the pure cinema setting to off from advanced. this reduces the buzzing but it is still there. its can be heard all the time when watching tv or dvd. ive read that some people have exhanged their sets and still have got the buzzing. its definately not a fan sound ive attached the magnetic collar pionner supply to fit around the power cable to reduce noice. it sounds like a hive of bees are living in the back of the screen. does anyone have a non buzzing pioneer? or do i just have a faulty batch? shall i get JL to give me another one?
