MF#10 inside the yamaha tyros 4 keyboard teardown

today Jason Lee who's known as Olga not

on youtubes got loads of videos on there

is actually brave enough to let me get

inside this tire offs for of is what

we're going to have a look at well I

mean I've been playing it for couple of

years now now always wondered what's

inside it I like to know what makes

things take and it does a hell of a lot

of it sounds wonderful boy it would be

nice to have walk inside Robin yeah

what'd you do we know you do we're gonna

have a look at why the memory costs over

a hundred quid for a gig of memory and

well just have a look around inside so

screwed a little so we're going to look

inside the Tyros for this is the 10th

anniversary edition so it's got black

plastic instead of silver plastic and if

you're watching this in a couple of

years time your avatar or six or seven

or god knows what but this has already

been superseded by the tyrus five with a

few little changes here and there but

let's stop nagging and get the

screwdriver up one good thing with these

Yamahas is you've got a land connector

your USBs if you know you can plug this

into the internet and download different

things for it directly RGB output a

standard composite video and output and

then all your typical jack sockets etc

for your audio in and audio out line

mike import etc so they come well packed

with a you know a lot of extras on there

okay I can flip this over and try and

figure out how we're going to get inside

it without using a hacksaw on the

anniversary edition the black one the

expansion memory already comes as

standard now you open this little plate

and there's a huge hole there so you can

keep your sandwiches in there but anyway

this is your flash memory expansion

module just a cup a little

screws and out it comes now there's been

a lot of chatter about their memory this

costs over a hundred pounds it's only

one gig of memory the chips are not even

Yamaha branded but you know what is

special about it what makes it a hundred

pounds or 120 pounds I really don't know

on the Chronos they call some of the

Korg stuff it just takes standard

computer memory you can buy this for 15

quid 18 quid or whatever is one gig and

you just sort it in you know you don't

have to buy it from Korg but I don't

know maybe they're doing something

special there but uh nothing

come on yeah my horse I'm for a hundred

quid for a Giga memory

blimey just here which will be the

bottom right of your keyboard you don't

do three screws and then this little

drawer comes out and this has got your

hard disk on it what is this aha

it's just a standard Toshiba hard drive

and this it looks like a micro USB


yes it's just little micro USB there's

your little controller and a Toshiba

hard disk that's a standard size that

you find in most laptops and things and

I guess you could just buy a bigger one

if you wanted to and actually replace

that any brand or model so that's handy

nice thought there right there's plenty

of screws underneath around the edge

that you take out they just screw

directly into the plastic and then

there's four machine screws along the

centre once you've undone those I

noticed it moved so I flipped it the

right way up and we'll figure out how to

get into this alright it's lifting up

pull forward a bit get it over those

keys now I don't know where any of the

cables are in this so I don't want to

lift it straight up just yet

I get my head under there oh yeah

that's okay we can just drop that back

okay now that's just lucky that that

happens to sit there and hold it so far

I haven't already done this but anyway

this is the inside of your Terrace for

some nice shielded cans here this is

obviously going to be your power supply

power goes in here and disappears into a

cam there there's a board underneath

with all your jacks ins and outs and

well this is obviously the computer

section so we'll get these lids off and

have a look on today Oh earth keyboard

yeah just to spend a keyboard it's got

the little rubber push buttons there

that make contact with the board with a

sort of a carbon film on it and

underneath where is oh it comes in from

this end the aftertouch ribbon is

running under here where this black

where that red felt is sort of got the

after touch ribbon underneath there oh

yeah very nice okay very neatly laid out

okay we'll move on and have a look

inside the power supply not what I tend

to do is every time I open something up

that I have not been in before before I

stopped pulling off cables and

disconnecting leads and things I just

either get a camera or I use my mobile

phone camera and I just take a few

pictures of where the cables are going

where the plugs are going and just a few

snaps even there wherever there's a few

plugs and sockets just take a few

pictures so on and so forth that way

when you take it on par and you start to

reassemble it and you're left with a

lead you know the know where to go you

can just have a look through your

pictures and hopefully

you've got a clue as to where everything

goes again

put it back together I have made that

mistake a few times in the past but you

learn by your mistakes down here anyway

we're going to have a look inside the

power supply now I've taken the screws

out of these bits of metal and this what

we assume is the power supply and as you

can see what I tend to do is I try and

put the screws down in some sort of

