The Problem has just developed for no reason whatsoever after several months of flawless use, my wing has never crashed or failed in any way until this morning. I arrived on site and upon sw my multi on I noticed the LED was not coming on at all. I rechecked all my connections and tried plugging the LED into the other available socket but to no avail any ideas?

I did a quick hover in Alti mode which seemed fine however without knowing the GPS status and adding to the fact I intended to recalibrate the imi/gps as I had changed my setup slightly after my last outing meant I was not going to risk my very expensive setup inc a Goodman Gimble / hoverfly combo.

I did contact the dealer I bought the WK from but said it would have to be returned to DJI for inspection (China) which could take a month or even more. He carried no spare LEDs and could not promise he could even try the LED out for me to see if it was a simple replacement needed which would save me the hassle of a full strip out! So if they receive the LED and its ok I then have to send the whole setup its nuts!

Is this normal of DJI? shipping back to them for a check over seems a bit daft why even have UK dealers if you get no help in sorting problems when they arise.

I wish I had bought a cheap naza now and at least I could have just bought a replacement IMU for £172 and kept flying. Paying £750 leaves you with a flightless multi for a month at least it seems and maybe even longer :(

Thanks in advance Colin

That happened to me too, three times now. Switching power off/on usually helps and brings the LED back to normal. One time I didn't notice the missing LED strobes and I flew; Atti was ok, GPS/Atti didn't work (although GPS did work beforehand).

My conclusion: In my case it seems to be a boot/power-up problem rather than a LED failure.

Hi hover.ch,
I am having problems with the LED on my Naza, it's also a BEC though, and sometimes it goes out completely (usually when the battery drops to about 3.9V/cell).
Did you solve your problem? what was the cause?

Thanks,
Dimitris

the Naza is a totally different setup to the wookong which components are routed through a BUS type system so sorry I can help, however it turned out my LED had failed and it looks like a common problem as some guy in the stated had sold over 60 on eBay. Mine was eventually replaced and all is now fine apart from a niggling slight rotation on my Y6

Thanks for your input Pinballer. My suspicion is also of some fault with the LED (maybe bad solder joint?), at least it's not a very expensive part to replace & dissect the old one!
