toshiba 36 zp

does anyone out there have a problem with the tosh 36zp and buzzing
when you are watching the tv a irratating buzzing noise comes from the inside of the tv and the speakers this changes in loudness quite a lot and is starting to get to me
has any one got the best settings for this tv to get rid of this problem or is it a fault that should be dealt with by the dealer
i have purchased good cables (qed) at 30 quid a pop x 3 so dont think it is them
i have tried all the basics like swapping cables ,re tuning etc and i still get this buzzing . not as bad when watching tv through the outside arial but as soon as i switch to sky this buzzing increases
any thoughts
cheers nidge

I had this with my first 36ZP. It didn't do it 100% of the time, but did it more often than not. After a week I called the store and got it replaced. No buzzing on the replacment.

I must say probably the most impressive thing about my PF2 is just how damn quiet it is. I'd call for a replacement if i were you.

Its a known possible fault with the power supply, which buzzes when a lot of power is required on some modes. My tv is silent.

cheers everyone i will ring me supplyer and see what they say
