HELP needed here Phantom2, 3 months old, have added iOSDMini, FPV Transmitter, & Zenmuse H3-3D, GoPro 3 all worked very well, thenadded longer landing legs.

Now on start-up I get one green flash from camera side LED'sfollowed by constant short bleeps and no lights, at first there was a burningsmell but that is not there anymore.

Working on the only thing that I had moved fitting long legwas the compass, so orded new v3 part 16. But this has NOT fixed the problem. Anyhelp with is would be very great full.

...Looks like it's burnt out.....

Have you ever had it crashed??
Try to find the signs of burning and tell us which part had burnt out.

Hello Ian,
After watching the video, it's recommended to contact the nearest support center to have a thorough check for the product.

To help isolate the problem it may be helpful to disconnect all the add ons and see if the basic Phantom has the issue.  Also, if you hook it up to the Vision Assistant do you get any indications?

Lastly, it may be a broken MCU.  Check out the same symptoms on this http://youtu.be/kTpKcuU3nPE
