The embodiments of the invention provide an electronic circuit with an LED module. An electronic circuit and a method are disclosed. The electronic circuit includes an LED circuit, wherein the LED circuit (1) includes: an input (11, 12) configured to receive an input voltage (VIN); a drive circuit (2A) connected to the input (11, 12); and an LED module (3A) connected to the drive circuit (2A) andcomprising an LED string (41) with at least one LED. The drive circuit (2A) is configured to monitor the LED module (3A) for the occurrence of an LED short in the LED string (41) and to change from anormal mode to a defect mode upon detection of the LED short, and the drive circuit (2A) is configured, in the defect mode, to operate the LED string (41) in at least one defect cycle that includes deactivating the LED string (41) for a deactivation period, activating the LED string for an activation period, and checking for the persistence of the LED short in the activation period. 本公开的实施例涉及具有LED模块的电子电路。公开了一种电子电路和方法。该电子电路
