weird screen problem

[polishmacuser]

i got my macbook back from applecare to replace my screen and when i got my macbook everything was fine and dandy until i noticed whenever i dim the display it starts making a buzzing sound like if something were loose inside. I resetted the nvram and pram but that didnt work. So should i go to apple or what?

I'd say it's a broken screen inverter. Time to get take it back to Apple.
