It is possible to fix yourself, but man is it an involved fix. Yes there are guides on ifixit, but be aware that the job takes awhile. Especially if you've never taken a machine apart before.
Just be careful, go slow, and keep track of every single screw labeling where they go.
I disassemble machines daily. I had to replace an inverter and a backlight once on a 2007 model. I NEVER want to do it again...
