LED malfunction

Just finished my first board--rapsberry pi B, thermocouple pit, ambient sensor probe 3. Boots up fine, everything works minus the following:
1. LED's won't activate even after tinkering with the software settings to try and nudge them
2. Lid Open function doesn't seem to work--nothing happens when pit probe removed from my armpit (I know, this seems a little strange, but it's an easy way to calibrate the probe and also test it).
3. The buzzer doesn't sound off. I haven't set up any alarms yet, so maybe that's the cause?

Any help would be appreciated.
 
James, check to make sure the LED's are not reversed. That has happened. Did the LED's flicker at all when you first applied power?
With no alarms set I don't think the alarm will sound so you are probably right on that. Not sure about the lid open thing. Good luck.
