My Macbook pro, 2.33ghz generation, is plauged with that buzzing sound that occurs when the laptop is at less than full brightness. According to various internet threads, the display inverter is faulty and apple acknowledges the problem, and recommends sending it into apple care. However, my laptop is out of warranty and I don't want to both pay apple money sending it in and be without it for a week just to fix a minor annoyance, so I was wondering if any one had any success at replacing the Macbook Pro display inverter. I am looking at buying this, and trying it myself- http://www.yallstore.com/laptop-replacement-lcd-inverter-for-apple-macbook-pro-15-p-2881.html is this something worth trying? has anyone had any success with this?
