All of you guys..been in my position:

It can be intimidating in the electronic world. Roll up your sleeves and dig in - best way to learn is to get your hands dirty and figure it out. Take your time and think about the way the pieces come apart and fit together. The internet and service manuals are a great place to get information too - this website is KILLER in finding information and so many helpful people and threads here!

People have often asked me how I learned to work on cars - I basically just dug in and figured it out. Yes, it can be intimidating and you will make mistakes, but the more you do it, the easier it becomes and the more enjoyable it is! Good luck!!!
