Question Buzzing noise from Sony STR-DN840 transformer ?

[Matthew Smothers]

I have a Sony STR-DN840 and when it is on for two or more hours the transformer starts to make a LOUD buzzing noise, not a hum, a BUZZ, is there anything I can do to make it not buzz so loud, or do I need to find a replacement part? and if I need a replacement, can anyone send me a link?

record a video with the buzzing sound and upload to e.g. youtube or similar
might be a normal sound for such a transformer

Buzzing noise from Sony STR-DN840 transformer ?

 

[helpstar]

that´s coil wining I think, could get better by replacing the transformer

so what coil, where is it, do I need to replace the coil? or transformer

 

[helpstar]

the transformer is a big "coil", so replacing it could help

Hey thanks for the help, me and my dad where able to reduce the noise by adding rubber grommets on the transformer screw
