A-1 Transducer and Wedge Assembly
Broken wires near the transducers should be obvious, but broken or cracked

mostly occur at the edge of the solder connection. A break can generally be

You cannot repair a broken transducer in the field. Return any touchscreen with a broken
transducer to Elo for repair or replacement.
