拆解

简介

自从我们上一次见到新的Apple TV以来，已经过去了两年。 今天在我们的拆卸桌上，我们有一个直接从Cupertino的技术果园“采摘”的闪亮的新Apple TV 4K。 那么我们该怎么处理苹果的第一台4K HDR流媒体设备呢？狂追《怪奇物语》（Stranger Things）么？ 我们绝对有在想...但是，我们正在拆解这个***的东西！

你想看看我们还有什么吗？

    • 我们都知道这个小黑色方尖碑里面包装正一些“庄重”的4K小方块，但让我们看看这个改版的苹果电视还有什么新的东西：

    • 64位Apple A10X Fusion 芯片

    • 千兆以太网，802.11ac Wi-Fi，蓝牙5.0，红外接收器 和HDMI 2.0a

    • ...还有遥控器：

    • 玻璃触控表面

    • 双麦克风

    • 加速度计和陀螺仪

    • 蓝牙4.0，红外发射器，Lightning 连接器

    • 我们很高兴从我们最喜爱的Cupertino UFO住宅科技公司挖掘出新的电视产品——但首先，我们将要把之前的Apple TV与Apple TV 4k进行比较。

    • 这一次，最新的Apple TV并没有超越其前身，但是我们确实注意到设计中有两个关键的区别。

    • 底板已被重新设计，那些开口看起来像一些散热孔。

    • 再见，USB-C 接口。

    • 在我们打开盒子之前，我们的合作伙伴Creative Electron提供了一些精美的X射线扫描图像。

    • X射线图像显示出了一个新的圆形物体，似乎与底部面板上的新排气口紧密配合。

    • 是风扇？ 还是粒子加速器？ 抑或是接触圈的一部分？

    • 好的，我们的兴趣被激起来了。 是时候打开这个黑盒子看看这个4K升级是什么了。

    • 我们在Apple TV 4K的下侧找到了一条熟悉的通道。

    • 就像其“单K”兄弟一样，Apple TV 4K具有可修复的塑料卡扣，可以固定其底板。

    • 这些卡扣比我们以前看过的更加固执，但仍然不是很难。

    • 没有胶水或不常见的螺丝？ 该升级单元获得1 Up作为奖励。

    • 剥离后面板后显示了一个由一些Torx螺丝固定的坚固的风扇。

    • 拆出T7 Torx螺丝后，我们遇到了Apple TV最大的风扇！

    • 看起来苹果将新款风扇与第四代Apple TV第的散热器/ EMI屏蔽整合在了一起，形成了一个冷却解决方案。

    • 该热电装置的Voltron表明，热输出伴随着4K HDR功能的加入显着增加。

    • 随着更多Torx螺丝扭下，组件被拆卸下来 - 露出由Nidec无刷电机驱动的可更换风扇。

    • 可替换的风扇是拥有者的好消息。 否则，我们猜测一个坏掉的风扇会很快变成一个坏掉的设备。

    • 这个新的风扇组件被一个明显的标识盘保护。 TRON，是你吗？

    Any clue on which way the air flows through the fan unit front to back, back to front or side to side

    Dan - 回复

    From the housing of the fan, it looks like air is pulled in from the front and side vents, then exhausted through the back vents.

    Andy Tran -

    do all modern gadgets have blue loctite tipped screws? i’ve noticed this when i did my apple 4k disassembly, and likewise in replacement screws for my mbair 11inch

    carterschonwald - 回复

    Anyone have any idea where one could find this replacement fan? Mine died and when watching anything 4K or higher (Dolby Vision) it begins to hiccup and lock up after 5 minutes. Took it apart and the fan has seized.

    • 我们很高兴看到，苹果在Apple TV 4K上恪守了逻辑板可被轻松取下的传统。

    • 苹果/Apple 343S00198 64位A10X Fusion处理器

    • 博通/Broadcom BCM57762千兆以太网控制器

    • SK海力士/SK Hynix H9HCNNNBRUMLQR 2 GB LPDDR4 RAM和SK Hynix H9HCNNN8KUMLQR 1 GB LPDDR4 RAM，总共3 GB

    • 苹果/Apple 343S00150（与2015款 Retina MacBook 中的 338S00055 定制内存控制器的部件号相似）

    • 村田/Mutara 339S00381 Wi-Fi /蓝牙模块

    • 东芝/Toshiba THGBX6G8D2LLDXG 32GB闪存

    • Megachips MCDP2920A4 DisplayPort 1.4至HDMI 2.0转换器

    翻译

    Broadcom BCM57762 should be PCIe Ethernet controller.

    JJ Wu - 回复

    Yep, 10/100/1000BASE-T Ethernet PCIe Controller with ASF2.0.

