Hi, thank you for bringing this to our attention. We are sorry to hear that your IdeaPad Slim 3 is no longer displaying on your TV. We recommend first trying a different HDMI cable or adapter, testing another TV or monitor if available, and ensuring your display settings are configured correctly by pressing Windows \+ P and selecting the desired display mode. If the issue persists, we suggest contacting Lenovo Support for further troubleshooting, as your laptop may still be covered under Lenovo's warranty. They can help determine whether the issue is related to software, settings, or hardware. We appreciate your feedback and hope to get you back up and running soon.
