If your DVD player becomes malfunctioning or stops reading information from the disc, the head of the laser lens may be clogged. Before going to a repair shop, try cleaning it yourself.
Necessary
- - cleaning dvd disc;
- - special liquid for cleaning;
- - aerosol can with compressed air;
- - cotton buds;
- - ethanol;
- - water.
Instructions
Step 1
Read the instructions for your device and find out if you can use a dedicated cleaning disc. Choose which treatment, dry or wet, you will use when cleaning the head. If wet, you will need a special cleaning liquid, which is applied to the disc in the amount of two drops.
Step 2
Insert the cleaning disc with the arrow facing forward into a turntable or drive in your computer. The operating time will be equal to the duration of the playback of a track specially recorded on the disc. A similar disc can be purchased at a specialty store that sells household appliances.
Step 3
Blow off dust from the lens surface using a special aerosol can with compressed purified air. A thin plastic tube extending from the cartridge head allows you to direct the air flow to the desired location.
Step 4
To clean the laser, aim the tube at the lens and blow for two to three seconds. Such cans are sold in specialized stores, their cost is low, and they last for a long time. If you try to remove dust with an ordinary brush, it is unlikely that you will succeed 100%.
Step 5
Clean the lens surface with a cotton swab, the thinner it is, the better. You can make it yourself by taking a match, cutting it off and winding a little cotton wool around the tip. The main thing is not to scratch the surface of the prism and try not to leave any cotton inside the device.
Step 6
Wipe the prism with a few gentle strokes. Then reassemble the laser, aligning the risks correctly. If the contamination is very strong, use ethyl alcohol diluted with water, in a ratio of 1: 1.
Step 7
Do not press hard - this can erase the special anti-reflective layer on the lens surface and damage its mechanism.
