For no image, weak channels, probe-port errors, or labels that mention TX, RX, RF, RFM, DRX, GRX or beamformer boards.
No image · channel dropout · probe interface error · RF / RFM / DRX / GRX / TX / RX / BF faults
Rongtao isolates channel, transmit, receive and RF faults on live ultrasound systems, then repairs and re-tests the board for 48 hours.
DBM64 — Digital beamformer (64-channel)
Image anomaly after warm-up (thermal-dependent failure)
Hardware init / configuration
Auto-reboot loop, reports hardware initialization and configuration failure
How to prepare a Front-end / RF repair inquiry
A clean inquiry lets Rongtao identify the board, quote faster and decide whether repair, replacement or sourcing is the best route.
What symptoms point to Front-end / RF problems?
No image · channel dropout · probe interface error · RF / RFM / DRX / GRX / TX / RX / BF faults
What photos should I send?
Send clear photos of both sides of the board, close-ups of every label, the connector area and any visible damage. Include the machine brand, model and error code or symptom.
Can Rongtao quote repair without the board in hand?
Rongtao can give an initial route from photos and symptoms, then confirms final repair scope after receiving and diagnosing the board.
