00:16hi guys and welcome back to the vape mixer channel i hope you're doing okay because i'm doing okay
00:22too and i'm if this video looks a little bit different it's because it is i'm gonna do
00:28something a little bit different to a normal unboxing because i'm going to give you a little
00:34bit of an idea of my system and my setup i have here because the last video i recorded
00:43this happened this one we looked at which is the sigalike and for some reason my lights just timed
00:51out let me turn oh nope something just popped and i don't know what it was ah well i'll figure
00:56it out
00:56in a minute um oh i blew a fuse that's what you want
01:06and i've now looked around and i figured out what the problem was so this is my setup hello yes
01:14i'm
01:14holding the phone and this is where i record all of my videos and the light what went out is
01:21that one
01:22which is on the wall stuck over the top of my very obviously knockoff avenger poster
01:30and that is controlled by this little switch over here which i can turn it off and on with that
01:37um
01:39that thing's for the the ceiling lights which does do something that's up there that turns them on and i
01:47can
01:48change the color they're not great but they work um but yeah that's the light what went out in that
01:56video
01:57and um it's connected to this usb power thing ignore all the paraphernalia i've got a lot of projects i'm
02:07halfway through yeah it's plugged into this thing a five port mains powered usb charger and that usually
02:18powers that light and it has my phone charger and it charges my mics and everything with it
02:24and it was that what blew up well it wasn't that one in particular it was this one
02:34this is the one that went pop and gave me a little bit of a shock
02:40so i thought something a little bit different today let's um let's actually rip this one open
02:49and see what's gone wrong with this usb-c tower it's not usb-c it's just a standard usb but
02:57it's a mains
02:58powered five port usb charging tower and then this is what went boom so let's get this guy open and
03:10see if we
03:11can diagnose the problem okay back in our normal view and there's no visible screws on it but there
03:21is some pads on the bottom i'm going to guess either under that label or under these will be some
03:29screws
03:31yeah we've got some screws on here
03:35it's going to be four of them or five of them
03:40now when this went if you watched the video where this actually did pop it went with quite a loud
03:48pop
03:51and it gave me quite a little shock like not bad electric shock but it was enough to startle me
04:01through the plastic case which isn't good i don't think there's a screw under that label i can't feel
04:07one i need a screwdriver
04:14oh my screwdriver's got away let me see we can shift them
04:18what's a star that's a flat head will you fit
04:25nope that's too big somewhere i will have a screw that will fit
04:32this one might do it
04:37yeah there we go
04:41so i am not interested in saving this thing i'm not interested in fixing it i just want to know
04:48what went wrong and screw gun on the floor i just want to see which bit of this went pop
04:59because i'm a very curious person
05:03and i do also need to say this is about two years old
05:08and i think i paid 7.99 for it the bottoms flew off
05:17and i have not seen one of these before so um
05:22there is a lot of capacitors in there
05:31the fact that there's so many capacitors and there's so many big capacitors
05:37is a little bit worrying because i don't know if they would have discharged it has been unplugged
05:43for a couple of days so it should have decharged let me just um
05:52i have no idea where that went
05:56there it is but um
06:00it's free
06:09this is kind of cool
06:15i mean at first i thought it was a fuse what had blown
06:21i'm seeing what the problem was i can see the problem
06:29i'm definitely seeing the problem
06:34what is that white stuff on there
06:39it's like a white gunk
06:51okay so i'm actually seeing a couple of problems here
06:56now the reason i know that it was this what failed is because as i just shown you i have
07:02a second one
07:02over there which is currently powering the light giving me a light over my desk
07:10and i can see a few things
07:16there's a few things which are causing me concern
07:20and then one thing
07:23which i think is a definite problem
07:32so let's try and point these out so
07:36that one is fine
07:39this capacitor
07:42none of the gates on the capacitors are actually blown but
07:46one of the panels two of the panels on this one
07:50that panel and that panel are slightly puffed
07:54one panel here is puffed and all three on this one appear puffed
08:00the rest of them all look
08:05perfectly fine so we've got three capacitors
08:12which look like they were on the verge of blowing up
08:19now i don't think there will be any more power in these this is a rubber handle so
08:28i'm just going to bridge some connections just to make sure
08:36just to completely discharge everything
08:41if it isn't there we go
08:44so yeah a few of the capacitors are puffed out a little bit
08:50big resistor and we've got a couple of transformers
09:02hold on
09:09i'm just trying to figure this out because it looks to me
09:15is that wire actually starting to melt the insulation on that wire
09:21look at this wire
09:28it is
09:31the insulation off that transformer wire is actually melting up
09:35this one that's actually split on the other one
09:42the insulation on that split it's melted away
09:52you know what the more i look at this the more worried i am i am about using that one
09:58what i'm using at the minute
10:02but uh let's flip it over and i'm going to show you the bit i think popped
10:09and i'll give you my thoughts on what i think actually gave me the little
10:16jolt but look at this control chip right here if we can get it to focus
10:25that has it's blown a chunk out of itself
10:33that's a proper chunk missing from that
10:40and look at the bad soldering on there as well
10:47i mean i don't know if that is how they're supposed to be but
10:52you have one connection here for one of the transformers
10:59which is soldered to three of the pins of that blown chip
11:06and to this little other chip here which is labeled d11
11:13so you've got one big blob of solder
11:17that's just bridging that chip it's right it's one blob of solder that is connecting the transformer
11:27one pin of one chip and then three pins of another chip it's bridging all of them
11:37how did this even work in that condition
11:43and again down here look at these two that's two separate connection points there but the solder has
11:50bridged and created a short let me get some a bit more straight these two here
12:00now looking at it they should be separate separated like these two are but they're not they're bridged
12:07in fact the soldering job on this is so bad look at the soldering on this chip in fact even
12:13this chip
12:16even this chip's blown a tiny chunk out of itself
12:27oh no wait there's one of the same chips down here that also has that same dimple so i think
12:32that's part
12:32of the design to ignore that one but this chip here that has definitely blew a chunk off
12:43so many bad solder connections
12:48in fact look you've got this up here and then you've got the exact same setup down here with the
12:54solder connecting the two chips and a transformer so maybe that's how it's supposed to be
13:03like the same down here it just looks very unusual to me
13:09but that chip that is controlling the transformer
13:16i'm going to guess as to what happened here so i'm going to guess this chip blue and the power
13:24in this
13:24little transformer had nowhere to go because it was so close to a very thin plastic sheet
13:31like look how close that kind of is to the top so when i put my hand on the top
13:37it's kind of just
13:39art straight up through the plastic into my hand
13:44that's my guess as to what happened
13:48but yeah still interesting something a little bit different for the vape mixer channel
13:56i just wanted to see what went wrong with my setup and i think we have a pretty good idea
14:02so um yeah right i'll see you in the next one then so like comment subscribe follow all the usual
14:10stuff
14:10and i'll see you next time okay bye
14:14you
