    • At first there didn't seem to be way into this device

    • Flipping the device upside down, there was cover between the enclosure, and the base. Removing this cover revealed sixteen T5 screws

    • Removing the sixteen screws, only removed the base

    • There was still no obvious way into to the product

  4. Facebook Portal TV Teardown: stap 4, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 4, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 4, afbeelding 3 van 3
    • It was time to get the Spudger Tool out and test a few edges

    • Working along the front edge, it appeared that the face plate was glued or held in place with double stick tape

    • The Spudger Tool was use to loosen a gap along the face plate edge

    • A Jimmy Tool was used to further release face plate

    • With the face plate removed

    • we can see the led light pipe

    • we can also see the camera shut off switch

    • LED Light Pipe

  5. Facebook Portal TV Teardown: stap 5, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 5, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 5, afbeelding 3 van 3
    • At this point we close to getting into this device

    • Now we are confronted with eight more T5 Screws

    • Time to get the Spudger Tool out and pry along the face again

    • This face plate houses the camera and speaker

    • With the face plate pulled back, we are confronted with two more T5 screws in the very back of the unit on the left and right of the product

  6. Facebook Portal TV Teardown: stap 6, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 6, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 6, afbeelding 3 van 3
    • We are much closer now to opening up the unit and getting access to the electronics inside

    • As mentioned in the last step, there are two T5 screws in the back of the unit

    • Just when we thought we had all the screws removed, the switch on the side unit is stopping the electronics from being pulled out of the enclosure. It has two T2 screws holding it in place

  7. Facebook Portal TV Teardown: stap 7, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 7, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 7, afbeelding 3 van 3
    • We can now use tweezers to remove the speaker cable attaching the front panel to the rest of the enclosure.

    • Then we can slide out the metal enclosure that holds the electronics from the main enclosure

    • Now use we can use tweezers to flip up the flex cable lock latch to release the flex cable attached to the main electronics in the metal enclosure and outer body. As will be seen shortly, this cable goes to a microphone array PCB in top of the outer enclosure

  8. Facebook Portal TV Teardown: stap 8, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 8, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 8, afbeelding 3 van 3
    • Now with the outer enclosure removed, and the front plate removed we can work on opening up the metal enclosure that contains the main electronics

    • The metal enclosure is held together with eight T5 screws. Use a T5 tool to remove these screws

    • The metal enclosure is also held together on each outer end with a flexible sticker type antenna. These flexible antenna will have to be removed before the metal enclosure can be opened up

  9. Facebook Portal TV Teardown: stap 9, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 9, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 9, afbeelding 3 van 3
    • Unfortunately, removing the flexible antennas will destroy them. Since the antenna are flexible, and have adhesive use to hold them in place. However, It may be possible to remove the antennas and use some adhesive to hold them in place when putting the unit back together

    • Use tweezers to remove the flexible antennas on each end of the metal enclosure

  10. Facebook Portal TV Teardown: stap 10, afbeelding 1 van 2 Facebook Portal TV Teardown: stap 10, afbeelding 2 van 2
    • With the metal enclosure screws removed, and the flexible antennas removed from each side of the metal enclosure, the metal enclosure can be opened to give us the first look at the electronics within

    • We also see that the metal enclosure is not meant for much RF Shielding as much as it is meant for cooling and weighting down the product.

    • The cooling is via a copper heat pipe

  11. Facebook Portal TV Teardown: stap 11, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 11, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 11, afbeelding 3 van 3
    • Now it is a good time to remove the side button flex cable from the bottom side of the unit.

    • This can be done by using tweezers to remove the plastic film over the button connector. Then using tweezers to lift up the connector latch and to pull the button flex cable free

  12. Facebook Portal TV Teardown: stap 12, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 12, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 12, afbeelding 3 van 3
    • Before we can get a closer look at the electronics, we also need to remove the u.fl Antenna cables that attached to the main electronics board

    • A Spudger Tool can be used to pry up and off the Antenna cables from u.fl connectors

    • Now use a Spudger Tool to remove the main electronics board from the metal enclosure

  13. Facebook Portal TV Teardown: stap 13, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 13, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 13, afbeelding 3 van 3
    • With the main electronics board removed, we can now remove the camera that is attached

    • To do this, first remove the plastic film over the camera connector. Then remove camera flex cable by prying up on the connector latch and siding out the camera flex cable free with tweezers

  14. Facebook Portal TV Teardown: stap 14, afbeelding 1 van 1
    • Camera flex cable is also held in place via a thick plastic block attached to the main electronics PCB. This plastic block can be pulled away from the PCB

