Hello I'm Graham and I hope everyone's having a great day and
welcome to this video now in this particular video I've got a Panasonic
Lumix TZ10 or ZS7 for
the American market now this one has a sticking lens shutter you might just be
able to see from the image now that there is a gap between the shutter and
sometimes when you turned this camera on the shutters don't open all the way so
if I just turn that on now they're broken contrite enclose it again the
shutters aren't closing correctly so that's allowing dust to get into the
lens now it's a fairly easy procedure to actually strip this lens shutter down
and clean it and that's what I'm showing you in today's video now the tools
you'll need are a small flat bladed jeweler screwdriver a pair of tweezers
sharp knife that can be a craft knife or a double and a brush just to clean out
any debris from the lens shutters and when you come to reassemble this you
might want to use some double sided tape or as I've been using recently glue dots
to be able to adhere things together again
so let's start the procedure of removing the lens shutter from this camera now
what I like to do is to turn on the camera so the lens extends and then
remove the battery so now the lens will stay extended and there's no danger that
after the economy period the lens will try to retract so we've now got the
battery removed and what we're going to do is to remove the bezel from the front
this lens now this bezel appears on the tz6 seven the tease at 65 the tease at
10 and the tease at 20 and it's that bezel we're going to remove to gain
access to the lens shutter now to remove that bezel it needs you to use a scalpel
to go underneath the plastic lip and the edge of the aluminium bezel and the
bezel is held on by some sticky tape double-sided sticky tape and it's that
tape that we have to break and to be able to remove this lens battle so
what you need to do is just take the tip of your scalpel just run it underneath
that aluminium fascia to break that double-sided adhesive tape that's
underneath there taking the scalpel all the way around that lens barrel
right now I've been around the whole of the periphery of that aluminium bezel
and now should be able to just pry it up and release it from the double-sided
tape right so that is the bezel removed now to remove the lens shaft that we
need to remove this plastic component here at the front of the lens and it's
held in place by three little Clips now we need to remove those clips and the
best way to do that is to use a flat bladed screwdriver and just go in the
back of the clip and lift it off its post
and the third one and now we can remove the lens shutter now it will only go
back one way but it's worth looking to see if there's any identification marks
and here's the serial number on the top of the lens shutter and that's to the
top of the camera so it's worth remembering that and you can then get
the orientation correct so we'll remove the lens shutter and just put the camera
to one side now if I turn the lens shutter over if i zoom in a little bit
so this is the actual lens shutter assembly and if you're noticing on the
assembly is a plastic peg and that is driven by a cam with inside the lens
assembly so as the lens retracts it turns this peg to the right hand side
which then closes the shutter and as a legacy lens extends that cam drives back
on that peg moves back anti-clockwise and allows the shutters to open now as
I'm operating this I'm actually seeing some debris coming out to the lunch
after you might be able to see it here on the table so it looks as though this
has been in some Sun or something like that which has got in between the blades
in the tracks that these rolling now you can't fully dissemble this and it means
just removing these two Springs on either side and if you turn this peg
completely clockwise at the end of the track there's a notch which allows you
to take it off the assembly in this case I don't think I'm going to need to
remove the whole of the shutter assembly I'm going to try and brush it out from
the front and rear of the assembly so if I turn the shutters in and then I use my
soft cam hair brush I'm going to try and brush anything from within the track out
of the assembly and we'll just clear that debris away and we'll do the same
from the inside
now I've seen people say lubricate these but that's the last thing you want to do
with this shutter assembly you do not want to apply any lubrication to this
they must run dry but you might be able to just see there on the shutter blades
there are some scratches which indicates that that sand or grit has been in this
assembly for quite a while as it started to mark the blades as they go in and out
well that looks as though we've got a good result because the lens shutters
are now closing perfectly nice spring action on them and there's no stickiness
we'll just go around that one more time so this is where a blow would come in
but unfortunate just cannot put my hands on my blow it's normally in my repair
box but I can't find it not very tidy at putting things away now while we've got
this lens shutter removed it's worth having a look around the lens itself and
make sure there's no debris in the lens as these cameras are quite prone to
gathering dust so while the lens shutters are removed it's worth giving
the lens are clean and first of all I'm just going to clean the front surface on
the inside of that lens assembly again I'm doing it downwards so there's no
dust or sand falling inside the camera now I'm going to inspect the lens
surface it looks quite clean there doesn't seem to be anything on there but
well it's apart I'm just going to use the lens pen to circulate around there
and clean off any fingerprints or dust which may have settled on the front
element of that lens
yeah they're working fine so again with the legs extended just remove the
battery to keep that lens out we're going to reassemble the front bezel and
I'm going to use some double-sided tape so I'm just going to cut two small
pieces for the top and bottom of the lens that's going to be the first piece
place on the top of the lens I'll just remove the buckypaper
like so and then the lens bezel will just clip over the lens and I'm just
going to smooth it down with the back of this brush to make sure that it adheres
again to that double sided tape and this camera looks as it has been in the wars
it's got quite a few dings on the front of that fascia so we'll just reinstall
the battery now and make sure that that lens our tracks completely inside the
camera that the bezel doesn't bind that looks fine I've got some isopropanol
lens tissue here I'm just going to try and clean up some of the fascia it has
been previously damaged so we're not going to get a perfect finish but we'll
try and improve the appearance of it
and then just check cameras working fine
and that's it so that's how to free up the lens shutter of the Panasonic Lumix
travel zoom cameras the ones which have the removable front bezel now later
cameras like the T's at 30 and 40 don't have that facility and you've got to
strip down the lens to enable you to get to the lens shutter so that was a
retrograde step in the manufacture of those lenses where it's so much easier
to be able to clean those land shutters by removing that front lens bezel so
that's it for this video thanks very much for watching please do take care
and hope to see you all in the next one good bye for now
