I have had years of trouble-free performance from my NN3D MFD12, which I purchased as soon as they became available. I have immediately updated software whenever an update has been made available and am running the latest version now.
However, during my current long cruise, on two occasions when in chart mode, the MFD12 has suddenly displayed a fully pink screen. On the first occasion, I also had my DRS-4D radar on and in overlay mode and I received a message “radar connection cut” briefly, immediately before the entire screen went pink. It stayed that way for several minutes while I tried to figure out what had happened but I was then able to power off the MFD using its own power button, then re-start and all seemed normal. I continued cruising without problems for another week, then this time, no radar operating, the screen again went fully pink for about 15sec, but this time the MFD re-booted itself and appeared to operate normally for the next 4 hours until I shut down.
I am still away on our 6 week cruise and it has been fine for the 24 hours since this second episode, with radar variously on and off. The MFD had been on for about an hour at the time of the first incident; and for only 20minutes at the time of the 2nd event. In the earlier weeks of my cruise, there were 10 hour days when the NN3D system was fully up and being actively used continuously, without problem.
The MFD is supported by 320B and 330B gps units (the latter on the DRS-4D’s CanBus network and in backup/failsafe mode); a Furuno/Airmar DT-800 transducer provides depth and seawater temps; an ETR6/10 network sounder (not operating at the time of the pink screen incidents); and DSC & AIS inputs are received from Standard Horizon VHFs. The MFD12 is well-protected inside the lower helm of my motor yacht; it outputs to a Furuno MU-15 display at the upper helm (also well protected) via the DVI connector. I have no reason to think power supply was anything other than stable at the time of each incident.
Of course when I get back I could just pull the unit and ship it off to the local Furuno dealer for inspection….but I am guessing I am not the first to experience this pink-screen effect and I am hoping that you might be able to advise the most likely cause(s) of this?
Thanks in advance.
