My powerbook had a broken and unreadable lcd screen. I bought a replacement screen on EBAY.
I had the basic tools needed for the repair. I needed a smaller torx screwdriver and tools to seperate the screen from the housing. The exact tools I needed were offered at the bottom of the IFIT repair guide page. After receiving the tools ( in only 2 days ! ) , I started the repair. I used the IFIXIT online guide, and the repair was explained well with many photos. Now I have a usable laptop again.
The only area of caution was with the the antenna board. When reassembling the unit it was very easy for the wires to become unattached from the posts. Also re-installing the protective cover was a pain. I ended up using scotch tape to help keep the cover in place. The rest of the repair went smoothly.
