45 minutes - 2 hours
I take my iPod to bed - and on a certain day the headphone jack got twisted - and damaged my iPod internally. So: no more music. It was a very very sad day. The most economic way to fix this was to order the required spare parts and tools and do it myself. (If others can do it, I can do it too)
Repair went fine but I took my time: about an hour. I Read the instructions thoroughly.
Removing the cover without damaging/bending it was the hardest part. I did not use the plastic opening tools - they were no real help.
Take your time and concentrate. Remove tape over cables slow and gently. Watch carefully that the flat cables remain flat - I had a small problem with that. The new cable was bent next to the headphone jack and this resulted in a very distorted sound.
At that point I thought : "My GOD, what have I done!?".
Gently straightening the cable solved the issue and my iPod was as new. Then I taped the cables back on their original places.
Tip 1: order the required tools.
Tip 2: Test your iPod while it is still open, if anything went wrong - you can easily look for the problem without the need to reopen the thing.
Tip 3: keep cats, spouses and children away from the operation quarter.
Couldn't have done it without iFixit though, big thanks guys!
