Phantom 3 Professional , Need high dev. picture of mainboard a broken mainboard ( Identify SMT ) .. :)

[gianasisters-c-64]

Hello there

I have a Phantom 3 Professional. She currently does not start because I had a nice landing in the water
I do forensic data recovery for water damaged devices and was able to replace every defective part except one.
Would you please help me with a high definition picture of your main board to identify this part ?
The only way you could read the number on this part with a USB microscope would be to wet it a little with
a Qtip and shortly before it is dry again, you can ready the numbers and letters on it. I believe mine starts with a number 2 .... ( Marked in Yellow )
Looks like a DIP , maybe a voltage regulator..... ? Every other part is working well
If you could identify the part or maybe have a defective board that I can take this part from that would be awesome !!!

If you could help me that would be awesome

Thank you much !
Kind regards
Frank

"200"?

In v7 board it had 3 legs, and there was no coil nearby.
So I think it was a linear regulator in v7, and was switched to buck converter in v9.

Yep, I have a #33 board and it definitely is marked 200.
I have a extra board if you want it.

Hello Team I received the Board from KachemakDiver ? ❤❤❤

Many many many thanks !!!!

I used a Hotair station to remove the failed component marked "200" from the defective Board that he send me. I noticed that he solder they use is quiet stronger than "normal" solder. What I mean is that it does not flow using the normal temperatures for SMT rework on similar electronics.

A temperature of 423 Degrees for about 10 seconds with an Airflow of 1 out of 8 on a pre heated board finally released the component. The reason for the low airflow was the other close contact SMT Parts and me being out of Kapton Tape .

Do yourself a favor and mark one leg of the component being removed. It turns out they don`t like heat very much and any markings on the chip like the number"200" on my part was totally gone... ?. Believe me , no microscope is going to help you.. lol
Anyways. The removal process form the Board that KachemakDiver has send me is now done.
I am going to get some Kapton Tape and some alcohol to clean my own board and then I am going to place the chip from KachemakDivers Board on to my Board. It`s been an easy journey so far ...

As you can see there happened to be a nice explosion , and yes that is the remainder of the Qtip and solvent that I used. LOL ( I am in my improvised Lab at the moment )

If GOD let me live another day then I will update tomorrow

WOW, that chip was messed up. Hope the board cleans up so as to be successful with installing the replacement chip?

That`s going to be fun lol about 1 am here.... I will update tomorrow.I am reading myself into the problem with your board right now... Have a good night (morning ) lol

Thanks, you have a good night sleep also ?

Gooood Morning !

The Soldering Job went well and the GPS started working.
Now whenever I try to take off it gives me the dreaded ESC Error.
I will investigate tonight ! (pictures will be posted ! )
If we can find out the reason for that we could make a lot of people happy
I am assuming a Mosfet or the IC that controls the voltage going to the mosfet.....
Since it took a quick dive in the water I am wondering if a shorted Motor ( or wrong resistance in the motor could cause the ESC Error ) ... I am going component level now and I will identify the logic behind the chipset to see if I can find a in that I have to put "high or low" to give the "OK" for takeoff.,,, lol I hope that made sense
( I did upgrade the firmware for the Remote control and Drone no avail )

Kind regards
Frank

I had ESC error on all my Phantom 3 projects, downgraded firmware to P3X_FW_V01.09.00600 and got them going.
