Success in 40 minutes with no Experience
The left headphone was getting no audio.
Smooth. The only issue was the small clamp which held down the wiring to the side of the battery, it came off but went back on with a pair of tweezers without a fuss. Now I have extended the life of my 8 year old Ipod and learned some confidence with electronics!
Give it a try, you will come away with more than a fixed device when you are done!
