Abused is such a strong word, I do confess to getting the cord hooked on
a doorknob two months ago, but I did not notice a single click until two
days ago, really out of nowhere (thought it was the song I was listening

The 20 degree angle I mentioned was meant to describe the direction of
the force I need to apply to make the channel go out, it's not quite
that bad. But if I were to try to perform the fix you just described
I'd be looking for a new mp3 player :)

It seems like the application of the force is just barely pushing the
headphone connection off of the left channel contact, but while the
player is stationary I have no problems. I bought an L-adapter for my
good headphones and made a little mod to the neoprene case which keeps
the headphone connection isolated, and this pretty much works but
there's nothing worse than getting into your music and losing a channel,
major buzzkill.

If there is no easy fix that doesn't require the soldering iron, (which
seems doubtful) I'll make sure to give the tech at the electronics
repair store a copy of your instructions.

Thanks for the help.
