This teardown illustrates how to deconstruct the HP MR Headset (DE). This teardown also identifies some of the components within the HMD, and is open to any edits or suggestions for unidentified elements.

This teardown is not a repair guide. To repair your HP Windows Mixed Reality Headset Developer Edition, use our service manual.

  2. Remove the foam protector from the velcro-type adhesive strip.
    • Remove the foam protector from the velcro-type adhesive strip.

    • Remove the two eye-rings with a flat head screwdriver.

    • Also with a flat head screwdriver, carefully pry apart the outer plastic shell from the HMD

    • To remove the next layer of protective plastic, you'll need to remove 16 screws

      • 1 on each side

      • and 14 on the front

    • Now that the screws are removed, the next plastic layer can be removed.

    • The cable will still be connected to the adjustable head strap. This can be removed easily by prying it off with a flathead screwdriver

    • In the bottom left corner of the HMD, you'll find the audio jack and the board attached to it.

    • With a flat head screwdriver, gently pry the connector from the headphone jack board. Once the board has been disconnected, it will fall right out.

    • Remove four more screws. The bottom left screw will release the audio board support.

    • Peel back the lenses at a 45° angle from the bottom up.

    • You'll then see two yellow strips held with black protective tape. Peel back the tape with tweezers.

    • Also with tweezers, remove the yellow tape over the connection between the PCB and the lenses.

    • The lenses appear to be fresnel on the inside but smooth on the outside.

    • With the lenses removed, you can begin separating the PCB from whats left of the HMD.

    • USE TWEEZERS to peel back the two pieces of metallic tape on the PCB (this tape is SHARP — do not use your hands).

    • Remove the four screws to remove the two metal clips on each side of the PCB.

    • After removed the PCB, you can see the front camera sensor compartment.

    • Peel off the copper tape on both side before the next step. (SHARP EDGES -TWEEZERS recommend).

    • Remove 4 screws to disassemble the front camera sensor on each side.

    • Cameras were not easily identifiable, however, they looked identical to the cameras we found in our Acer MR HMD teardown. Also had similar part numbers to the the Microsoft Surface 3 rear camera.

    • The metal cover to the PCB can be easily pried apart with a flat head screwdriver.

    • After doing this, the two screws connecting the cable to the PCB is revealed.

    • Remove the two screws, then pop off the connector straight up, not at an angle.

  4. A little disappointed you didn’t spend more time identifying more of the other components like they HDMI to MIPI controller (not a Toshiba component) as well as the as the processor chip used to handle the two cameras that make up the parallax based inside/out positional tracking. But I have not checked out your Acer tear-down, so you might have done that it already.

    Actually I done my own tear down and you have incorrectly stated the purpose of the Cypress CYUSB3064-BZXC by just identifying its title. This is actually the MIPI controller for the two LCD panels.

    • The main cable is a USB and HDMI to a proprietary connector.

    • Instead of plugging directly into the HMD, the proprietary connector plugs into a receptacle which is attached to an embedded connector (shown on the PCB in steps nine and ten).

    • After finding an active cable module within the Acer headset, we were curious as to why the HP headset had no chips on their cable. So we opened up the proprietary connector on the cable (Do not do this. You won't be able to easily put it back together)

    • Under the plastic shell, we found a similar Spectra7 cable module similar to that of the Acer Windows HMD

      • Spectra7 VR8050 USB 3.0 Cable Equalizer

      • Spectra7 HT8181 HDMI 2.0 Cable Equalizer

This is fantastic thank you! Any plans on tearing down the other four MR headsets from Microsoft?

Hi there,

I am wondering if anyone knows the components I have highlighted.




My HP WMR unit had a power surge and has burnt out most of these components.

A good electrical engineer friend of mine has cast a close eye over all the other components on the board, showing no physical damage (which I know doesn’t mean that they all ok).

I live in hope that I will be able to repair my WMR headset, as I have myself had plenty of experience with SM components.

Just identifying the values of these components is proving to be mighty tricky!

I believe (A) 6 pin “EDVGA” are voltage regulators - SOT23-6?

(B) Transistor? - “NA ID9” ?

Appreciate any help :)

Any info on the sensor in the center mounted between the lenses?

Frank McCown - Reply

From what i’ve seen on other headsets it’s a light sensor ..

controls brightness during light bleed.

Hi. My cameras stopped working, and I think it's because of the USB cable damage.

Do usb3. 0 sstx ssrx lines conduct current when there's no power on hdmi & USB equalizers? I'm sticking one probe of the multimeter to the USB's sstx and the other one to every pin of the combined HDMI-USB plug.

USB 2.0's lines conduct current just fine, but usb 3's line are quiet.

Can you finish this tear down by removing the screens completely.?
