How to troubleshoot Raymarine a78 that won't start?
If your Raymarine Marine Equipment system or part of it does not start up, there could be a power supply problem. Check the relevant fuses and breakers. Also, verify that the power supply cable is in good condition and that all connections are tight and free from corrosion. Finally, ensure that the power source provides the correct voltage and sufficient current.
Why does my Raymarine Monitor not turn on or keep turning off?
Your Raymarine Monitor might not be turning on or keeps turning off due to several reasons: a blown fuse or tripped breaker (check and replace if necessary, and inspect for cable damage if fuses repeatedly blow), a poor or damaged power supply cable or connections (ensure the cable is fully inserted and locked, check for damage or corrosion, and flex the cable to check for reboots), incorrect power connection (ensure the installation instructions have been followed), or an insufficient power source (check the power supply voltage under load).
What to do if my Raymarine Monitor displays a “No Fix” GPS status icon?
If your Raymarine Monitor displays a 'No Fix' GPS status icon, it could be due to your geographic location or prevailing conditions preventing a satellite fix (check periodically in better conditions or another location), a GPS connection fault (ensure external GPS connections and cabling are correct), or an external GPS antenna in a poor position (ensure the GPS antenna has a clear view of the sky).
What to do if my Raymarine Monitor will not boot up (re-boot loop)?
If your Raymarine Monitor will not boot up, it could be due to the power supply and connection issues. Also, in the unlikely event that the product's software has become corrupted, please try re-flashing the latest software from the Raymarine website. On display products, as a last resort, you can try to perform a ‘Power on Reset’; however, this will delete all settings/presets and user data and revert the unit back to factory defaults.
How to fix weak Wi-Fi signal on Raymarine a78 Marine Equipment?
If you are experiencing a weak or intermittent Wi-Fi signal with your Raymarine Marine Equipment, temporarily disable each wireless device in turn until you have identified the device causing the interference.
Why is instrument data missing from some Raymarine Marine Equipment displays?
If instrument or other system data is missing from some but not all displays on your Raymarine Marine Equipment, check that all required equipment is connected to the network. Verify the status of the Raymarine network switch and ensure that SeaTalkhs/RayNet cables are free from damage. If a software mismatch between equipment is suspected, contact Raymarine technical support.
Why can't I control the thermal camera from my Raymarine a78?
If you cannot control the thermal camera from the Raymarine display or keyboard, ensure the thermal camera application is running on the multifunction display, as opposed to the video application which does not have camera controls.
Why isn't the touchscreen working on my Raymarine Marine Equipment?
If the touchscreen on your Raymarine Marine Equipment does not operate as expected, ensure that the touch lock is disabled. The touch lock can be turned off on the home screen using the Joystick. Also, make sure you are operating the screen with bare fingers, as gloves may prevent correct operation. Calibrate the touchscreen using the setup menus. If there are saltwater deposits on the screen, carefully clean and dry the screen according to the provided instructions.
Why is instrument data missing from all Raymarine a78 displays?
If instrument, engine, or other system data is unavailable at all displays on your Raymarine Marine Equipment, check the data bus (e.g., SeaTalkng) wiring and connections to ensure data is being received at the display. Verify the overall integrity of the data bus (e.g., SeaTalkng) wiring. Check the source of the missing data (e.g., ST70 instrument or engine interface) to ensure it is operating. Also, check the power to the SeaTalk bus. If a software mismatch between equipment is suspected, contact Raymarine technical support.
What causes Raymarine a78 Marine Equipment radar to not initialize?
If the radar on your Raymarine Marine Equipment will not initialize and the Voltage Control Module (VCM) is stuck in “sleep mode”, check the power connection at the VCM. Ensure the voltage at the input is 12/24V and the voltage at the output is 40V. The issue could be due to an intermittent or poor power connection.
