Troubleshooting
System Troubleshooting
This section describes troubleshooting procedures which can be used in conjunction with or
separately from the diagnostics to isolate a failure.
Caution:
When troubleshooting, partial disassembly may be required. Ensure that the external
power supply and rechargeable battery(s) are disconnected. When disassembling the
monitor, use a nonconductive shield to insulate the main PCBA from the front bezel
assembly (a piece of cardboard will suffice).
Display Troubleshooting
No Display or Touchscreen Response
1 Make sure the external AC to DC power supply is properly connected (the green light on the
monitor front panel should be lighted). If the green light is OFF, troubleshoot the external power
supply.
2 Cycle the front panel power ON/OFF switch several times, and verify that a tone is produced
each time the switch is depressed. If no tone is produced, carefully pry the button cover from
the front bezel assembly and verify that the button movement is free of contaminants. Try
pressing the button without the button cover installed. If this does not resolve the problem,
continue to step 3.
3 Remove the plug-in patient parameter module. Cycle the power switch to obtain a tone. If no
tone is obtained, sequentially remove each of the following assemblies, cycle power and check
for a tone before removing the next assembly.
• The Plug-in optional recorder assembly and its CPU PCBA.
• The IO bay option panel.
If the tone returns after removing one of these assemblies, repair or replace that assembly. If
the tone is still not produced, go to step 4.
If The Monitor Produces a Power-ON Tone But No Display is Present:
4 Observe the LED that is below the bottom center of the display; this LED can be seen through
a small viewing hole. Also the LED will shine onto the surface that the monitor is placed on.
5 If the LED is not flashing during boot up and there is no display, then the main PCBA or the front
bezel is defective.
