I know nothing about electronics, but I want to fix my computer speakers. They were expensive and the warranty has run out. The problem with them is they just don't turn on. I opened them up, and checked all the soldering and it was still intact, but I noticed that the board everything is soldered to was cracked in half. It's not completely separated but there is a fracture line running accross the width of the board. Is there any way I can fix it without buying new parts? Like can I use solder to connect the little foil pieces on the bottom that are separated by the crack? Is the foil(actually I don't know what it is) on the bottom surface off the board, or is it embedded? Thanks.
