Introduction

This guide will provide a basic overview of how to replace the laser assembly in a Sony Handycam DCR-DVD650. If your device seems to be functioning normally but it will not read or write, the issue may be with the laser. Please exercise caution with the lens as it can be easily damaged.

Before trying this repair, we would recommend gently cleaning the lens with a cotton swab and 90+ proof rubbing alcohol, making sure the area is as dust free as possible to avoid scratching the lens. Let it dry completely and test to see if this corrects the issue, the laser may just be out of focus.

There are many small parts that may fall out when executing the steps in this guide, be sure to take your time disassembling and reassembling your device and try to work on a clean, flat surface.

The  hand strap can become a hindrance at times. It's best to begin by unlatching it. On the padded section  of the hand strap, pry up the Velcro and peel out the thin strap sandwiched between them. Push the thin strap through the metal loop at the front of the device.

With the screws removed, the black and silver housing pieces should be able to shift apart from one another. Caution: do not pull the device apart willy-nilly. There is an internal ribbon cable attached to both halves of the housing that can easily be damaged by doing so. Slow and steady wins the race. Gently work the black and silver housing pieces away from one another.

Remove the bronze screw (2 mm, Phillips #00) attaching the  rear housing to the frame. If you are using a screwdriver that uses interchangeable tips, the connecting base of the screwdriver is too wide for reaching this screw. You will need to use a standard (and magnetic, if possible) Phillips #00 screwdriver. Once the screw is removed, the rear housing can be gently pulled away.
