Repaired screen and now iPod won't play

Question

I replaced the broken LCD screen in my son's 1st gen black nano. It looks beautiful! There is a problem with the ipod now though. The iPod won't play. Everything works perfectly...screen is bright and beautiful, click wheel works to move through all menus, change volume, etc. You can choose a song, but the song won't play. The little triangle that stands for play is in the top left corner like it wants to play, but the status bar that tells you how long the song is doesn't move at all. You can fast forward through the song manually, but it won't play.
I have reset the ipod by toggling the hold button and pressing the select and menu choices from the click wheel. I have done the 5 R's that Apple suggests. I have even restored it to original facotry settings. iTunes can see it and re-downloaded all of the music onto it. All of the software on the computer is updated and the ipod software has been updated. Everything works fine except it won't play!
When I had the iPod open and was working on it, there were 2 ribbon cables that needed to be connected, 1 was the click wheel cable and 1 was the LCD screen cable. I have attached those securely and both are working properly except for the matter that it won't play songs. There was 1 other flat copper cable that seems to be glued to the click wheel that I didn't see in any of the pictures in the repair manual. It's not a ribbon cable. One end is still glued to the click wheel, but the other end is loose. This is probably the problem. I don't remember disconnecting this during the repair, although I know it had to be connected somewhere. I reaches up close to where the earphone jack is. Does anyone have any idea where this flat copper cable is supposed to be connected? I would appreciate any help you can give me! Thanks!

Answer 1

Here is the URL for the picture of the copper cable. The dark part at the end of the copper cable is a piece of silver metal mesh that is glued on one side of the copper cable. You can see that it is glued at the other end to the back of the click wheel underneath where the battery was glued down. I vaguely remember that it was connected to something else, but I don't remember disconnecting it because I was so intent on getting the ribbon cables disconnected without damaging them.
