Introduction
Les fans d'Apple font la fête, car il y a eu une foule de nouvelles annonces à Cupertino aujourd'hui, y compris une nouvelle Apple TV, qui n'avait pas été renouvelée depuis trois ans. Nos ingénieurs chez iFixit n'étaient pas moins contents, car ils ont mis la main sur une Apple TV de 4ème génération. Alors que le démontage commence !
Alors ne changez pas de chaîne, sauf si vous cherchez plus de nouvelles sur notre pageFacebook, Instagram ou Twitter.

Nous aimerions commencer par certaines spécifications et ici beaucoup de bonnes choses sont emballées dans la nouvelle télécommande. La boîte elle-même contient :
-
Processeur Apple A8 dual-core 64-bit
-
Ethernet, 802.11a/b/g/n/ac Wi-Fi, récepteur IR et connectivité HDMI 1.4
-
... alors que la télécommande contient :
-
Surface tactile en verre
-
Microphones doubles
-
Accéléromètre et gyroscope
-
Bluetooth 4.0, émetteur IR, connecteur de charge Lightning
-
-
-
L'Apple TV a réellement pris quelques kilos depuis sa dernière itération.
-
Elle semble avoir perdu un port dans le feu de l'action – la sortie audio optique est passée aux oubliettes.
-
Nos spécialistes en vues éclatées se mettent au travail sur l'Apple TV et trouvent rapidement la porte d'entrée, en bas de l'appareil – comme sur l'Apple TV 3ème génération.
-
Seuls quelques clips en plastique sur notre chemin, à part cela, ni adhésif ni vis à l'horizon.
-
-
-
Sous le capot, nous découverons quelques vis Torx.
-
Un petit tour de tournevis Pro Tech et nous sortons la combinaison dissipateur de chaleur/blindage électromagnétique (EMI).
-
En y regardant de plus près, cette plaque sert également de support, ce qui donne aux clips sur la partie inférieure quelque chose à verrouiller. Ça fait trois fonctions pour un composant, les amis !

Voici quelques puces composant votre Apple TV :
-
Système sur puce Apple A8 APL1011, avec LPDDR3 SDRAM de 2 Go SK Hynix H9CKNNNBKTBRWR-NTH
-
Module Wi-Fi Universal Scientific Industrial 339S00045
-
Contrôleur Ethernet SMSC LAN9730 USB 2.0 to 10/100
-
Apple 338S00057 (Numéro de pièce similaire au contrôleur de mémoire personnalisé 338S00055 trouvé dans le Retina MacBook 2015)
-
DP2700A1
-
Texas Instruments PA61
-
Semiconducteur Fairchild DF25AU 010D 030D
Is it possible the Apple 338S00057 is a power management IC? The NAND flash controller is typically integrated into the SoC, and the parts surrounding the 338S00057 look like chokes or inductors.
I would agree with you. The caps/inductors completely surrounding that smell a lot like a PMIC.
The DP2700A1 has a Marvell logo on it. Any guesses to what this is?
Since the SMSC USB to 10/100 Ethernet has an integrated PHY, I'm guessing this is an HDMI interface IC (Either a level shifter, cable driver/ equalizer, or ESD/port protection). Maybe a Maxim part?
It's MegaChips, not Marvell. Looks to be from their range of DisplayPort converters. Probably an eDP to HDMI 1.4 converter. Doesn't appear to be the full blown MCDP2800 DP 1.2a to HDMI 2.0 LSPCON ( http://www.megachips.us/products/documen... )
So the 2800 definitely has 4K support, I couldn´t find any spec on DP2700A1 so we don´t know about that...Could this be an Apple specific version? It shouldn´t be too hard to buy with this with a purchase volume of 10 - 30 million...It seems that this chip has the definite answer to if 4K is possible on the hardware...
Why only 10/100 ethernet and not Gigabit ethernet? I would think anyone considering buying this would think it is easily worth the extra few cents. 4k video requires 15 - 32 Mbps depending on quality, so why not use Gigabit to give more headroom on the bandwidth?
3-6 times headroom isn't enough? Seeing as though the majority of users will be streaming from the Internet, and the majority of those users don't even have 100Mbps or higher connections.
Hi all,
Does anyone know where I can get a replacement board? My apple TV won’t turn on, I removed the board and I have 12v flowing to the board. When I then re-insert the board, the power supply drops dramatically, assuming there is a short to earth somewhere on the board.
Thanks

