Hi las3r,
Here I just got done posting some pics on exactly that.

What are you wanting to put this board in? What LED or LEDs are you using?

I think this is something you can do your self. I am well aware of the feeling you get when your electronics get 
ed. I have had that experience more than I care to admit, but these drivers are very cheap and once you have done it a time or two they are simple yet very effective and powerful circuits.
I really think you can do this, and we've all got your back. If you need help trouble shooting you can post pics.

is there away to test the driver without being in a flashlight ?
if so i have this DMM http://www.hobby-hour.com/electronics/3320multimeter.php

Dont be discouraged this is only a minor set back.
The most common reason for this stuff not to work is a short. Its very easy to get an accidental connection. You can use your DMM to check for this. Switch to the continuity setting ( the one that makes noise when you touch the leads together if you didnt already know
) A common place for these boards to short is where the LED- wire attaches to the main board. If that wire is touching one of the other legs of a 7135 chip besides the right leg of the one is it suppose to that will = no light. Or if that same wire is touching the outer gold rim = same thing. Another common place is also where the LED + wire connects, if that touches the outer rim of the board = no light.
If all those check out touch one of your DMM leads to one of the connections going to the slave and then touch the other lead to each of the other 2 slave wires. You should not have continuity touching any combination of the 3 wires.
We could more easily help if you had a picture of the actual drivers that you worked on.
If you want to do your work outside of the light ( I do mine that way often) just stick another LED to a good solid chunk of metal for a heat sink and hook up the driver to that with a battery etc on the table, this makes trouble shooting much easier.
If by chance you dont find a short, I would disconnect the slave and hook up the main board only and see if the board is working.
