As your strip needs a program controlling, so one of the reason can be the code, check that if you have downloaded the code successfully. You can use the led connected with digital pin13 for the test or use the sample code BLINK.
If you can download the code well, check the power supply, it need 3.3V to 5V but no more than 6V as recommend, and the power also must be able to supply enough current for 1A/m,that means what you have bought from DFRobot is 1M and your power need to supply 1A for the strip, never forget when connect the wire ensure the voltage. If too high voltage has supplied, may good luck be with you because I used to supply more than 6V for a short while but nothing happen.
OK, no problem with the code or the power, now you need to check whether the led is broken. Unpin the signal pin with Arduino, but let the power supply connect as usual. You need to use a jumper cable like https://www.dfrobot.com/index.php?route=product/product&filter_name=cable&page=2&product_id=130#.Ur2OT7I5uTU to connect the Arduino pin to the second signal point in the strip which means use the jumper cable to connect the Arduino and the strip but not in the origin way for maybe the first led of your strip is broken. For this way, check the third or the fifteenth until the strip shine again.Then cut the broken led off and use the new point for signal point, this step you may need to solder the cable or use a clamp to connect the line.
