- Start with the theory that "less is more" when doing this procedure. You can always heat it up more, but it is difficult to un-melt it. :-)
Travel Photo Film has an excellent disassembly video. • FIXED! DJI Phantom 4 ... I did not see a video online of the actual reflow process, so here is mine.
As you can see, it took several tries. But in the end, it was a success. Note: Low setting @ 550 degrees for just over 1 minute.
Hot Air gun from Harbor Freight- $14. DJI repair quote- $200. New controller- $399. I like the $14 fix. Thanks to all who contributed information.
FOLLOWUP: I did a 20 minute safety/test flight following this procedure, to ensure that the re-assembly was solid. Testing all functions, controls, in various modes, at low altitude/close proximity. With that successful, I did a 1,000 foot distance flight. All good. Update log books, and we are good to go.
Thanx man! You just saved me nice amount of cash! My Phantom 4 pro+ didn't charge at all. Now works ething fine... Thanx
Thank you! It worked like a charm. The alluminum paper kind of melted a little mine heatgun body tough
I've done this four times, but even if reflowing seems to solve the charging problem, it occurs again next time I need to charge the controller. So, not a permanent solution for my controller. ☹
I’ve found this too. 5th time now.
Same
Same.
I had the same issue with mine. Had to repeat the process 3 times as well as reflow both the power and battery connectors on the 3rd attempted and it worked. Initially the control sticks where not working after I reassembled the remote so I brought the drone indoors and tried it again and they worked. I don't know why this happened but all good now. Great care should be taken when heating the board I guess.. Issue finally fixed, happy days!!!
Thanks.. Very nice guide. I have an issue after reflowing it.. Before doing so, i could connect the DJI Go 4 app to the drone. But now when i plug in my samsung it says "Check your charger connection." I have taken it back apart 2 more times to make sure everything is plugged in securely and it is.. But the app still wont connect. Any suggestions would be great.
thank you for your advice i did the same.
All OK.
This does work. I used a heat gun with a narrow tip and cover off the areas that I did not want to expose to the high heat. Thanks. At first I thought I had my volume turned down but then I realized that you just were not saying anything in this video. That is the beauty of video, you see pictures and hear sound too.
Thank you!! its works like a charm =)
I heated it using a regular heat gun and isolating the same area. First during less than 1 minute, more lights working... Second attempt for a minute and everything works.
seems to bes easy but I just Brooke my whole Controller and now I am struggling to buy a new Mainbord.
After the first try it worked only for a day or two, than I repeted the process and it works fine since that.
Thanks!
Big thanks helped and everything works. Once again, thanks a lot. For me it worked at 400 degrees and one minute of heating
I did that already l, but the red light is been beeping. Do you know is another fix for that
which IC should change or IC Number
You`re right. Why the fuck noone said that the IC should be replaced rather than reflowed.
How do I know if it is actually working and charging, is it when all 4 lights start to go from left to right? I heated up the board a bit and it has 1 light blinking like what happens at 2:11 in the video and it just keeps blinking. Does that means it’s good and is charging? Or do I have to heat it up in other places as well
I can see my real charge when I turn the RC on while pressing C1, C2 and the Shutter button ( it's the silver button on the right side). But when it turns on the main LED is white and I can't connect to my drone. Try it and check, you might not have my connection problem. Just give it a try
thx this helped me too. But as you said(wrote) I heated it less for start 20 seconds but with a regular heat gun! I did not have the heating station.
EDIT 16.4.2019: down to 3 lights on the remote.
I had the same problem. Now work very well.
Thank you!
Others are doing it at 250 for a minute. Should i start with that v
Just currious... Would it be ok to heat the contacts on other side of board?
It works now. Thank you for the vedio.
Different solution for me. I disassembled most of it, minus the main board. The battery was at 7.4V. I put it on a charger and charged it to 8.2V. Then plugged it back in to check and I got the four running lights. Maybe it was the battery, maybe a loose or corroded connection. Who knows? It just pays to check if it is working every step of the way. This way I saved myself from potentially damaging the chip due to too much heat from the heat gun
.
What did you charge it with ? a regular S2 charger slot fits to the battery ?
@@BestForexBroker2024 i was wondering that too, I pulled it out and it's a 3s 4 slot connector on the 2s
So, all 4 dots lights up on my board when the battery is unplugged. But the moment that I do, only 1 dot is blinking. Any ideas on this? Does this mean that the battery is busted?
If only one light is blinking while charging the controller, that usually means it is only 25% charged. Keep charging and see if more lights light up. If not, you may need repair.
het werkt perfect :)
Can i use soldering iron?
Yes! I used a regular soldering iron (60watts I guess) for 10 mins!
I placed it directly on the IC the whole time! Worked like charm!
I would not use a solder iron, I would use a heat gun to Reflow
Trying that tomorrow. My RC only charges to 60%
Edit...had to do this a 2nd time only 3 lights charging again. This time I waited til I saw movement on the chip(solder releasing) with the heart gun 1" away for approx 1 minute 20 seconds. The heat gun says it reaches over 400° F
