I believe I'm running into the same issue as seen in a number of threads. Here's a sample: viewtopic.php?f=41&t=25358
I see the led lit. the lcd display is powering up and the contrast is changing according to the pot setting. I can see that there is a 5v power at the appropriate check, but it seems that the pin going to the buzzer isn't outputting anything.. i'm not sure if there are any additional troubleshooting steps you can point me to or if I need a new monochron processor.
Any assistance would be appreciated. It's my first kit in years, so be gentle! :)
