The left-speaker (at least I think it's the speaker!) on my PD7200 is slowly on the way out. It started by emitting a buzzing noise with the low-frequencies were(MTV Base, Movies etc.) it had never done this before, but recently the symptons have got progressively worse in that the speaker doesn't come on straight away - the right one works fine, the left one will come on for a few moments, then drop out again. Is a call to Hitachi required here? or does it need to go back to the store?
