Philips Medical recently released the successors to the extremely popular iU22 and iE33 ultrasound/echocardiography systems. The new flagships are the Epiq 5 and Epiq 7 premium ultrasound and echocardiography systems.
As with any new product release from any manufacturer, there are service challenges which may include software and hardware design issues as well as malfunctions. The design issues are why we always recommend customers ensure their systems are at the latest hardware and software revisions prior to expiring warranties and if problems continue, to remain with the OEM until the product stabilizes. If products are unstable, it may be difficult to determine whether a service event is a malfunction or related to design problems.
Let’s take a brief look at troubleshooting common power problems on the Epiq. Starting with the main power button, there are four states:
1. Off – no power applied to the system
2. White steady – system is in standby/5V DC standby present
3. Green steady – system on
4. Green blinking – system is in standby
If the system does not power on using the main console switch, there may be a problem with the user interface. You can bypass this by pressing the momentary switch on the backplane located just below and left of the board barcode. If the system fires, you likely have a bad control panel, audio input output (AIO) or cables. There is a USB cable from the AIO to the control panel you can disconnect for troubleshooting purposes.
Troubleshooting the ATX power supply module is simplified by LED indicators for the 12V, 5V, 3.3V, -12V and 5V standby. Note: The -12V is not generated by the main power supply. There are also LEDs on the main power supply which provide status of:
1. LED 1 above main AC input – On is AC present
The following LEDs are from right to left beside the power supply ground lug starting with number 2
2. Battery status
a. Off – AC absent, battery not enabled
b. Yellow/green blinking – battery calibration ongoing
c. Steady yellow — battery charge low
d. Yellow blinking – battery fault
e. Green blinking – battery partially charged and available
f. Green steady – battery fully charged and available
These are just a few basic troubleshooting tips for these new systems. For greater detail, please register for our Epiq Troubleshooting Session on TechNation’s Webinar Wednesdays. The session is on November 18 at 2 p.m. EST and registration is available at: www.1TechNation.com/webinars
