If you'd like to perform an optical calibration of your DVD player, there are a few things you should consider. First of all, this isn't the kind of operation that's generally done in the home. If you don't know what you're doing, it's very likely that you'll damage instead of fix the DVD player. If you still want to continue, follow these steps.
Instructions
1. Remove any discs that are in the DVD player and move the DVD tray to its extended position. Unplug the DVD player to avoid getting shocked when you perform the optical calibration.
2. Take off the outer casing of the DVD player by removing the screws or sliding the top plate out of the locked position. This should expose the DVD deck and lens of the DVD player.
3. Direct your attention to the mechanism that actually moves the DVD. This is located in the DVD deck and should have a part that resembles a train track. It's the part you need to focus on. You may have to move this mechanism to its extended position in order to see the lens.
4. Study the lens. Make sure your problem isn't as simple as a lens cleaning. It's a good idea to clean the lens thoroughly with isopropyl alcohol before attempting to recalibrate the device.
5. Look under or directly around the lens. There will be a tiny pin and bolt system device that reads the light from the laser. This is the mechanism that needs adjusting.
6. Using caution, adjust the pin slightly in the direction of the lens and then plug in the DVD player. Using a system of trial and error, adjust the pin until the device reads the disc properly. This may take a few attempts to get it right.
