Does not start up after battery and hold switch is replaced?

I purchased this iPod knowing that the battery was bad. After about a month of usage I finally decided to purchase a new battery. When I got it in I followed the detailed instructions on replacement. As I was detaching my old battery I had noticed that it had been leaking and damaged my hold switch ribbon. So I ordered a new one of those too. As I was putting it all back together and plugged my data/charging cable to it nothing happened. Not a start up screen nothing. I did try to reboot, went back in and rechecked all connections and still nothing. Is it possible my logic board was damaged? It was working before I took it all apart. Only as long as it was plugged in. Please HELP! (As Im beating my head)
