    • Second component likely to fail is the TVS Diode (Transient-voltage-suppression diode). It is used to protect the sensitive circuit from overvoltage.

    • Measure the resistance on the two terminals. Resistance should be infinite.

    • If component is broken the circuit is shorted. Therefore the component can be removed in order to repair the device. Afterwards the circuit is not protected against overvoltage anymore!
