Introduction
Use this guide to replace the lamp in a DR.J Professional HI-04 if the device is not displaying an image, or it's displaying a dim or flickering image.
The lamp creates light for the device. A faulty lamp can cause the image to be dim, flicker, or to not display at all. This can be caused by the lamp being past its lifespan or by it being broken.
Before using this guide, be sure to review the troubleshooting page. Sometimes issues with the image can be fixed by restarting the device, which wouldn't require replacing the lamp.
