Fading LED Characters on Navman Instruments

[FEIERABEND]

The characters on my Navman wind instrument tend to fade out or be incomplete. Not consistently but intermittent and with no pattern that I have been able to create and therefore replicate the problem. I have checked the voltage at the instrument connections and it is consistent with the only other on the same power feed. Any thoughts please? Thanks

My boat came with a navman wind instrument. I don't remember the model off hand though. When I first got it the characters would work/not work intermittently. I did research and found that it's likely humidity that was causing my problem. Since then the LCD's completely quit. While annoying, I use NMEA and can display the windspeed on my autopilot.

That said, see if humidity is causing any issues. Back when the issue started, I noticed there would be condensation in the faceplate at certain times.

Sadly you are a victim of Navman's poor quality control. The problem is caused by moisture inside the casing and there is nothing you can do about it. Any Navman instrument left outside uncovered will collect mositure. Sometimes just a tadge and you'll see the face fog up but I've seen them with water actually sloshing around inside the casing.

Navman's marine instrument division was bought out and is now called Northstar. Whether NS is any better than NM I have no idea.

The Navman quality problems are a real shame cos it was basically good, well priced gear let down by the aforementioned QC.

Thanks folks for your thoughts. I think that I'll give NS a shout and ask them if they can address the moisture problem.