constellation or a little map so there's

an idea where things are going yeah it's

good practice to do that if you've got

different sized screws so anyway let's

get these bits of metal up and see what

we've got hiding under here oh yeah very


whatever huh I want to get inside here


here we go there's your tyres power

supply ah so you've got all your little

voltage regulators here there's not a

heck of a lot of capacitors on there a

few it's chokes and whatever a couple of

Goff +5 volts plus 12 volts minus 12

volts and plus 3.3 volts sort of

standard fuse there and yeah there's

lots of power regulators hmm nice nice

and neat so Nippon Nippon capacitors

good quality yep so there you go there's

your power supply very nice moving along

here you've got some serious resistors

yeah 22 ohm resistors and then off he

goes into whatever is interesting under

here okay let's get this off

we've taken 11 screws out of this thing


see what's under there whoa whoa pretty

yes oh yeah have we got going off in

here there's a lot of Yamaha chips on

the board demo heart branded with just a

code number I don't know what these

codes are for I think what they're doing


is the same as what you look Packard

does with some of their chips they get a

chip and they have it rebranded with a

number on for them to understand this

one is suspiciously an Altair a cyclone

because the same number chip is used in

a Steinberg audio interface with the

Yamaha written on it as far as I know

these are memory modules it's exactly

the same chips as what's used in the

expansion memory that you buy little

Texas Instruments here these lb 2 4 5 a

the octopus transceivers with three

state outputs you've got seven 805 our 5

volt regulator yeah everybody knows that

one it's 2010 Yamaha chip they're the

USB it's coming down to an a6 USB

controller ah but there's not really lot

to talk about that it's all very nice

and neat and they tiny look yeah very

nice let's move on to something else

anyway after you've got all the plugs

out here there's one little screw on the

back that's stops you from lifting this

oh so oh yeah that's the bottom side of

the board there's a bit more memory here

that's where your module sits for your

expansion memory this is a LAN

controller and USB VGA or whatever

controller yeah very nice nice

double-sided board that is

this is the main processor r8 a 7 7 3 1

ody or 0d renesis will Reynes us haven't

got clue what it is

I've just had a quick search on the

internet and nothing's coming up just

spare parts for a Mazda car which

obviously I very much doubt that is ok

nevermind things are being kept a secret

here for us right I've put the cans back

in place and yeah I like the Detailers

going off in here you've got little

ferrite rings all over the place but

anyway the only piece I'm not going to

bother taking out is these boards

because all they contain is push buttons

and LEDs on the other side that's

already a row of sliders there you can't

get to the monitor the monitors an

external piece so we'll just pop this

back into place in the moment and then

magiclip mine under there

there you go clumpsy nicely ah yeah

monitor is nice monitor on these can

sort of just drop it wherever you want

I don't know why they haven't bothered

moving on to touch screen on the tyrus 5

a lot of keyboards now that's got a lot

of information here are using

touchscreen Yamahas response was well

people are used to this now so we're not

going to bother putting the touchscreen

on that's fine but you're sort of

standing still you're not moving forward

so you know you've still got your clicky

pushy buttons down the side of the

screen to operate there not one other

thing which i think would be better for

Yamaha is they've got this idea of these

are your satellite speakers ok and what


is you have these little holes here and

the pins marry up to the little hole and

that pushes into place and then you know

you can position them where other but

they we've got these plugs on the back

no they they look messy you know you put

that into there and then you probably

actually into the key keyboard there it

yeah it doesn't look very professional


Yamaha come on do away with that that's

rubbish all you should have stolen it's

got metal pins on it to you know put the

connectors in there so that when you

plug the speaker in is connected I mean

that that's going to be very easy for

you to achieve and that looks so much

neater doesn't it you hunger all these

wires going everywhere like an

afterthought well I think you know you

should seriously consider you're using

two metal pins anyway you know make the

speaker connection there so you can plug

it in and it's done okay that was just a

brief look inside the Yamaha Tyros for

you know four thousand pounds worth of

keyboard this is but as long as it

lights up I'm happy that I've put

everything back together again there you


oh well enjoy they're quite expensive

these keyboards that cost a lot of money

but you know the amount of stuff you've

got in there drum machines and electric

pianos organs strings brass all sorts of

stuff it's a good all-rounder

entertainment keyboard you don't need

much more than this to entertain with

well anyway it was a nice brief look

inside the Yamaha for those of you that

always wondered what was in there and

what's next don't know I'll find

something thank you very much for