    • Now that we have the main electronics PCB removed, we turn our attention back to the small electronic PCB locate in the top of the main enclosure

  15. Facebook Portal TV Teardown: stap 15, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 15, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 15, afbeelding 3 van 3
    • As can be seen in the first step photos of this teardown, there are eight pin holes in the top of the main enclosure. These pin holes are for the microphone array. The holes pass sound to the eight MEMS Micrphones below the pin holes

    • On the opposite out side of the main enclosure, we see eight circle holes. These hole are covered on the inside by black tape

  16. Facebook Portal TV Teardown: stap 16, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 16, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 16, afbeelding 3 van 3
    • We can use tweezers to punch a holes in the black tape to give access to the screws that hold the microphone array PCB on the opposite side of the enclosure

    • Once we have holes punched in the tape we use a T2 Tool to remove the screws holding the Microphone PCB in enclosure

  17. Facebook Portal TV Teardown: stap 17, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 17, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 17, afbeelding 3 van 3
    • After the microphone array PCB mounting screws have been removed, we can just Spudger Tool to pry the PCB free. It is also held in place with double stick tape in addition to the screws

    • Once the Microphone Array board has been removed, we can get a closer look at it

  18. Facebook Portal TV Teardown: stap 18, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 18, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 18, afbeelding 3 van 3
    • Now we can turn our attention to separating the camera from the front panel cover

    • Use a Spudger Tool to remove pry up on the metal tab attaching the camera to the front cover

  19. Facebook Portal TV Teardown: stap 19, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 19, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 19, afbeelding 3 van 3
    • Now we can separate the Speaker from the front cover

    • The speaker is held in place with four T2 Screws. Use a T2 Tool to remove these screws

  20. Facebook Portal TV Teardown: stap 20, afbeelding 1 van 3 Facebook Portal TV Teardown: stap 20, afbeelding 2 van 3 Facebook Portal TV Teardown: stap 20, afbeelding 3 van 3
    • Turning our attention back to the main electronics PCB, we need to remove the RF Shielding so we can see components under the RF Shields

    • Use a pick tool to remove each RF Shield. The RF shields are only snapped in place and can be easily removed

  21. Facebook Portal TV Teardown: stap 21, afbeelding 1 van 2 Facebook Portal TV Teardown: stap 21, afbeelding 2 van 2
    • Now flip the main electronics board over and remove two more RF Shields

    • Use a dental pick tool to remove these RF Shields

  22. Facebook Portal TV Teardown: stap 22, afbeelding 1 van 2 Facebook Portal TV Teardown: stap 22, afbeelding 2 van 2
    • With the RF Shielding removed, we can take a closer look at the components on the PCB. The main SoC is underneath the Sk Hynix Memory, and not easy to access. Sk Hynix also makes image processors, so it could be their SoC/Imager. A number of parts could not be crossed referenced, if you have information on a part please leave it in the comments

    • FLH - could not cross reference

    • Now we turn our attention to the microphone array board

    • We can see that one side of the board has ports (holes) for the microphones

    • The other side of the board has the eight MEMs Micophones

    • Infineon IM69D130 MEMS Microphone

I suppose first gen 10 inch FB Portal also has WCN3990 2x2 MIMO antennas?

Anonymous - Antwoord

That's a beautiful processor

Austin Bihlman - Antwoord

Step 5 has a mistake.

I assume the author meant to say, 8 t2 scews (where they said t5) - as the required tool list has a t2 listed… However, my portal tv had 8 t3 screws here, NOT t2!

jack44556677 - Antwoord

What is the voltage and amperage for the power supply? Do you know the diameter of the barrel plug?

Michael Innes - Antwoord

The power supply is 12v DC 2 amps. I too am looking for the barrel connector size. I want to replace the power supply with a POE adapter.

For what it’s worth when I measured the barrel connector in tool used to measure screw sizes it measured 2.78mm (7/64 in). I have no clue what the inner diameter is though.

Any help would be greatly appreciated.

Isaac McDonald -

Anyone ever find the exact barrel measurement? Want to add a 90-degree adapter for flush wall mount.

ariel evnine -

I bought a kit with like 40 different barrel connector adapters and the only one I could get to work was 3.0x1.1, and that was a SUPER tight fit. I had to force it, but it started working. I'd imagine like a 2.9 or 2.8 outer is the actual correct size.

Jacob Hruska (All Might) -

Using vernier calipers, I have measured the power adapter tip, female side:

Depth is 0.393 inches, or 1.00 cm.

Width (diameter) is 0.100 inches, or 0.254 cm.

Uncertainty is ±0.005 inches, or ±0.01 cm
