There are several possible reasons why your DVD player is not playing movies, but is playing CDs. Here are some steps you can take to try to fix the issue:
- Clean the disc: Sometimes, a dirty or scratched disc can cause the "no disc" error message. Try cleaning the disc with a soft, lint-free cloth, wiping from the center outwards. Avoid using harsh chemicals or abrasives.
- Clean the DVD player: A dirty lens or other components in the DVD player can also cause problems with reading discs. Try using a DVD lens cleaning kit to clean the lens, or open up the DVD player and carefully clean any visible dust or debris.
- Check the disc format: Make sure that the movies you are trying to play are in a format that is compatible with your DVD player. Some players may not support certain file types, such as Blu-ray discs or region-specific DVDs.
- Check the connections: Make sure that all cables and connections are securely plugged in and functioning properly. Try using a different cable or port if possible.
- Reset the DVD player: Some DVD players have a reset button or option in the settings menu. Try resetting the player to its default settings and see if that resolves the issue.
If none of these steps work, it's possible that there may be a hardware issue with your DVD player, such as a malfunctioning laser or drive motor. In that case, it may be necessary to take the player to a repair shop or consider purchasing a new one.
