Zusammenfassung:A method and an electronic circuit are disclosed. The method includes detecting at least one operating parameter in an electronic circuit that includes a monitored LED string; adjusting a voltage threshold based on the at least one detected operating parameter; detecting a string voltage across the monitored LED string; comparing the string voltage with the voltage threshold; and detecting a defect in the LED string based on the comparing.