    “The device combines a triple-speed IEEE 802.3-compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, x1 PCIe bus interface and on-chip buffer memory in a single device. The device is fabricated in 1.2V CMOS process, providing a low-power system solution.”

    repoman27 - 回复

    From the components around Apple 343S00150, Apple 343S00150 could be the PMIC. Memory controller should be integrated in the Apple A10X processor. There is 343S00151-A0 next to Apple 343S00150. Supposedly, Apple 343S00150-A0 and Apple 343S00151-A0 could be the PMIC for Apple TV 4K.

    JJ Wu - 回复

    Does anyone know why Apple would use DisplayPort internally and convert it to HDMI instead of just using HDMI internally? (an ELI5 type answer would be best - https://www.reddit.com/r/explainlikeimfi... for more info)

    Matthew Adams - 回复

    What is the exact part number or reference of that motherboard ?

    Can they be purchased on ebay, Apple or anywhere else ?

    Thank You

    Karine-Johanne - 回复

    I’m wondering if you can simply buy the low capacity flash memory AppleTV model (with the 32GB Toshiba THGBX6G8D2LLDXG), then inexpensively replace the chip with a 256GB Toshiba THGAF8T1T83BAIR chip (or similar)?

    Steve Arkwright - 回复

    FYI - The Ethernet Port has a hidden Lightning port inside! If you look inwards you can see the socket hole.

    The back row of contacts on the logic board are the Lighting port connections.

    Dan - 回复

    This may sound a bit crazy, but I’m trying to see if I can power up the ATV4K’s logic board with a 12v Power Bank. I plan on connecting the leads to the Power Posts on the board which according to your specs draws 12v @ 1.083A. Do you see this as doable?

    Mario Choy - 回复

    This is old but for anyone reading, you can definitely power all current Apple TV motherboards with various power supplies. As long as you confirm you are using a properly rated one it will work though if it is out of its housing you lose the heat sinks/fan. (Running Apple TV just fine from bench supply)

    Can i disable bluetooth from my apple tv?

    Seems possible in some way to remove the Murata 339S00381 Wi-Fi/Bluetooth Module and i dont mind the module getting destroyed :)

    I get headache from bluetooth and the aluminium IR controller from the old apple tv works perfectly :)

    Aurin R - 回复

    Would be really interessting for me too. The box could still be used over IR with a ONE for ALL remore IR control.

    My father is also very sensitive to bluetooth.

    I was not able to find productsheets for the Murata Chip, because it's a custom one. Will the box still startup without the chip?

    I would be happy for help!

    • 我们不会在这里遇到任何惊喜；散热片与2015款大致相同。

    • 我们花一点时间从散热器中抽出一对熟悉的电源。

    • 在我们的第四代 Apple TV 拆解期间，我们怀疑电源通过散热器螺丝钉传输到逻辑板。Apple TV 4K看起来还是这样。

    • 随着散热片和柱子的拆下，唯一剩下要做的就是拆下电源板。

    on my apple 4k, theres 4 copper pins on the plate, near the memory controller area (to power the fan?), and theres a slight elevated surface to kiss the CPU and mem controller,

    • 新电源的额定值为12V，1.083A。与第四代Apple TV 的0.917 A电源相比有一个微小的提升。

    • Apple TV 4K避免使用电源和逻辑板之间的内部接线，与从其较旧的兄弟姐妹相比有着更先进的设计。

    • 使用导电柱代替布线可能会节省内部空间，避免了组装过程中夹紧或弯曲的可能性。

    11. 最后的想法
    • 塑料卡扣将外壳固定在一起以方便开启。
    • 模块化部件易于拆卸和维修。
    • 电源是模块化的，并具有可拆卸的交流电插孔。
    • 标准Torx螺丝固定着所有东西
    • 所有主要组件都被焊接到逻辑板上，这意味着固定任何端口问题将需要主板级焊接或全板更换。

Just sanity checking what my eyes are telling me - are both the inner and outer rings of that moving fan parts, or is the outer ring just an air channel?

Edit: ok the last breakdown picture shows the outside is not part of the fan

tipoo - 回复

Got off the phone with Apple. No USB means a corrupted firmware means you will have to send in the device for recovery/restore. You will at least have to pay shipping. Apple stores should be able to recover/restore as well. Don’t exactly the USB pads on the PCB. Maybe the four pads on the left of the bottom image. Anyone?

Kemal NottaTurk - 回复

Maybe they'll allow it to be done through the ethernet port….

Andrew spoelstra -

I just had this happen with the 12.4.1 update. Blinky LED & no video out at all. The bad news is the Genius Bar / Store Techs have no more access to do a factory restore than the user does. IOW: none. Nothing on Ethernet either. (That was straight from the GB guy’s mouth.) If there are USB pads on the board they don’t know about them.

And if this happens out of warranty it’s a $150 board swap. I advise turning off the auto-install for OS updates.

