There could be a short. Check the board for any stray blobs of solder or other things that could cause a short. If you could draw us a picture on paint it could help us figure it out.

Your soldering looks ok, I would scratch in between the two pins on the right and clean that up a bit, I don' t think thats the problem though. Check your batteries to see if they are charged, and check to see if your Genesis is getting power by using a multimeter. If it is and it still won't light up, give the 7805 power directly. Like this.

Just plug in the battery and see if it lights up.
