Ultrasound Service — Level 2: Fault-Finding
From the symptom on the screen to the failed module: probe or system, transmit, receive, beamformer, power, PC
Part of the program: Ultrasound Service Engineer — full program (40 h) →
Level 1 taught you to test a probe. Level 2 starts when the probe is innocent. This course teaches the engineer to move a fault before touching a screwdriver, read the logs and built-in tests, and follow the symptom through the front end, the beamformer, the power chain and the PC to the one module that has failed - then prove the repair with a phantom and a safety test.
The probe was replaced. The stripe is still there.
- A dead system channel looks exactly like a dead probe, so clinics buy new probes and the stripe comes back.
- Boards and power supplies are swapped at random because nobody built a swap table or read the log first - and a shorted probe can kill a new supply the same way it killed the old one.
- After a repair the image looks fine, so the electrical safety test and the phantom comparison are skipped; that is where an unfastened earth lead or a weak transmit path goes back to the patient.

Curriculum
Separate a probe fault from a port fault and from a system fault with a fixed swap sequence, and map the symptom on the screen to the block most likely to have failed before opening a cover.free
22 min02Atlas of image artefacts: what is physics and what is a fault
Recognise the common ultrasound image artefacts, decide which are expected physics or settings and which point to a probe, system or interference fault, and choose the right next test for each.22 min03Probe fault diagnosis: elements, lens, cable, connector and testers
Locate a probe fault to the array, lens, cable or connector, read a probe tester report with its limits in mind, and decide between repair, replacement and removal from service.23 min04Mechanical 4D and TEE probes: motors, oil, encoders and insulation
Diagnose the typical failures of mechanical volume probes and transoesophageal probes - motor, oil and bubbles, position sensing, steering and insulation - and know which checks are yours and which belong to a repair facility.22 min05Transmit, receive and probe switching
Localise faults in the transmit high-voltage supply, the pulsers, the receive channels and the probe switching (relays and multiplexers), and handle transmit-power errors safely.23 min06Beamformer and signal processing: start-up errors, channel loss and Doppler faults
Diagnose start-up hardware-check errors, channel loss and mode-specific faults in the digital beamformer and processing, and separate a Doppler hardware fault from settings, licences and interference.22 min07Power supplies and cooling: won't start, shuts down, reboots
Find the cause of 'does not switch on', 'shuts down' and 'reboots under load' in the mains input, the power supply chain, the cooling or the load, using indicators, logs and safe measurements.23 min08PC, operating system, disk and software
Diagnose boot failures, freezes and software faults on the PC back end, restore a system from the manufacturer's installation media without losing options and presets, and stay within licence rules.22 min09Peripherals and integration: monitor, touch panel, printers, DICOM and network
Fault-find the monitor, touch panel, console controls and printers, and diagnose DICOM worklist and image transfer problems step by step together with the hospital IT and PACS teams.21 min10Verification after repair: proving the system is fit to return
Plan and perform the checks after an ultrasound repair - functional checks, all probes and modes, phantom against baseline, electrical safety per IEC 62353 - and write a repair report that justifies the return to service.22 min—Exam

FAQ
Is this manufacturer training?
No. It is independent, vendor-neutral training. It does not replace the manufacturer's service procedures, does not grant authorisation or access to service software or licences, and every repair must still be followed by the manufacturer's required calibrations and checks.
Do I need Level 1 first?
Level 1 is the prerequisite: probe inspection, air image, phantom baseline, electrical safety and documentation are assumed here and not repeated.
Does it teach repair at component level?
It teaches fault-finding to the module: probe, port, board, supply, PC part. Component-level repair of boards is covered in the Repair Fundamentals course on electronics and power supplies.
Will I work on live systems?
The course explains which measurements on live, open systems exist and why they are only for trained personnel following the manufacturer's documentation. It never asks you to bypass interlocks, licences or safety measures.
What does the certificate say?
Your name, the course, the hours, the date and your exam score, with a unique number and a public verification page.
Can my company buy seats for a team?
Yes: five seats and a progress overview for the manager.
