Close Up Disassembly of FitBit Charge 3 

Unfortunately I get to these comments so late. All the same, I did not have any success repairing my fitbit. I believe the main board got damaged and that was beyond my abilities. I could have bought replacement parts, but for a good portion of the cost of a new fitbit, it wasn't a guarantee. Additionally, I had another fitbit charge to use. Ended up killing that one the exact same way. Now I'm rocking an Inspire 2. Smaller, same functionality, much more replaceable because it's 40 to $50 cheaper, and the sensor module seems redesigned to be more robust. I've been going strong with the inspire 2 despite it being exposed to some hard working conditions.

Check out "iFixIt". They have their own tools and they have a variety of repair videos as well. They are good quality and are a reasonable price, but you can find cheaper. I have had their "Pro Tech Tool Kit" for 5+ years and it has been very handy!

I used an "RTV" gasket maker. It's a kind of silicone adhesive that comes in a tube and is very resistant to chemicals (it is often used in car engines, for instance). I used it because it was what I had, but also because I believe my sweat may have broken down the gasket on two previous fitbit charge 2's. I bought the cheaper, less feature rich fitbit inspire (2? I think) and it seems to be made much better, is smaller, has a way longer battery, and is much cheaper. Haven't had any problems since.

@decsprojects2297 RTV sealant, didn't cross my mind ( genius), thank you very much for this tip 😀 😊. I work in vehicle repair industry ( accidents repairs), I should av think of that. Brilliant idea 💡.

Is this electronic psychedelia with 70s soft porn influence? LOL IDK what it is but it certainly makes this more mesmerizing to watch.

You're spot on there, lol. I get all the music off the Audio Library that youtube maintains. Free to use, etc. I binge listen and download my faves. I have folders and folders vaguely organized by mood.

i do too, lol

I used a silicone gasket maker. Searching for "RTV" should get you there. I went with something oil proof because I had a suspicion that oil from my car had broken down the old seal.

@@betterdoneright Do you think T-8000 will be sufficient? I'm worried on the oils from sweat will break down the silicone adhesive.

@@OmarMatthewReyes I wonder this too. What did you end up doing?

@@darrenwilliger I still went with the T-8000. It's holding up so far, and is able to survive taking a bath.

You probably know more than me on that.. But google tells me that t-8000 is epoxy based, and I imagine that would be solid. Maybe not good for a gasket?

Not too sure! Perhaps we have different versions of the same model. Or maybe one of ours is more integrate?

@@betterdoneright Yes maybe, anyway I unstuck the digitizer from the old screen and stuck it to the new one, it works fine. Thanks for the disassembly video.
