Fitbit Sense: Sense won't power on or sync

Thu, 13 Jun 2024 13:11:49 -0700

My Fitbit sense won't power on. It's been on the charger all night. I've tried all troubleshooting tips and nothing! Holding button for 10 seconds or more,cleaning connection with alcohol wipes,left on charger,tried a different charger and used laptop to charge. Restarted my phone. I uninstalled my Fitbit app,,turned Bluetooth on and off. Any other suggestions? When I go to the app, it won't sync to my s21 ultra phone. Can I take apart this watch? I've had it over 1 year, so probably no warranty.

Fitbit Sense: Can I reattach my Fitbit Sense watch screen?

Tue, 24 Jan 2023 03:24:49 -0700

I woke up yesterday and the screen on my watch had disconnected and was just dangling. See photos. The display disconnected from the case of the watch. It's still connected by the cable connectors, and the screen is still working, but I need to re-adhere the display, if possible. Can I just add some adhesive and reconnect it without having to replace any parts?

Fitbit Sense: Fitbit sense in boot loop.

Fri, 28 Oct 2022 20:05:16 -0700

My Fitbit sense was working fine during a typical day. I had gotten a phone call on my iPhone and my Sense indicated it OK. After the phone call was complete the Sense still indicated the answer/cancel menu. I hit cancel and everything crashed after that. Now when I try to reboot with the USB jack plugged in on charge I get a brief indication that there's a connection with my windows computer after the screen goes blank but then there's a disconnect and the boot screen comes back. I tried letting the battery run down completely and then doing a recharge to maybe let the CPU reset but I didn't have any luck. My guess is that this is strictly a software issue but I've had no luck getting the Sense to restart properly. Opening up the watch and disconnecting the battery was another idea that I had but that hasn't been attempted yet. I have the tools to open up the Fitbit Ionic and have changed the batteries a couple of times in the past but I hear that doing that with the Sense is harder. At this point I have nothing to loose because my Sense in bricked and I just bought a new Apple watch. I like trying to fix electronics stuff and wouldn't be afraid to give it a try.

Fitbit Sense: Heart Rate sensor not working

Fri, 14 Apr 2023 18:45:15 -0700

Hi, my Fitbit Sense Heart Rate green light stopped working last week. I have tried everything from the tips online to factory reset. Everything else works fine. Without the heart rate indicator, however, the sleep score and more detailed exercise tracking does not work.

Fitbit Sense: Torn ribbon on lcd…

Fri, 02 Feb 2024 06:06:11 -0700

Hypothetically, if while in the process of trying to repair their Fitbit sense (cause the screen fell off even on the bloody replacement!), someone managed to tear the ribbon on the new lcd screen, would there be any way for them to fix it?

Hypothetically, of course.

Boy-o-boy that would be pretty stupid of them to hypothetically do!

And I bet it would hypothetically look a little something like the attached photos…

Anyone with more brain cells than myself got an idea on how to reattach? I mean it wasn’t working when I first installed it anyhow so could be some motherboard issues which might make it better off a write off but maybe maybe?

I mean, hypothetically, of course.

Thanks for anyone who explores this fun thought experiment (and definitely nothing else) with me! \(^o^)/

Fitbit Sense: Is it even possible to fix the charging issue?

Fri, 21 Jul 2023 15:51:47 -0700

I have worked on this one for someone twice and it is happening again. What happens with this watch is at some point the charger has connection problems and it will not charge without cleaning with contact cleaner. I’ve tried to save the watch again but now it no longer stays on, or refuses to charge. Not my first rodeo with Fitbits, 2nd one with this issue.

Is there any way to even save this watch or have I hit the limit on this watch and it’s dead? I feel like these Fitbit watches are hopeless in terms of repair as I have not found a good way into them.

Fitbit Sense: Spare LCDs not coming with an NFC cable?

Tue, 29 Nov 2022 09:48:29 -0700

Hi team! I want to replace the display on a Fitbit Sense.

When trying to buy the spare part, most of them look different than what is seen in this guide, seems like they don't come with that second flex cable (for the NFC).

There's 1 supplier I've seen that sells LCD that seems to come with that 2nd NFC cable for the Fitbit Sense, but it's more expensive than the 99% of the other LCDs sold that seem to just come with one display cable.

Will that be a problem and make Fitbit Sense lose NFC/wireless payments if we replace the LCD with such parts? Or is there a way to transfer the NFC cable from the old LCD to the new one? Or do I NEED to buy the LCD with the second cable for NFC included? Or is this maybe a difference between the Fitbit Sense and Fitbit Versa 3? (as the LCDs are advertised as being compatible for these two)

Any thoughts are much appreciated. Thanks in advance! :)

Hi everyone! So I received the part I bought from AliExpress with the NFC+LCD. The repair was super easy and straightforward. The NFC is a piece similar to a wireless charge coil from a Samsung phone but tiny. It's adhered to the LCD's back, but it's definitely removable and swappable. So if anyone is in doubt, just get the LCD and swap the original NFC coil onto the new LCD.

Take care! :)

Fitbit Sense: Will the speaker and mic still work if I seal the ports with silicone?

Sat, 31 Jul 2021 11:57:00 -0700

While cleaning the speaker area I think I may have damaged the screen covering the speaker compromising the water resistance. If I were to seal the port where the speaker is, and I think the mic is right next to it, would the mic and speaker still work or would the silicone create a barrier that sound will not go through?

Fitbit Sense: Transferring NFC cable to new lcd screen

Thu, 21 Aug 2025 07:25:11 -0700

Hey all,

Planning to replace my sense screen, but cant find any tutorials that show how to do this. I have found one video where it is done but it is unclear to me what is going on and the VO just says remove thin ribbon and attach to new screen. He appears to be prying something up and then just sticks it on the new lcd. He doesn't appear to be fitting it into or on some contact point. Is the nfc cable just connected on the mobo? And then just anchored to the back of the lcd with out actually plugging into the lcd? Any guidance or reference would be appreciated.

Thanks,

Billy
