DR.J Professional HI-04 Fan Replacement

Introduction

Use this tutorial to replace a faulty fan in your DR.J Professional HI-04 mini projector.

A fan is what keeps the device from overheating. A broken fan can cause the device to overheat, or to not turn on at all.

Before using this guide, be sure to review the troubleshooting page. Sometimes issues with overheating can be caused by overuse, so restart the device and see if the issue persists.

Before you begin, turn off the device. Make sure the device is cool especially if it has been used recently to avoid burns.