Plus du puces sur le dessus de notre carte mère :
-
Flash NAND de 32 Go SK Hynix H2JTEG8VD1BMR
-
NXP 1112 0206 5271B4K
-
V301 F 57K C6XF G4
Looks like there is room for a second 32 GB Nand Flash.
It would be interesting to Ohm out the connection to the HDMI connector to see if it connects directly to the A8 CPU, or if it is possibly connecting to the 338S00057 chip. This would tell us if the A8 has HDMI built in, or if Apple is using a 2nd chip to create HDMI from some other signal like LVDS or Lightning serial.
Looking closer, it seems obvious that the DP2700A1 chip has the HDMI traces connected to it, so this is apparently some kind of HDMI transmitter? Does anyone know who makes this chip? It has a large M on the chip, which may be a clue to the manufacturer.
The big question here is if this chip has 4K capability (without current SW support from Apple)?
Link to the flash datasheet is broken. I did a ton of Googling and could not find a link to the chip's detailed datasheet. Strangely, what SKHyinx calls a "databook" is just a list of part numbers with basic capacity and format specs and no other detailed information.
Is the little chip on the front an IR emitter?
Looks like it to me, got two glass bubbles I'd expect to see

Le dernier à sortir de la boîte : un grand dissipateur thermique bien épais avec une jolie petite carte d'alimentation repliée à l'intérieur.
-
L'alimentation redessinée est évaluée à 12 V à 0,917 A. Comparez cela avec le l'alimentation principale de la Apple TV 3ème génération, qui pompe 3,4 V à 1,75 A.
-
Nous avons remarqué un manque distinct de nappes reliant l'alimentation à la carte mère. Nous en déduisons que le courant est transmis soit par magie, soit via les supports des vis du dissipateur thermique .
Heat doesn't rise. Heated fluids rise because of their decrease in density relative to cooler fluid.
But heated air rises...
So on earth—unless you are in a vacuum—heat rises.
On the second picture showing the innards of the power supply, it looks like on the top left the bare screw delivers the power (you can see there's a PCB tracing coming off the cap to it) and the black screws are either for mounting or chassis return.
And looking at the heat sink, some of the posts appear to make contact with the metal rings around the through holes where they would line up, indicating the heat sink's use as a ground plane.
I have to admit, this is creative engineering.
Yes, it looks like power goes through the silver screw at the top, and another screw that is hidden under the power supply clip? You can see on the circuit board where the screw has made physical contact.
Plase expand about power supply. I need to know if it's multi-voltage. I Live in Chile, a friend is travelling to US and I want him to buy an Apple TV. Here in Chile we use 220V 60Hz.
Edison - if you zoom in on the 3rd photo in step 6 there's printing on the board that says "100-240V, 50-60Hz"
It's disappointing that Apple's tech info doesn't state that, or the power consumption, but practically every electronic device now can accommodate either 120 or 240 VAC.
You say "The redesigned power supply is rated at 12V at 0.917A. Compare that to the 3rd-gen Apple TV's main reactor, which pumped out 3.4V at 1.75A."
What you didn't say is: "The 3rd generation Apple TV consumed 5W of power, while the 4th generation consumes over twice as much at 11W."
The way you stated it sounds like maybe you were trying to spin it.
Where can I get a replacement power supply?
Are the power supply separated so I can connect 12 VDC to in instead Lv 230 VAC?

Voici la nouvelle télécommande Siri ! Dotée de doubles microphones, d'une surface tactile en verre et d'un connecteur de charge Lightning, cette télécommande est certainement un peu plus complexe que la télécommande Apple Remote d'antan.
-
Apple y a également inclus un accéléromètre et un gyroscope, qu'ils espèrent que vous utiliserez pour jouer à des jeux et naviguer sur Airbnb.
-
Grâce à Bluetooth 4.0, la nouvelle télécommande n'a pas besoin d'être pointée directement sur votre téléviseur.
-
Enfin, sauf si si vous voulez contrôler votre télé actuelle. Apple souligne que la télécommande pour la nouvelle télé Apple TV peut également contrôler un téléviseur ou un récepteur A/V.
Doesn't the ATV control the TV via HDMI? I don't think Apple uses infrared, so you shouldn't need to be in the line of sight as mentioned in the article.
Correct me if I'm wrong.
You're wrong, partly. The remote uses infrared for volume control on the TV, Bluetooth to talk to the Apple TV and CEC via HDMI for everything else.
Thanks for your detailed info!
Why would they use infrared for the TV volume only? That's, like, THE most basic of all HDMI-CEC commands! Not to mention that making it a programmable IR remote adds a whole other level of complexity to initial setup. Is it conceivable that the IR transmitter has some other purpose?
To adjust the volume on a connected stereo system as well. (...and it works, too.)

