Hoping that someone maybe abe to provide me with some help!!! I have just (6 days ago) bought a 37PF9975 from Currys. On the second day of having it, I noticed a buzzing sound. The sound/pitch varies when switching channels, between adverts, between black screens and pictures, when moving across text pages, etc.. Master care have been round to lock at it and I was told that that this is due to the RF 'cogs' and that they were aware that customers had been raising this as an issue but this is not a fault and the buzzing is acceptable!!! I have very very little knowledge of Plasmas but having paid 2k for the TV, I would not expect there to be a buzzing noise.. Does any one else have this model and are they getting this noise!! Or are Mastercare/currys taking me for a ride!! Any advise wouldbe very much appreciated.
