How To Fix a Portable DVD Player Thats Not Reading or Loading Discs
Before cleaning the laser lens, make sure the portable DVD player is turned, as you don't want to clean the laser lens when it is operating, as you may stare into it by accident, which can cause damage to your eyes.
To clean the laser lens, simply eject the disc tray flap remove the disk, the laser lens will then be exposed. Then pour a sensible amount of rubbing alcohol onto one end of the ear bud and clean the lens of the laser, upwards and downward gently. Don't scrub the ear bud onto the laser lens, because it will not clean it better, instead it will make the situation worse because it will cause the lens of the laser to get scratched. Once you have cleaned it, let the rubbing alcohol evaporate for 30 seconds. Then reinsert a DVD movie, does the player now read the disc?
If it doesn't, the laser lens is likely to be burned out, due to wear and tear. So you will need to order a replacement laser lens and replace it with the current laser in the portable DVD player.
