DR.J Professional HI-04 Speaker Replacement

Difficulty

Moderate

Steps

Time Required

45 minutes - 1 hour

Introduction

Use this tutorial to replace a faulty speaker in your HI-04 mini projector. You might notice distorted sound, or static, or the device won't produce sound at all.

A speaker is a device inside of the projector that produces the sound you hear from the device. You might get a faulty speaker due to damage over time or if the device is physically damaged.

Before using this guide, be sure to review the troubleshooting guide. Sometimes issues with the noise can be fixed by restarting the device, which wouldn't require replacing the speaker.

Tools

Phillips #0 Screwdriver

Step 1

Flip the projector so that the bottom is facing up.
Remove eight 10.0 mm screws from the back case with a Phillips #0 screwdriver.
The screws are set deep in the holes, so be careful not to drop them.
Remove two 20.0 mm screws with a Phillips #0 screwdriver.

Step 2

Flip the projector so it is upright.
Remove the top case of the projector.
The shell of the projector should lift up easily but is fragile, so be gentle while lifting.
The top case is connected to the motherboard by cables, so avoid yanking it off to prevent snapping the connectors or damaging components.

Step 3

Remove the three pieces of tape securing cables.
Keep the tape for reassembly.

Step 4

Use a Phillips #0 screwdriver to remove the four 15.0 mm screws from the motherboard.
Be sure to not drop the screws in the device as they can be difficult to recover.

Step 5

Squeeze the tab against the connector, and pull the connector straight from the socket to disconnect the speaker cable from the port.
The cable should come out easily so do not pull too hard.

Step 6

Use a Phillips #0 screwdriver to remove the three 15.0 mm screws from the black cover.
The screws are set deep in the holes, so be careful to not drop the screws, as they can be difficult to recover.
