Hi Mac friends,
For the past several months, my MacBook Pro 15" has been exhibiting the display inverter buzzing issue. It's out of warranty with no Apple Care. After reading many posts on the subject, I was convinced that it was indeed the display inverter based on the following:
1. The buzzing is localized to the bottom front of the screen, just behind the MacBook Pro logo on the bezel.
2. The buzzing goes away when LCD brightness is at 0% or 100%
3. I am able to physically push on that area of the bezel and make the buzzing noise go away temporarily or change pitch/sound. I can also affect change in the buzzing by altering the orientation (angle) of the LCD panel.
With that, I ordered a new inverter from WeLoveMacs and replaced the old one. The buzzing is no better and no worse at this point. Any ideas on a possible secondary cause for the buzzing inverter? Any clue what exactly is happening, as in does the inverter actually vibrate? That is my theory based on the fact that I can alter or eliminate the buzz by pushing on the bezel. I'm trying to avoid sending this thing off to the depot to the tune of $400 and X weeks without it.
Thanks for any information or suggestions!
