Einleitung

This is a prerequisite-only guide! This guide is part of another procedure and is not meant to be used alone.

Follow this guide to remove the internal assembly of an HTC Vive Focus.

Power down your device before you begin. Be careful not to power on your device while making repairs. If you accidentally power on your device, stop working and power it back off before you resume.

This repair requires breaking the plastic welds that help secure the front cover to the device. If you complete this repair, the gaps between the plastic front cover and side panels will no longer be flush. This damage is permanent but only cosmetic and will not affect the device’s functionality, usability, or operation.

    • Place your device upside-down on your work surface.

    • The facerest cushion is lightly held into place by seven plastic clips.

    • Use your fingers to gently pull the facerest cushion straight off of the facerest to remove it.

  2. dOcqkGT13iM2dVRJ

    • Use a T5 Torx screwdriver to remove the eight 4.5 mm screws securing the facerest.

    • One of the screws will be covered by a tamper-evident sticker. Press the driver through the sticker to remove the screw.

    • Insert an opening pick into the upper-left corner of the facerest.

    • Twist the opening pick to release the plastic clip securing the facerest.

    • Repeat for the upper-right corner.

    • Don't remove the facerest yet. It's still attached by the facerest sensor ribbon cable.

    • Pull the facerest out just enough to access the screws securing the facerest sensor.

    • Don't put any strain on the facerest sensor ribbon cable.

    • During reassembly, make sure the facerest sensor ribbon cable is positioned between the lenses before reinstalling the facerest.

  5. HaceRvZ1N4EXF22Z

    • Use a T5 Torx screwdriver to remove the two 2.4 mm screws securing the facerest sensor to the facerest.
