The shorted DC in/sound card may have cause damage or component failure on the logic board. No real way to test it except to swap out the logic board. A new logic board for your Powerbook is not only going to cost $$$ but it's also difficult to replace.

Make sure you check all connections in and around where you replaced the DC in/sound card. It's possible something is loose or not making contact. Look closely at the small molex type connectors as they sometimes can lift up and lose contact with the board.

Regards.
