Introduction

This guide will inform you on the steps required to remove the motherboard from the Sony Walkman D-EJ360. The motherboard is the central electronic component that interacts with all of the other components on the device. If your device is not powering on, not producing sound, or facing other issues, replacing the motherboard may be a key step in returning functionality to the Sony Walkman. The motherboard is moderately difficult to remove as it requires all non-soldered components to be removed beforehand. The motherboard is a sensitive electronic. The use of an ESD strap is highly recommended.

Insert the metal spudger in the crevice between the blue lid and the white body of the Walkman.
There is a notch where the lid is held under to stay in place. With the spudger, push the blue lid portion down and out.
This may require some harder force. You will hear a popping sound when you successfully push the lid out under the notch.
Repeat the same tactic on the other side. The other side should become easier to pop off.
Remove the lid.
