My Phantom 3 pro sat for some time , i decided to fire it up again. but i cannot get it to connect to the app. I checked the USB board and its ok, i tried it with Litchi and dji go but no luck. Aslo turned off debugging on tabley/phone. Tried several new connecting usb cables. Tried resetting controller . All i can do is get it to bind to the drone, and it will turn on motors and control the drone. But the app says disconnected.
It does not indicate that it needs a firmware update. Not sure what steps i can do to get the app running and get the camera working ?

Are you getting anything thru the app? I've read that if it sets for a while, the camera/gimble boards will get cold solider cracks and not display video from the camera.

Mine has the same issue, no video. But I do get data with the app. I can also record video and take photos to the SD card.

Had you previously updated the firmware?
im not sure if i updated it a while back, but is there a way i can down grade to an earlier version and see what happens.
it appears the controller just will not connect to app.

Most likely bad solder joints on the USB port of the controller. Sometimes you can identify this by wiggling the cable under the controller.

In this video you can see how to remove the USB-board from the controller:

I believe had same issue before on one of my P3Ps, downgraded to this bin phantom 3 0090 FIX bin.rar use a fan if you decide to downgrade.

Be VERY careful with installing firmwares.
Some firmware versions can NOT be downgradded.
Some firmware versions are for the controller only, some for the drone only and most (the All in One firmwares) for both the AC and RC. Inconsistent versions between the AC and RC will also cause problems.

At least read the 'Release Notes' for your P3P.

You can download it here:

DO NOT DO ANYTHING WITH THE FIRMWARE!!!
The very fact that the drone and RC are talking to each other rules out firmware issues. You can fly like that if you want, you just won't see what the drone sees.
I had this issue with my P3A and the culprit was ribbon cable from the USB input on the RC to the mother board. There was also a dry joint where the USB socket was soldered onto the USB board.
