    My 60gb 5th generation iPod Classic has been going strong since 2006. I've replaced the battery a couple of times, but other than that, no issues. This week, all of a sudden the left channel stopped working (you can only hear sound through the right earbud). I've tried different headphones, and it has the same issue, so I know it's a problem with the iPod itself. I ordered a replacement headphone jack, which I have since received and installed, but the issue is still present. Does this mean the problem is caused by the logic board? What's my best course of action? Thanks

    Make sure the ribbon cable is inserted and secured. Also, if u have a speaker dock or cable, see if it does the same.

    Do you mean the ribbon cable connecting the headphone jack to the logic board? Yes, it is secure. It demonstrated the same issue with two different headphone jacks/cables, too.

    I don't have the means to check the audio from the dock. Is the audio from the 30-pin connect analog or digital?

    I did notice there appears to be a small burned/brown spot on the foam that insulates the hard drive from the logic board. Based on placement, this would have been caused by the two components just below where the headphone jack ribbon cable connects to the logic board. Is this the D/A chip or amplifier?

    Ok, long story, but I got another logic board (Logic board X) from another 5th gen iPod 60gb, put it in mine, and everything worked great. But then I accidentally broke off the battery connector as I was putting it all back together. Got my friend to go back to my bad logic board (I'll call this Logic Board Y. It still had battery connector attached, just one burned component right below the headphone ribbon cable attachment - probably the cause of the dead left channel), take off the burned component, and replace it with the one from logic board X (the one that I broke the battery connector off). Then I install logic board Y into the ipod. This is my original logic board, just with a new component replacing the burned one. For some reason the ipod would now not turn on, so I considered logic board Y to be dead.

    So, I got him to put that component back on logic board X (the new one, which now has a missing battery donnector), and then de-solder the battery connector from Y and solder it to X. Now the iPod turns on, but it's the RIGHT channel that doesn't work. It was the left channel before, so this isn't making any sense to me. Essentially i'm using a new logic board, but one of the components has been removed and re-attached, and it has the battery connector from the other logic board. Any ideas?
