No camera display on Android phone or tablet.

Everything was working fine around 2017, then I got a msg one day on startup saying update required, after update camera was not displaying video.

It would still fly.
I was packing to move to Arkansas so didn’t fuss with it.

It has never been crashed.

Now Oct 2019 I pulled it out of closet and on start up it said update required again to 1.11.20
Relinked RC to copter. Both manual and with software.

still no video.

Things I’ve tried
Format ssd card and attempt to update again
IMU calibration
Gimbal calibration
no damage found on gimbal ribbon cable.
Tried many different USB cables and phone and tablet.

It flys OK
camera is taking pics as I can put ssd in pc to view pics

Any help would be appreciated.

Make sure you do a clean new install , anyway i would use Plane Mode in each fly , just to avoid unwanted processes running below ...

Hope it help

Hi Coldheartid, I'm sorry to read your post. If the issue remains after multiple troubleshooting, I'm afraid that you may start a case and send it in for diagnosis: https://www.dji.com/service/repair thanks!

Just asking :

Does the P3 respond to commands from GO app ? Example - can you tap the Take-off tab and it rises ? Do you have all the telemetry data displayed such as voltage ... flight mode (P-GPS, ATTI etc) ... battery % line ... ?

When you say you take pictures - is the by pressing button on Controller or tapping tab on GO display ?

What I am basically asking - do you have control via GO and only video display not showing ... or is GO not functioning ?

When you fly in this condition - can you fly further than 50m from take-off point ? If you can - then it means GO is active. If you cannot fly outside 50m horizontally - then GO is not active.... as you see with this video I made to illustrate this (sadly I paid a high price for doing this as I could not gauge distance relative to the tree !).

I may have found the problem, here is part of the log file from the hidden file MISC.

Module 1500 and 0800 is not detected in some of the lines.

Using  https://phantompilots.com/threads/fix-no-video-feed-black-screen-no-image-transmission-no-fpv-on-ph3-pro.133487/#lg=_xfUid-1-1572461220&slide=0

and

https://github.com/o-gs/dji-firmware-tools/wiki/DJI-Firmwares

to analyze the log I see Video and USB communication as the likely issue.

So it looks like it could all be centered around the overheating of the DaVinci Chip during the firmware upgrade.

I'm a retired electronics engineer and this may be beyond my abilities.

I have a few more steps to check wiring and other connections before looking for a repair company.

You cannot store the Phantom 3 away for a long time without using it, I did this and the video feed circuit became corrupted, I had to send to Holland for repair from the U.K, it cost £200.
Reboot your Phantom and connect with the App at least once every month even if you're not going to take it out and fly it.
