S6 Portable Digital Color Doppler Ultrasound System
Service Manual
10.3.2.3 Motherboard
The computer Motherboard is the central control unit of the S6 system, any
faulty part or any faulty connection/contact will cause malfunction of the
whole system. Ensure that all the connections/contacts with power supply,
RAM, SATA connector, and etc. are good after servicing. Problems with
these connections/contacts will lead to startup failure, auto shutdown, no
video output, and/or other system malfunctions.
CPU ventilation fan is an easily worn out part, ensure that the paddels are
rotating smoothly while the system is operating.
10.3.2.4 Ultrasound unit
Ultrasound unit (consists of DBTR board, DBF board and DBHV board)
takes most duties concerning signal processing and sequence control. Good
connections between these boards inside the ultrasound unit should be
guaranteed. Among the connections from the Ultrasound unit to other
units/parts, the following two are the most critical.
(1) USB2.0 Connection:
Ultrasound unit connects to Motherboard through USB2.0 port on the DBF
board. This connection is critical for the normal operation of the system. A
bad connection will cause the system to crash, auto shutdown and/or other
serious system failures.
(2) Power Supply Connection
All the power consumed by the Ultrasound module is transferred through
P3 and P4 (or P1 and P2 in some models) both on the DBHV board (7500-
0822-XX). The current flowing through these connectors, therefore, are
quite large. Bad connection increases the node resistance and reduces the
voltage supplied to the Ultrasound unit, or even worse, it will cause the
connector to burn. To avoid these problems, observe these precautions:
1) Hold the connector not the cable when disconnecting. 2) Ensure good
contacts at P3 and P4 (or P1 and P2 in some models).
10.4 Common Problems and Service Instructions
Note: If the system is locked up and requires a password to continue at
startup, type the password (press Shift key to change alphabet case) and
press Enter key (not SET key!), then restart the system. The password,
provided by SonoScape, consists of alphabets and numbers, and is case
sensitive.
