Clean the board with 90% isopropyl alcohol and a toothbrush. Try to get the shields off, if you can then just brush what you can. Replace the battery and bring it to a electronics repair place that can get the shields off if you can't. After the board is all clean put it back in and try to fire it up. If it doesn't, send it somewhere. If it does, test everything and make sure it works.
