How to fix Furuno FAR-1513 Marine Radar picture not updating?
If the picture on your Furuno Marine Radar is not updating or is frozen, it could be due to the bearing signal generator board (in the antenna unit), the SPU board, or a video freeze-up. Check the connection of signal cables. Replace the SPU board. Turn the radar off, then on.
What to do if Furuno FAR-1513 power is on but nothing appears on monitor?
If the power is on but nothing appears on the monitor of your Furuno Marine Radar, the brilliance may be too low. Adjust the brilliance.
What to do if range changed, but Furuno FAR-1513 Marine Radar picture does not change?
If the range on your Furuno Marine Radar is changed but the picture isn't updating, try adjusting the range using the control unit or the [RANGE] box several times. If this doesn't work, power cycle the radar to resolve potential video freeze-up. If the issue persists, the keypad may need to be replaced.
Why Furuno FAR-1513 picture orientation is incorrect?
If the picture orientation on your Furuno Marine Radar is incorrect, it could be due to the terminal board (RFTB/ RTB inside the transceiver unit or FRP_TB board inside the processor unit) or the SPU board. If the message “HEADLINE” appears in orange letters inside the alert box, the heading signal is lost or interrupted. Check the heading line signal cable and terminal board connections. If there is no problem with cables or connections, replace the SPU board.
Why Furuno Marine Radar picture is not updated with each sweep?
If the picture on your Furuno Marine Radar is not updating with each sweep, it could be due to slots in the rotating disc in the antenna unit or the motor brushes. Remove any foreign material (carbon, grease, etc.) from the slots. If the motor brushes are shorter than 6 - 7 mm, replace them.
Why Furuno FAR-1513 Marine Radar has poor sensitivity when tuned properly?
If your Furuno Marine Radar is properly tuned but has poor sensitivity, possible causes include a deteriorated magnetron, a detuned MIC, dirt on the radiator face, water ingress to the waveguide or other feeder line, or the second trace echo rejection being ON. With the radar transmitting on 48 nm range, check the magnetron current and replace if below normal. Check the MIC detecting current and tune if necessary. Clean the radiator surface, remove water from the feeder line, and disable the second-trace echo rejector.
Why Furuno Marine Radar shows marks and noise but no echo and no transmission leak?
If marks, indications, and noise appear on your Furuno Marine Radar but there is no echo, and the transmission leak representing your own ship's position is absent, it could be due to several reasons. The TX high voltage protection circuit may have activated (reset power to restore normal operation), the magnetron may be faulty (check magnetron current and replace if necessary), the modulator board may need replacement, or the SPU board may be the issue (replace SPU board).
What to do if Furuno FAR-1513 brilliance adjusted but no picture?
If the brilliance is adjusted on your Furuno Marine Radar but there is no picture, the issue may be with the SPU board. Replace the SPU board.
How to fix Furuno FAR-1513 Marine Radar antenna not rotating?
If the antenna on your Furuno Marine Radar is not rotating, it could be due to the antenna drive mechanism or a defective antenna drive motor relay. To fix this, replace the antenna drive mechanism or press the relay reset button.
How to fix Furuno FAR-1513 Marine Radar when range changed but picture not changing?
If the range is changed on the Furuno Marine Radar but the picture is not changing, it could be due to a defective range key, a faulty SPU board, or a video freeze-up. Try adjusting the range with the control unit or the [RANGE] box several times; if that doesn't work, the keypad may need replacement. If still not working, replace the SPU board. Alternatively, try turning the radar off and on.
