<p>Did you solder a 1.2k ohm resistor in series with the SMLED? Also I looked at the board instructions and didnt see anything about it, but did you flip it over and look for a trace shorting around the built in resistor? I have no idea if these boards need a trace cut or not, and I dont have a picture of the backside of one or the rating of the LED resistors. Contacting TCS as others have suggested may be of some help. </p>
