first of all, you need to check the attitude that comes across in your posts.
it makes me not want to help you, but i will anyway.
coming on to a forum asking for help, and then trying to tell everyone how unhelpful their assistance was, is just plain rude.
also that schematic is as easy to read as they get. im not sure how you are able to do the repair but not able to understand the schematic.
to me it seems like you didnt even try.
oh well, here is what you need to know:
from top to bottom, there are nine tabs you need to solder to.
1 will be the top, and 9 will be the bottom.
1. BLACK wire from MIC CORD
2. BLUE wire from MIC CORD
3. RED wire from MIC CORD
4. YELLOW wire from MIC CORD
5. BARE COPPER WIRE from MIC CORD (its the shield, and its wrapped around the white audio wire) and BLACK wire from circuit board. (not the wire coming from the battery, the one coming off of the PC board) both of these wires get soldered to the same tab.
6. BROWN wire from PC BOARD.
7. PURPLE wire from PC BOARD.
8. WHITE wire from MIC CORD.
9. WHITE wire from PC BOARD.
the black wire from the battery connector gets soldered to the PC board right where the BROWN wire connects to it.
the RED wire from the battery connector gets soldered to the tab of the volume pot that connects to a resistor with the colors Brown-Black-Blue on it.
thats about as simple as i can make it, oh, and i got it all from the schematic you said was useless.
good luck,
