After successfully activating it, I was positioning a brand new V3 about 6’ up, magnetized to some metal, when it slipped off and hit the concrete ground.
It would not turn on or work at all (no LED light or anything, holding the setup button did nothing at all, etc), and sometimes I even heard a sort of rattle when I shook it, so I thought I broke something.
Rather than throw it away, I figured it couldn’t hurt to open it up and see if there was something I could easily fix.
When I opened it up, this is what I saw:
Well, that made it a no-brainer on what was likely wrong…the fall had obviously knocked loose that power plug. So, obviously, if I plugged it back in, it should work again.
So I did just that. I connected the power plug:
Note that there wasn’t a ton of extra cord length to work with. In fact, it was actually twisted several times pretty tight, so it was originally much shorter and more tense than you see in these pictures, these pictures show it already untwisted so that I had slightly more length to work with (after fixing the camera the first time and verifying it fixed the issue, I disconnected it again to document and take pictures to show everyone what I saw and how I fixed it).
After connecting the power cord, I pushed the casing back on to cover the electronics:
Then I put the screws back in, and replaced the little rubber screw covers:
Then pushed the white cover back on it.
In that picture, it is slightly sticking out so people can see how to take it off.
You can use a razor blade to pry things out, I personally used this:
[A metal spudger], but I would probably recommend a hard plastic one or a hard plastic guitar pick instead if you have one to help prevent scratching. I saw others used a razor blade, and I started with that, but it seemed to cause more damage easily, so I switched to the spudger.
Thankfully I didn’t just throw away the camera after dropping it and thinking it was just broken, when the fall had actually just knocked loose the very tightly wound power cable.
So, if anyone’s camera suddenly stops working entirely (no status light or anything), Consider opening it up by following those pictures in reverse (you just have to squeeze a tool in between the little cracks to pull on the little white cover and the black part after unscrewing it to get them to pop out), and checking that the tightly wound power plug didn’t just spring unplugged. It might just be a relatively simple fix.
(To clarify, I didn’t contact support about a warranty for this brand new device specifically because I knew the problem was caused by a drop that was 100% my fault and nothing to do with some kind of malfunction during normal use [like warranties are intended for], and for me personally, it was an integrity situation that I personally would not have felt good about pursuing in this particular case).
I post the above just in case someone else ever has a V3 that stops responding 100%, because it could just be that the tight-pulling power cable jostled loose like it did with mine, and it’s not too hard to fix.
There are further explanations and suggestions in the following posts. In short, try to keep the double-sided tape all together when prying off the square little front white cover by pulling it off slowing and pushing the stretching tape up against the cover as you go all the way around pulling it off slowly. Also be careful not to accidentally cut up the little red gasket that basically makes the device waterproof (IP65). Don’t worry about it too much though…even if you mess those up, it’s not a huge deal, it’s just preferable to be kind of careful so that it’s good as new.
