Ive not had this TV more than a week and ive noticed a Buzzing noise its at the left hand side of the TV i have the TV wall mounted to. At first it wasnt noticable you had to go round the back to heat hear it. I purchased the TV from an e shop and have the guarantee so what do i do now contact them or contact panasonic i registered the product online on sunday through the panasonic website. Im not to keen on a replacement as i might get the same problem a shame to because i like the TV a lot.
