Crashed hard into a tree, camera got ripped off, props all broke, drone fell to the ground and motors would not stop turning. Ended up having to pull the battery and got the tops of my knuckles chopped off in the process! When powering up now I get the normal tone then constant red\yellow\green LEDs. Manual says it's doing power on and self diagnostic test, but it never completes. I'm fearing new system board is needed (not to mention camera and gimbal). The DJI Go app just says Not Connected. Systemboard doesn't seem too hard to replace after taking the top off. Anyone got any thoughts or advice on difficultly level and where's the best place to get a system board? I see them new for almost $300 and on eBay for around $70. Thanks, Mitchell.
