  2. We're excited to dig into a new TV offering from our favorite UFO-dwelling tech company in Cupertino—but first, let's compare Apples to 4K Apples.
    • We're excited to dig into a new TV offering from our favorite UFO-dwelling tech company in Cupertino—but first, let's compare Apples to 4K Apples.

    • The newest Apple TV doesn't tower over its predecessor this time around, but we did notice a couple of key differences in the design.

      • The bottom panel has been redesigned for what looks like some serious thermal venting.

      • Bye-bye, USB-C port.

    • Before we pop the box open, our partners at Creative Electron provided some fancy X-ray scans.

    • X-ray vision reveals a new circular object which seems to coordinate closely with the new exhaust ports on the bottom panel.

      • Is it a fan? A particle accelerator? A portion of the Contact ring?

      • Alright, our interest is piqued. It's time to crack this black box open and see what this 4K upgrade is all about.

    • We take a familiar access route through the underside of the Apple TV 4K.

    • Just like with its single-K sibling, the Apple TV 4K features repair-friendly plastic clips that secure its bottom panel.

      • These clips are a little more stubborn than what we've seen before—but still, they're not terribly difficult.

      • No moat of glue or uncommon screws? This upgraded unit gets a 1 Up as a reward.

    • Peeling back the rear panel reveals a beefy fan secured by some Torx screws.

    Spread the Fixmas cheer.


    Spread the Fixmas cheer.

    • After pulling out the T7 Torx screws, we meet Apple TV's biggest fan!

    • It looks like Apple merged the new fan with the heat sink/EMI shield assembly from the Apple TV 4th Generation—combining them to form one whopper of a cooling solution.

      • This Voltron of a thermal assembly suggests that 4K HDR capability comes with a significant increase in thermal output.

    • With the twist of a few more Torx screws, the assembly is disassembled—revealing a replaceable fan driven by a Nidec brushless motor.

      • A replaceable fan is good news for owners. Otherwise, we're guessing that a failed fan would quickly mean a failed device.

      • This new fan assembly is apparently secured by an identity disk. TRON, is that you?

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

    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.

    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

    • We're pleased to see that Apple keeps with the tradition of easily removable logic boards for the Apple TV 4K.

      • Apple 343S00198 64-bit A10X Fusion processor

      • Broadcom BCM57762 Gigabit Ethernet Controller

      • SK Hynix H9HCNNNBRUMLQR 2 GB LPDDR4 RAM and SK Hynix H9HCNNN8KUMLQR 1 GB LPDDR4 RAM for a total of 3 GB

      • Apple 343S00150 (similar part number to the 338S00055 custom memory controller found in the Retina MacBook 2015)

      • Murata 339S00381 Wi-Fi/Bluetooth Module

      • Toshiba THGBX6G8D2LLDXG 32 GB flash memory

      • Megachips MCDP2920A4 DisplayPort 1.4 to HDMI 2.0 converter

    Broadcom BCM57762 should be PCIe Ethernet controller.

    JJ Wu - Reply

    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.”

    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.

    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 - for more info)

    Matthew Adams - Reply

    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)?

    • We don't run into any surprises here; the heat sink remains much the same as its predecessor from 2015.

    • We take a moment to pluck a familiar pair of presumed power posts from the body of the heat sink.

      • During our Apple TV 4th Generation Teardown, we suspected that power was transmitted to the logic board via the heat sink screw posts. It looks like this is still the case with Apple TV 4K.

    • With the heatsink and posts out of the way, the only thing left to do is remove the power supply board.

    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,

    • The new power supply is rated for 12 V at 1.083 A. This is a modest bump up from the 0.917 A power supply in the Apple TV 4th Generation.

    • Again taking a design lead from its older sibling, the Apple TV 4K eschews internal wiring between the power supply and logic board.

      • The use of conductive posts in lieu of wiring probably saves internal real estate, and it eliminates the possibility of pinched or bent wires during assembly.

    • There's all the bits! Now to reassemble this thing and binge-watch Stranger Things for real...

    • And special thanks Creative Electron for sending us some sweet X-rays all the way from the other hemisphere!

  4. Final Thoughts
    • Plastic clips hold the case together for easy opening.
    • Modular components make for easy disassembly and repair.
    • The power supply is modular and features a removable AC-in jack.
    • Standard Torx screws hold everything together.
    • All major components are soldered to the logic board, meaning fixing any port problems will require board-level soldering or a full board replacement.
    Repairability Score
    Repairability 8 out of 10
    (10 is easiest to repair)


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

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 - Reply

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

Andrew spoelstra -

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

techno_freak - Reply

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…

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

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

Riccardo - Reply

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)?

Steve Arkwright -

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

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

ggilley - Reply

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 - Reply

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

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…

Hi, what is the logic board part number ?

Can it be purchased from ebay or apple ?

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.
