A portable DVD player can gather dust and residue on the playing device inside. When the inner mechanisms are dirty, the laser lens can become damaged. To repair a damaged lens, the player will need to be opened and the lens will have to be replaced. Most portable players with this problem will follow this same process. With a new laser, the player will recognize any discs that are inserted and will be able to operate properly.
Step 1 – Protecting the Player
Lay the piece of soft fabric on a hard, flat surface. Make sure you have ample light to be able to clearly see the inner mechanisms of the device. Close the lid to the portable DVD player and gently lay it upside down on the cloth.
Step 2 – Removing the Battery
There is a screw securing the battery compartment enclosure to the player. Use the Philips screwdriver to remove the screw. Place the screw into the small container. Remove the battery compartment lid and the battery.
Step 3 – Disassembling the Player
Use the flat blade screwdriver to separate the upper and lower parts of the casing of the portable DVD player. Do this by sliding the screwdriver between the two parts and gently forcing them apart. Remove the bottom of the casing and lay it next to the top part. Be sure that no wires become disconnected.
Step 4 – Removing the Laser Unit
Examine the laser unit in the middle of the bottom casing. Gently loosen the laser from the rails that hold it in place. Remove the laser unit and lay it down on the cleaning cloth.
Step 5 - Cleaning the Laser Compartment
Remove the screws from the laser compartment with the Philips screwdriver. Place the screws into the small container. Remove the laser part and put it on the cloth. Use the can of compressed air to blow any dust or residue from the residue. Keep in mind that compressed air can be dangerous and should never be left out where children can get to it. Always keep it out of their reach.
Step 6 – Replacing the Lens
Remove the damaged laser lens from the laser unit. Put the damaged lens into the garbage so as not get it confused with the new lens. Put the replacement laser lens back into the laser unit and secure it with the necessary the screws.
Step 7 - Reassembling the Player
Reconnect the laser to the compartment. Place the laser unit back inside the railings on the bottom part of the player casing. Use the compressed air to remove any dust or residue from the the bottom and top parts of the casing. Put all of the other parts of the portable DVD player back together. Place the battery back into its compartment and secure it with the screw.
