The no image transmission with a P3P is historically one of the most common issues with P3Ps.
Over the years, we've routinely directed people to the flow chart put together by @quaddamage

Thanks a lot for responding and sharing the links to the schematics and the troubleshooting chart. I will look at the logs on the SD Card and see if there is any module showing the message "device not found".

Thanks a lot for responding and sharing the links to the schematics and the troubleshooting chart. I will look at the logs on the SD Card and see if there is any module showing the message "device not found".

Ok, there was no log in the SD Card, so I copied a very old Firmware, the version 1.1.8, and turned on the Aircraft. After about 15 minutes I turned off the aircraft and then copied the content of the SD Card on my Laptop. There was one log in the root of the SD Card and one under ./MISC/LOG.
I'm attaching both here, but however, I don't see any "device not found" or any error in the any of the modules.
Could somebody please have a look at these files and tell me if there is anything that I should do?

Hi All,
Is anybody willing to have a look at these files and tell me if there is anything that I should do?

Thanks in advance!

Here are the files

I've watched this video and it seems the problem might be caused by the fact that the Drone had not been turned on for a few months.

Thread 'Fixing flash in DM365 chip within Ph3 Pro gimbal'

Dec 3, 2017

Here is a success story I wanted to share.

I had a Phantom 3 Pro gimbal which didn't allowed me to see the FPV feed. Photos and movies were recorded on sd-card, there was just no live video - only grey background - in Dji Go.

I explained the details, and the road to fixing the issue, here:

@Oso @captainmilehigh
I just ordered Part 49, or the OEM Ribbon Cable, I went through the chart sent by Oso, and I tried with a different controller and still no luck on the consistent video feed.
I believe this might be the solution, although I am waiting to open up the main body of the drone until I get the parts. I have tried all other solutions recommended so far, so I assume this might be my problem area.

Thanks a lot for the chart, that is very well put together and was nice to follow.
