I just finished building my Alpha Clock Five White kit, and it powered on fine and displayed Hello World. A few minutes later it shut off, and I couldn't get it working again. Then it came on again. Now it sometimes works, sometimes not. Not sure if it's a bad solder joint or bad component somewhere.
Are there any troubleshooting tips? Or areas to check for proper voltage or operation? Or should I refer to the schematic and figure it out myself?
Thanks,
Daniel
