Hello,
I purchased a crashed mavic pro as a bit of a project for days when I couldn't use my working MP.
Tested it on 2 fully charged batteries and I get the same result with both:
Switch on, you can hear it trying to start up, motors do that little twist they do.
It goes quiet right when you would normally get the gimbal doing its thing.
Then it starts beeping, a single beep, 2 second pause, single beep, and so on till I turn it off. The sound is coming from all 4 arms. A search suggests this is the ESCs? If it makes a difference I can notice there is noticeably more vibration in the front right and rear left motors (motors with the white lines). There is also a faint buzzing which appears to be coming from one of the sensors on the bottom, when I put my finger over this it muffles the sound so I'm convinced this is the source.
I've tried pairing it with the remote from my other MP but it won't work (assuming I'm doing it correctly), the controller goes in to "Binding" then times out.
I've tried connecting it to the wifi through my android LG G5 and I can't find the SSID.
Tried connecting to my windows 10 PC and DJI assist 2. The PC recognises the device but suggests there is an issue with it. DJI assist 2 does not change from the "connect a device" home screen - I've had issues connecting my working MP so this does not overly concern me in itself.
Summary of damage:
Gimbal was damaged and slightly bent back on itself. It was sticky going side to side and total frozen in the vertical axis. Knowing this is most likely dead I used a little gentle persuasion and I've freed this off. Still no movement when drone is powered on.
The small tab on one side of the rear arms has snapped off - therefore you can bend the arm slightly past what should be it's maximum travel - I'd imagine this has no impact on the non-starting issues.
The bottom metal case is dented and the plastic casing was popped off at the side.
I've opened it up to check for any obvious physical damage, or loose connectors etc. Whilst the actual fan appeared to be intact, its plastic shroud for bolting it down etc was broke in to several pieces and had damaged the grill.
Everything else appears to be intact and to the untrained eye in usable condition.
What I did notice it that it looks like someone else had opened it up - there was a single screw missing in the battery tray.
Current thoughts:
Previous owner has crashed it and bricked it.
Previous owner has crashed it, opened it up to repair/replace the fan and/or gimbal and touched something they shouldn't have.
Is the damaged gimbal is preventing the device starting up.
Is the damaged fan preventing the device starting up.
Has the fan stopped, causing the device to overheat and that's why it crashed.
Is the potentially faulty sensor causing an issue.
After some more searching this evening I realised that it has an internal SD card containing the software (assuming it is an older build), I did notice there was a finger print on the cover of this (could well be my own), so tomorrows plan is to remove this SD card and inspect it.
Thinking the worst and that it is totally bricked.
Any and all help is appreciated.
Regards,
Grant
