Make your measurements on the pin of the lmd not the circuit land.
A few things to check. Is either of the outputs presenting a steady state voltage that is near you power supply voltage or 0 volts or do you measure some odd voltage?
Do you have 5V at pin 14?
If you had access to a scope I would suggest checking pin 3 to see if your getting some indication the timing circuits working.
What is the voltage on Pin 9 of the LMD?
