Loose headphone connection replacement necessary?
I'm loosing one half of the audio signal from the headphone jack, I can jiggle the jack and get both channels, but not for long.
Can the headphone jack be tightened in the Ipod, or am I looking at replacement?
There is no way you can tighten the connection. Personally I would just go ahead and replace it. It is not a very difficult job and parts are readily available To open it up and replace the jack follow these instructions iPod 5th Generation (Video) Headphone Jack & Hold Switch Replacement Good Luck and let us know how it is progressing :)
