same problem.. tree times!!!!
Hi Guys, I would like to give you my testimony about me having the same trouble with two different machines. One year ago I bought a windows based laptop and after using it for one month I had the disturbing noise coming out whenever I turned the screen illumination down. On the same time, the screen got very hot on his down-central part, where there is the logo. I sent it to the assistance and they sent it back after a week, writing they replaced something called "lcd inverter" but guess... the laptop wasn't working yet! same problem... the bad noise was still there. so I sent it back a second time and they changed the entire machine (replacing the HD of course). Yesterday my new mbp baby started to do the same problem, even though the noise was much less loud then on my PC, so I decided to bring it to the assistance today. This morning I asked the technician about this on my mbp and he said something should be wrong with the or logic board. In fact, I'm not so sure he was a technician though. Anyhow, basing on my personal experience, replacing the LCD inverter doesn't fix the problem but I really ain't go a clue about hardware so I guess you'll have an explanation for what happened....
BTW: the fix it for sure, the machine is under guarantee.
sadness ...
In my case (I live in Rome) they said it will take them at least 4 days to fix it, because they need to get the pieces sent from Holland. On my expereince it will take them up to ten days! Ciao
