Opened up my mavic pro due to a gps #2 disconnected message.. after seeing the condition of the gps module, I ordered a new one and buttoned her all back up... Waiting for the GPS part to be sent in to install..
But now I have a camera sensor error and no video shows.. just a black screen.. no other errors... Gimbel has full movement and passes the gimbel sensor calbration test 100%.... Ony cables I took apart was the 3 black ribbon flex cables to front while taking out the main board....
Any ideas?

It looks like you also managed to accidentally butcher the solder connections on the fixed end of the flight control board connector....... looks like an easy enough fix to sweat it back on...

Where do you see that? The last photo of that white wire is the coming from the gps module that I am waiting to come in to swap out ..

The marks on the GPS patch antenna are quite normal. They used to use cadmium to protect the antenna surface from corrosion. It is a sacrificial coating. Cadmium is a health hazard and I believe they have replaced it with a safer soft metal.

That said it could still have failed.

My issue with it was I didn't see the DJI logo on it like all the other photos I have seen... And the white wire was in bad shape....
Even though it says compass #2 disconnected I was told it could be the main board as the one up front seemed fine.. all wires intact and solder connections looked good....

But now when I put it back together I get no video and cera sensor error

I could be the core board. The GPS modules communicate by simple TTL level serial data, which would be read by a serial port on one of the aircraft’s microcontrollers. That wiring does look very dodgy though.

Other than damaged cables or a power fault to the camera board it’s hard to say what’s causing your latest issue.

Sorry to hear that. Hopefully it’ll be a quick fix and not too expensive.

Wtf
Hell no
I just replaced that GPS with a brand new unit so that's definitely not the problem the arm I could care less about
Yikes! I wonder if they’ll actually fix it or give you a used replacement. If they guarantee it will be fixed it may be worth it in the long run.

Spare parts will always add up to more than the initial purchase price. And then there’s labour on top.

Just a horrible experience they already fixed all the parts without consulting with me first on if I wanted to go ahead and go with the charges..
All I wanted fixed was compass number two and the camera sensor..
They ended up replacing the GPS module the arm and they said they replaced the front vision sensors.. that was a mistake on the part of them coding their billing wrong..
After me arguing with the manager that's what he dropped it down to.
Sheesh
