Replacement of damaged LCD Screen
The LCD screen was only useful on the right half. The left half was damaged. I went to the Apple store and they had no stock to repair and would replace with a similar computer for $1200. After two other web stores were out of stock with little hope of getting new stock in, I bought a replacement LCD screen for my powerbook pro from iFixit.
The replacement took 2-3 hours. It went slowly because of the delicate nature of many parts. The reassembly was much faster than disassembly. The directions on the iFixit web site were clear but had to be read carefully. When turned back on the familiar apple startup screen came up immediately proving the screen was functional.
Separate screws as you go. I used 5 containers that held the screws in the order of removal. Do the work in a location were the very small screws can be easily found if dropped. Read directions carefully and go slowly.
