Check the transformer to be sure it is generating 24 volts to start with. If the transformer is not defective and generating 24 volts then start going down the low voltage device line till you find the device or wire splice that is defective or loose. This testing/tracking down system is used throughout the HVAC industry and if done properly will soon find your problem.