Nous avons trouvé où Apple cachait tout l'adhésif ! On dirait que notre iOpener et notre médiator ont choisi ne pas prendre de jour de congé après tout.
-
La partie supérieure de la télécommande n'est qu'un bouton géant. En dessous, une ouverture nous donne un point de départ agréable et cohérent.
-
"Hé, Siri—dis Ahhhh."
-
Si seulement c'était aussi simple ... En fait, c'est vraiment simple. Il semble qu'il y ait une première à tout !
Don’t pick apart from the top end of the remote as the instructions say. There are two dogs that click in and could be sheared off/ broken if you are not careful. Pick from the bottom end near the Lightning port. (like the pictures) (the worded instructions should reflect this)

Tout à coup, l'iPhone 5s nous revient à l'esprit. La moitié supérieure est reliée par une nappe cachée au milieu de l'appareil.

Notre expert en EOD interne travaille avec un spudger et désarme soigneusement le piège.

Le haut et le bas une fois séparés, nous remarquons un motif caché de yin yang. C'est tellement zen de votre part, Apple.
Ying-yang sing? I can't see it...
I managed to get the ribbon cable back in as follows: first, make sure the locking clasp is raised (Open). Next, locate a pair of thin tweezers; I used my wife’s eyebrow tweezers. Hold the upper surface so the ribbon end is lined up with the connector; note that the cable slides into the connector on the opposite side of the connector from the locking clasp. Then grasp the cable with the tweezers and force it into the connector. When it’s properly seated it will have moved about 2 millimetres in. Then, without moving anything, slide a spudger (although anything flat and broad will do, I’ve also done this once with the end of a butter knife) in and close the clasp. Finally move the two pieces apart to test that the connector has seated and locked.
My kid got a couple of the top buttons sticky, and after multiple rounds of cleaning as best I could around the buttons, nothing’s working. Still sticky.
After tearing down the remote carefully, as instructed above, are there any issues with glue missing, after putting everything back together? Did you have to replace the glue? Or is it not really necessary?
I’m actually sending this unit off to my mom, who’s a jeweler, so she’s used to working with small stuff. Just want to have some good information on the best way to break it down, clean it, and put it back together. I’m guessing high-percentage (91%+) isopropyl alcohol is the best way?
Thanks!
Everything works on my Siri Remote, except it stopped recognizing swiping motions on the touch pad last week. Clicking works. Since it was 10 days out of warranty AppleCare said to buy a new one for $59!
Anyone repaired this problem before? Where can I get the part?

OICURAQT – C'est ce que nous disons chaque fois que nous identifions un IC, comme ceux de cette carte mère :
-

Chargeur de batterie et TI 49C37GI Texas Instruments BQ24250C
I think the DSP link is wrong - TI think that the 320 is a C6000 series, not a C5000 series.
It's pretty %#*@ amazing that this remote control has more CPU power that a mid-90s PC (although I'm sure it mostly runs in a deep sleep state).
Ah, nope, TI are just trying to upsell me I think. A better link is http://www.ti.com/lsds/ti/processors/dsp...
Only a gyro is very unlikely, where is the accelerometer? Who can find it? Seems that INVN accel+gyro is not in it
Is there an IR LED? If so, does anyone know the frequency output?

Regardez-moi ça ! Un câble de port de charge Lightning fixé par ZIF.
-
Si Apple peut emballer un connecteur ZIF dans une petite télécommande comme celle-ci, pourquoi le port de charge Lightning de l'iPad est-il soudé à la carte mère ?
-
Réponse : seul Apple le sait.
-
Juste un peu de colle à enlever d'un coup de médiator, et le câble Lightning/la batterie s'enlève en en une seconde.
-
-
-
Une fois l'ensemble port de charge Lightning/batterie hors de la télécommande, nous voyons que la batterie est soudée au port Lightning.
-
Même si nous n'avons jamais été fan des batteries soudées, au moins, un port Lightning, ça ne se soude pas à la carte mère !
-
Étant donné que cette batterie de 410 mAh est rechargeable, vous ne risquerez jamais de partir à la recherche de piles pour votre téléviseur. Merci, Apple !
-
Du moins tant qu'elle ne meure et que vous ne deviez la remplacer.
My battery has died, just after the warranty expired. What are my chances of a replacement?

