Thunderbolt Display Power Supply Buzzing

Texto:

Think it may be a transformer, caps look ok. Happens most when under load (magsafe and Thunderbolt connected to Mac) but buzzing will start if display is left plugged in overnight.[br]

Anyone else experienced this?[br]
 
I am hoping to repair instead of replace the power supply.

"you can fix that by changing the suppression capacitor its a 0,22 uf marked as a 22k275v x2 mine was a carli orange i changed it by one with wires the store told me it is beter to prevent buzzing in belgium it only costs 0,75 cent a lot less than a new psu"
 
I changed the cap and everything seems good so far! :)
