Those PCB's are tempermental. There are many a reason for your problems.

1. There is too much solder on one connection
2. The switch wires may need to be switched on the PCB
3. There may be parts of the PCB that are bridging that you are unaware of.

I have gotten this to work, but I did need to do some troubleshooting...even after I had everything hooked up correctly. Good luck.