-
Score de réparabilité de l'Apple TV (4ème génération) : 8 sur 10 (10 étant le plus facile à réparer).
-
La construction modulaire et la présence de seulement quelques composants majeurs simplifient la réparation.
-
L'alimentation électrique est un composant séparé, remplaçable, et même sa prise de courant est modulaire.
-
Des vis Torx standard utilisées partout, rien de propriétaire.
-
La télécommande est maintenue avec de l'adhésif, mais une large ouverture la rend facile à décoller.
-
La batterie de la télécommande et le câble Lightning sont soudés ensemble, mais pas à autre chose, donc ils devraient être un élément peu coûteux à remplacer.
-
Tout ce qui est important est soudé à la carte mère, ce qui signifie qu'il est nécessaire de la remplacer ou de microsouder pour résoudre les problèmes de port.
-
Voilà ! À une prochaine pour un démontage d'iPhone. Bonne journée à tous!
Your video doesn’t show how to put the remote back together. Every time I try to click it back together the track pad no longer clicks. Please help.

Geekbench shows all the Apple TV's at 1GHz apart from an outlier at 1.5GHz
http://browser.primatelabs.com/geekbench...
That suggests it's running at 1.5GHz...
name99 -
The 1.5 GHz one was recorded in 09. The heatsink is probably only there because there's a big AC-DC transformer on top of the apple tv. Odds are it's clocked in a similar fashion to the A8 in the iPad Mini 4
Looks like a different design group worked on this. If it were Jonathan Ive's work it would have that iMac method of carving the case out of a chunk of aluminum and welding it shut with adhesive throughout.
Funny though - here's a device that is easy to get into, but one really doesn't need to whereas the iMac is something one might want to upgrade, but can't get into easily.
@name99 The 1.5 gHz geekbench benchmark is actually on an overclocked first generation Apple TV, back in 2009.
Would it really kill Apple to give us a TV with a 4TB hard disk? Can't do very much with 32GB. At that size, it's no more practical than keeping your videos on a phone.
The storage isn't for movies, it's for apps.
Remember this is a streaming device, not a storage device.
Although I do agree I wish Apple offered a cheap media centre type device.
(Home Sharing from your Mac works, but does have some limitations)
scott -
It is not for the apps. They have 200 MB limit. They will be able to download more when needed.
But that's funny. I can have couple of big games on my 16 GB iPhone so why not on the 32 GB Apple TV. Do they really think that Apple TV owners want to store music or movies on the device now on the 2015?
Does anyone know if the new AppleTV can be controlled via IR like previous generations? I know it's not ideal, but this is often needed when one is tucked away in the rack of a distributed video system.
yes. the old apple TV remotes work on this one still
ralph -
Is the power supply replaceable like it is on the 3rd gen? I am wanting to replace the 110v AC with 12v DC so I can install it in my car.
So where is the IR sensor/receiver on this? I can't quite identify it on the tear down, and I'm pretty sure I've got my IR emitter in not quite the right place.
Thanks!
Mark,
Did you get an answer on this?
I need to know the location too!!
GSM
What is the 49C37GI? PMIC?
Where is the Bluetooth IC in the Apple TV logic board?
Hi, where can I buy Glass Touch surface for apple tv 4 remote control?
Can you comment on where the antennae are located?
Hi
I could teardown my remote to clean it (some clumsy guy put beer on it during a party), but when I try to put it back together, I can’t get the side clicks of the touch surface to work correctly. Just as if it wouldn’t be aligned, though it is :/
Someone had that issue ?
I have my Apple remote taken apart and I cannot get the flex cable back in how do I do it?there is no instructions that actually show the way that it gets put into the logic board
my Apple TV 4 doesn’t power on, is there a way to fix power supply ?
I want to buy touchpad along with tools for my apple remote as mine is broken , can you assist me to find parts?
Is there a special application technique or type of glue to reattach the cover of the Apple remote 4gen “A1513” body?
I left my remote plugged into charge in March (covid) and returned 9 months later to find the cover separated from the body.
The bottom heatsink in step 7 with the power supply board will not come out. Is it glued to the bottom?
Good morning
I have problems with logic board