Michael Cashwell -

My Apple TV died, and they Apple store could not do anything to recover it. And Apple does not repair them, so the offered to sell me a new one at full price. And no shop will service them since Apple considers these disposable and does not provide schematics or parts to repair partners, so no one will touch it. They could at least sell logic boards, but you know, Apple I guess is not profitable enough as it is.

Tim Burke -

Any more detailed info (part numbers) on the remote?

techno_freak - 回复

Isn’t that Broadcom ethernet chip used in thunderbolt dongles, but not necessarily anything to do with Thunderbolt? I.e TB carries it, but it's it’s own thing. Not sure this shows Thunderbolt on ARM.

tipoo - 回复

It was so funny, to see it’s and it’s, the first meaning it is, the second meaning its. I haven’t seen that blunder in a long while. Thanks for the laugh.

Roberto Manuel -

That’s a lot of mirth derived from an extra apostrophe. Small things, as they say…

tipoo -

What quick video tear down for a product that took two years to make!

I would go slower and show the chips and defiantly try not to damage the backcover…

Benjamin Nabulsi - 回复

Hm, I wonder if going down to 3GB impacts the A10X 128 bit memory bus from the 4GB iPads.

tipoo - 回复

AppleTV 4K is awesome, seeing it naked it quite sexy indeed. Nice big cool fan.

Riccardo - 回复

Is a bit of an illusion and I had to double check - only the inner blades are a fan, looks about as big as a regular laptops fan. The outer ring is metal air baffles/channels, connected to the upper heatsink, just to bring air in part of the fan and let it push air out the rear part.

tipoo -

When the Apple TV has better cooling than the MacBooks.

Christian Galvez - 回复

What about the possibility to upgrade the 32/64 Gb memory?

Fedele Boccasini - 回复

I wondered the same thing — if you can simply buy the low capacity flash memory AppleTV model (with the 32GB Toshiba THGBX6G8D2LLDXG), then inexpensively replace the chip with a 256GB Toshiba THGAF8T1T83BAIR chip (or similar)?

Steve Arkwright -

Is the memory bus still 128 bit, with 1GB removed from the iPad A10X?

tipoo - 回复

Where is the IR receiver? I can’t see it in the photos.

ggilley - 回复

It uses bluetooth. Only IR is used for the TV.

David Maitland -

This is what I came here for too.

There is an IR receiver, but it seems to have moved a bit left (facing the Apple TV 4K) from where the previous 4th gen was. I installed a few yesterday and stuck an emitter back on the center and got a bit nervous thinking they changed codes.

Aaron C -

Yes, the IR (Infrared) receiver is at the front left side. It is the four dots at the bottom left of the X-Ray photos in STEP 3.

Daniel Mui - 回复

Is the built-in power supply capable of 110-220vdc? I’m thinking about buying one in the US and taking it with me to Asia where the power is 220v

Derrick - 回复

i wish hacked this 4k tv for install IOS 11.1 on it every body have idea???

because in ipad pro same as!!

please how can edit ios image for install ios on 4k tv this is Revolution in age of smart t.v with one wireless touch pad any thing can do

behnam for - 回复

Will it be hacked so that OS X can be installed? Benchmarking tests show the apple tv 4k is more powerful than a lot of macbooks out there…

Oman Sklavier - 回复

Its an ARM chip, Its not suitable for X86 based software unless it gets some serious redesigns and workarounds.

UpicX -

Where is the IR receiver on the Apple TV 4k?

Michael Teruel - 回复

Is the Wi-Fi wave 2 (ie. MU-MIMO)?

Anthony - 回复

Hi, what is the logic board part number ?

Can it be purchased from ebay or apple ?

Thanks

Karine-Johanne - 回复

would like to see you take apart the remote as the trackpad on mine doesn’t click anymore and I can’t figure out why, even after taking it apart.

pjbourque - 回复

343S00150 seems power management chip.

YKU - 回复

I am wondering if we could enhance the Bluetooth antenna to increase its reach when used as a HomeHub

Fernando Scheps Serra - 回复

There is a hidden lightning port inside the Ethernet port, check out http://9to5mac.com/2019/10/17/Apple-tv-4...

stevesphone - 回复

Yeah! I’m wondering the same.

James Almeida -

How did the Lightning port get missed? Didn’t the 7-9 leads on the board behind the 8 for ethernet catch anyone’s attention?

Ryan Coleman - 回复

Do you have the parts numbers ? I search a original Apple TV 4k case

François Rais - 回复

I’d argue with this repair ability score. While you can take it apart, you can’t get replacement parts, and therefore you can’t repair these, which sucks.

Tim Burke - 回复

I think it would be worth mentioning that the Apple TV 4K that has no ports, can be reset by switching off and on the AppleTV several time in a row. I waited 20s in on and 10s while being off.
