replaced headphone jack and hold switch but now it won't turn on?

I ordered the ipod video headphone jack / hold switch and swapped it out following the instructions on this site but once I get everything reinstalled the ipod won't turn back on?? has anyone else had this happen? I reinserted all the wire strips multiple times but nothing seems to work. any advise would be helpful.
