all right i'm dave rat and normally i am sharing all kinds of cool info about pro audio touring and
sound systems and today i thought i'd share something different had a broken toothbrush
and um decided to take it apart and see what's wrong actually it's a philips sonicare hx686
and with a letter after it p i think and contacted the company they sent a new one
because the toothbrush was this one it's all loose it wasn't working right it was just um
something was loose inside something broken or whatever called them up they're really cool sent
me a replacement and they sent a 684 a instead of a 686p uh almost the same thing a little bit
different then after i got i was like well let's take a look inside and so i opened it up and
checked it out found the problem and was able to fix it i actually put it back to where it was
put it back together um and then i looked on you figured out take a look around youtube and there's
a bunch of people that have shared you know how to tons of videos out there how to open these things
up and almost all of them involve some sort of like damaging like they want you to
pick at this thing with a screwdriver and jam it in there and pry the back out
or get a big pliers and squeeze it and it may work for other models i don't know but
there's just a much easier way of doing it so i thought i'd share a simple fast and easy way
to get into these things and at least fix this problem or get in and see what the problem is so
let's do it um take off the head and pretty much what we do is get this bottom part off i thought
maybe it was a label i could peel off and there'd be some screws there there wasn't i figured that
would come out instead of prying this thing off with a screwdriver and trying to jam it in there
and tearing this thing up what i did was i just got a standard quarter 20 um bolt um one of the
most common screws uh available um may have some laying around the house use them for everything
and this little charging port here is plastic and turns out that screw fits in it threads in there
pretty well it digs into the plastic a little bit i just pushed it in don't turn it too much
you don't want to slip just turn it just enough to get it snug and then pull and the back comes off
and you don't have to damage the unit at all um i'll go ahead and leave the screw in there then um
i saw i had all those guts in there and after looking those two little clips on
the side i'll show you in a second soon as i get them out real simple to get those out is
okay so you just take those screwdriver put it in there so let's turn that thing on [Music]
okay so there's two little tabs in here and if i take the screwdriver i can just put it right
on the side of the tab and i can push down on this and i can put it on the other side and once
i've freed up the two tabs um it'll pop out and to show you what those tabs look like oh then we get
all these guts ooh look at that battery and all kinds of electronics these two little tabs um are
just little springy things and on the side of them there's plenty of room to get a screwdriver
in there and just pop them off the side and then on the inside here there's two little um
you know hooks that kind of stick out and a little flashlight in there it's pretty easy you can just
get alongside those two little black tabs and pop them out all right so now we got the guts out
um and we can pretty easily see this is the problem here at least on this one if you have
some other problems or broken stuff or you're changing the battery now you're inside you can
do that inside of that thing take it out and there's a little screw right there and
this is a number one phillips which fits right into that screw as soon as i tighten that screw up
boom let's let's try it turn it on and there we go it's um it's done uh so what i'm gonna
do instead of just um tightening it up because it was a problem is i'm going to
loosen that screw up i was going to take it out but i decided against it because i
don't want pieces to fall out i'm going to take a little bit of um loctite here
and i'm going to put it on dab it onto the threads
and
screw that screw back in
and
now it's not only fixed but it's not going to come undone at least in that same way and then
to reassemble wherever the light is or the buttons you line it up there push it in it'll pop it snaps
in and then this here pushes back in and we can undo the screw and throw the head back on boom
um that's the 686p the new one figured i'd take a look in there and see if it opened the same way
um did the same thing take a screw tighten it in there by hand with the pliers
and pop the back out now if for some reason you over tighten it or it's not going in quite right
uh or you're not and that'll able to take it out um i've done this before with other
things i don't remember what it was but i've used this method take a piece of paper and fold it up
a bit until something that's and just stick the paper in there and then
use that as a spacer and then screw the screw in with the pliers or with your hand
until it wants to stop spinning and pull the end out um and let's take a look inside of this one
same thing see if i can get in a little easier
there we go and there we go this is the inside of the other one um i'm not going to do it i could
lie it wasn't so easy to get in i'd actually loctite this but i'll just wait for it to break
if it does do the same thing um cool yeah these things are kind of expensive uh not too bad
um but way into the fix-it adventures and not throwing things away
and thank you phillips for sending us the warranty repaired or warranty replacement good way to
operate a company it's what we do with sound tools and um it is um great to have the spare
and thank you for letting me keep the other one so now we've got um i don't know spare cool all right
and i'll get back to audio and off of these divergent subjects thanks for joining
[Music]
hmm
you
