b) Check all 37 sockets at the LMX connector, ensuring that none are blocked with debris.
If so, clean out the debris, reconnect the cable and try powering the system again.

5) Replace the Cable

If you have a spare cable, replace the current cable. If the system does not power on
or if the LMX Sensor is not detected with either cable, please contact your GPR
supplier for further assistance.

6) Test the Cable

a) On the end of the cable that connects to the LMX Sensor, check that none of the 37 pins
are missing, bent, or recessed. Look at the pins on an angle to confirm they are all flush
with one another. If one is bent or recessed, gently bend the pin back straight and flush
with the other pins. Connect the cable to the LMX Sensor and try powering the LMX
system again.
b) Disconnect the end of the cable that connects to the back of the Display Unit.
