1. A method performed by test circuitry for testing flex cable shielding of a consumer electronic device comprising:
- applying a signal across a first portion of the flex cable shielding and a second portion of the flex cable shielding, the first and second portions of the flex cable shielding on opposite sides of a flex cable;
detecting a parameter associated with the signal; and
determining whether a break exists in the flex cable shielding based at least partially on the detected parameter.
