Error code E-4044

Image artefact / channel failure

Error code E-4044 indicates an image artefact with channel failure. Streaks, dark dead zones or fixed artefacts appear in the live image because individual receive channels no longer deliver clean signals. The fault clearly sits in the beamformer and the probe path. That is exactly where we start, repairing at component level instead of replacing the whole system.

E-4044

What the message means

Streaks, dead zones or artefacts appear in the ultrasound image as individual channels fail.

Typical symptoms

This is how you recognise the fault in operation.

  • Vertical streaks or fixed dark bands in the live image
  • Dead zones where no ultrasound signal arrives
  • Artefacts that persist regardless of the connected probe
  • Image quality degrades gradually or fails suddenly

Possible causes

This is what experience shows is behind it.

  • Faulty beamformer channels on the receive board
  • Crystal defect or delamination in the probe head
  • Cold solder joints or contact faults at the probe connector
  • Damaged probe cable with a broken conductor

How we proceed

Diagnosis

We first determine whether the fault sits in the probe or the system by cross-testing with a reference probe. We then measure the beamformer path channel by channel and locate the failed channels on the board. So before any repair, it is clear which component is the root cause.

Repair

We restore faulty beamformer channels at component level in an electrostatically protected environment, instead of swapping the entire board. If the fault is in the probe, we recoat or repair the probe head to clinical standard. Every repair is documented with a test report and comes with a warranty, usually within 1 to 2 working days.

Frequently asked questions about this error code

Both are possible. Streaks and dead zones are caused either by faulty beamformer channels in the system or by a crystal or cable defect in the probe. We isolate the cause with a reference probe before anything is replaced.

No. In most cases we restore the individual faulty channels at component level. That is considerably cheaper than a full module swap and is often the only available solution for older systems.
