Here is one very
quick video Here is some more
pictures and description As far as screws and parts etc. You'll have to take a lot of pictures, you'll need to sort out which screws go where and tag them individually and in groups with numbers on Pictures as to where the go. This is as with any disassembly of anything someone is not intimately familiar with.
Great care has to be taken with cable connections they are easily damaged. Really if your not confident that you can do this you shouldn't as you will be breaking your warranty
