The Philips X5-1 exhibits failures similar to other transducers…lens damage, strain relief damage, cable pulls, connector damage, premature electronic failures and, the ever-favorite, accidental trauma. For years, the primary mode of failure on almost all cardiac probes was a breakdown of the individual coax’s within the wiring harness due to the way echo studies are performed. Cable/wiring failures are still common on the X5-1, but all the technological advancements in this probe have presented new modes of failure, never seen before.
