Awesome, thanks for this repair guide. I just successfully repaired my HDZero Race V2 by replacing a damaged 22uH SMD inductor on that 5V dc-dc step-down circuit. Luckily the IC (TPS4302?) was fine.
Awesome Ian! Love these kinds of videos since I do board repair also. I had hit up this user to buy these broken boards, but he had sent them to you that day! Great to see you got one of them working so far. Excited to see the others also!
Nice diagnosis and repair Ian! I had to cringe a bit when I saw the boards were sent to you taped to printer paper though...lots of potential for ESD damage. Nevertheless, I'm really enjoying your HDZero troubleshoot and repair videos. Please continue to post them. Thanks!
Why do you have solder-leftovers on your bench while testing pcbs with power connected? That was quite hard to watch! Nevertheless I enjoy learning from you 👍
I have a whoop board with a similar issue to #4 LEDs light up fine, but no video. I also have another one that is OK for ~20 secs but then the video cuts out, but again, both LEDs still lit. Are you planning on making a video regarding the whoop boards?
Can a patch antenna be used for TX? On DJI, everyone says put the two patch antennas on the bottom ports. One of those two bottom ports is a TX _and_ RX, for requesting retransmissions. Is it a waste? Will it transmit further than the omni? Can a patch even be used for TX?
I have a whoop board that turns un but no video signal, can’t wait for you to troubleshoot board #3 lol, keep up the good work 👍🏼
Good stuff, can’t wait for part 2, 3 and 4!
These are really awesome videos.
Reminds me of when Louis Rossmann still repaired boards :)
You have the skills, thanks for doing this!
I love these repair videos Ian!
love watching these
Good job Ian. Nice video.
Please keep making these videos I have about 5 dead whoop board

This is really good stuff. Nice to see how we can troubleshoot these electronics, really educational. thnx ian.

Great work Ian,just the sort of series I love,looking forward to more.
Really excellent work, Ian! 😃
I really need to get a microscope and a hot air gun!!!
Stay safe there with your family! 🖖😊
you can get by with flux and a lot of solder wick
@@terminsane That's true, but it's a lot of work! 😬
More videos like this!
1 minute in and I'm going to place a bet that #2 is going to be the MIPI Encoder

I kept fidgeting in my seat wanting to say brush it aside
