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?
