I recently took delivery of the Sony KV36HQ100S. I have only had the Tele for about a month and its started to make a buzzing noise from the back of the unit. Normally I can't notice as I have it loud but late at night when my wife has gone to bed the volume is much lower it is then I have noticed this buzzing noise. It makes the noise whether the tele is muted or not and I have tried DVD a Cable box and normal terestial it makes no difference. Do I need to call Empire-Direct and get someone to look at it or is there a fix I can do at home? Your help is going to be invaluable.
