The present invention provides an apparatus for detecting the abnormal soldering of an electrostatic discharge protection chip, comprising a connector, which is used for pluggable connection with a signal input terminal connector of an application specific integrated circuit chip (ASIC) of a liquid crystal display; a detecting circuit, which is set on the connector, used to detect if the electrostatic discharge protection chip is properly soldered on the ASIC and prompt when the abnormal soldering of the electrostatic discharge protection chip is detected. Accordingly, the present invention also provides a method for detecting the abnormal soldering of an electrostatic discharge protection chip. According to the present invention, the abnormal soldering of an electrostatic discharge protection chip can be detected quickly with high accuracy, which can save the cost of manpower and resources, as well as to reduce the loss resulted from the defective rate of the finished product assembly.
