23.3 Power up troubleshooting
Product does not turn on or keeps turning off
Possible causes Possible solutions
Blown fuse / tripped
breaker. 1. Check condition of relevant fuses and breakers and connections,
replace if necessary. (Refer to the
Technical Specification section of
your product’s installation instructions for fuse ratings.)
2. If fuse keeps blowing check for cable damage, broken connector pins
or incorrect wiring.
Poor / damaged /
insecure power supply
cable / connections 1. Check that the power cable connector is correctly orientated and fully
inserted into the display connector and locked in position.
2. Check the power supply cable and connectors for signs of damage or
corrosion, and replace if necessary.
3. With the display turned on, try flexing the power cable near to the
display connector to see if this causes the unit to restart or lose
power. Replace if necessary.
4. Check the vessel’s battery voltage and the condition of the battery
terminals and power supply cables, ensuring connections are secure,
clean and free from corrosion. Replace if necessary.
5. With the product under load, using a multi-meter, check for high
voltage drop across all connectors / fuses etc, and replace if
necessary.
Incorrect power
connection The power supply may be wired incorrectly, ensure the installation
instructions have been followed.
Product will not start up (restart loop)
Possible causes Possible solutions
Power supply and
connection See possible solutions from the table above, entitled ‘Product does not
turn on or keeps turning off’.
Software corruption 1. In the unlikely event that the product’s software has become
corrupted, try downloading and installing the latest software from the
Raymarine website.
2. On display products, as a last resort, attempt to perform a ‘Power
on Reset’. Be aware that this will delete all settings / presets and
user data (such as waypoints and tracks), and revert the unit back
to factory defaults.
Warning: Factory reset warning
Performing a factory reset will restore all system and app settings to factory
defaults and erase all user data (such as waypoints, routes, tracks, camera
recordings and photos).
Performing a power on reset — Axiom™
Important:
• Before performing a power on reset ensure you have backed up your settings and user data
(waypoints, routes and tracks) to a memory card.
• You may also want to save any crash logs that are stored on your MFD to memory card for
future reference..
1. Switch off power at the breaker to ensure that the MFD is completely powered off, and not in
Standby mode. Alternatively, remove the power cable from the display.
