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

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。
-
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。
-
这个新的风扇组件被一个明显的标识盘保护。 TRON,是你吗?
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
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。

Megachips MCDP2920A4 DisplayPort 1.4至HDMI 2.0转换器
Agreed error in discription - http://www.av-iq.com/avcat/ctl1642/index...
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.”
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)
What is the exact part number or reference of that motherboard ?
Can they be purchased on ebay, Apple or anywhere else ?
Thank You
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)?
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?

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 :)
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。
-
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。

这就是一切了! 现在要重新组装这东西,讲真要开始追《怪奇物语》(Stranger Things)了...

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?
Maybe they'll allow it to be done through the ethernet port….
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.
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.
Any more detailed info (part numbers) on the remote?
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.
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.
That’s a lot of mirth derived from an extra apostrophe. Small things, as they say…

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…
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.

When the Apple TV has better cooling than the MacBooks.
What about the possibility to upgrade the 32/64 Gb memory?
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)?
It uses bluetooth. Only IR is used for the TV.
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.

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

Where is the IR receiver on the Apple TV 4k?
Hi, what is the logic board part number ?
Can it be purchased from ebay or apple ?
Thanks
I am wondering if we could enhance the Bluetooth antenna to increase its reach when used as a HomeHub
There is a hidden lightning port inside the Ethernet port, check out http://9to5mac.com/2019/10/17/Apple-tv-4...
Yeah! I’m wondering the same.
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?
Do you have the parts numbers ? I search a original Apple TV 4k case
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.
That absolutely does not work for everyone. Me included.
