Troubleshooting: Troubleshooting procedure
The video display has no power. Verify that the display's power indicator is illuminated.
The patient monitor has no power. Verify that the patient monitor's power indicator is illuminated.
The video display is not properly connected to the patient monitor. Verify that the correct cable
connects the video display to one of the 4 video ports on the patient monitor.
The display was turned off via the Display On/Off button on the keypad/remote control. Press the
Display On/Off button on the keypad/remote control.
Hardware failure.
1. The SDRAM test performed by Boot Code failed.Check the LS6 LED (I'm OK). If the SDRAM test
failed, it will continually flash error codes.
Error codes always start with 3 very short pulses in quick succession.
Binary 1s are long ON pulses.
Binary 0s are short ON pulses.
The first digit is the most significant.
There are 6 binary digits per error code.
A short pause occurs between the first 4 binary digits and the last 2 binary digits.
If you observe error codes, replace the processor pcb.
2. Boot Code not loaded properly or is corrupt. This may be the case if the I'm OK LED is stuck ON or
OFF. Replace the processor pcb.
3. Power supply failure. Replace the power supply.
4. Loose connections to power supply. Tighten connections.
5. Excessive loading on external connector due to malfunctioning peripheral device. Isolate and replace
the malfunctioning device.
6. Other. Replace the power supply.
7. Power supply replaced, but display still doesn't work. Replace processor pcb.
1. Check the boot banner for hardware test results. The following information is available:
SRAM test results (passed or failed)
SDRAM test results (passed or failed)
Main flash check (passed or failed)
Boot flash check (passed or failed)
Real time clock (is running or failed)
If any of the above is failed, then Boot Code refuses to run the Main Code. Cycle power on the patient
monitor and it may correct itself.
2. Attempt to start Main Code via the "return to Patient Monitoring". One of the following may be the
problem:
Main Code not loaded. Follow the software installation instructions to download Main Code.
(These instructions ship with the software upgrade kit.)
Main Code and Boot Code not compatible. Follow the software installation instructions to update
the Boot Code to a version compatible with the Main Code. (These instructions ship with the
software upgrade kit.)
3. If the problem is still not corrected, replace the processor pcb.
Check the connection between the video display and the patient monitor and correct, if necessary, or
replace the video display with a known good one. If the problem is not corrected, replace the processor
pcb.
