Before troubleshooting, consider if the issue you’re having is due to a damaged cable, a different source (ex: cable box, Blu-ray etc.), or something else.

1. Check if your TV is powered on
2. Check the cables that connect your device to the TV
3. Check the source input (ex: cable box, Blu-ray etc.) to make sure it is connected correctly
4. Check the power outlets to make sure they’re connected securely and to other connected devices
5. If your device is connected via HDMI, check to make sure resolution is set correctly
6. Test a different source (ex: cable box, Blu-ray etc.)
7. If you have multiple HDMI cables, test each one to make sure they work
8. If none of these steps work, then contact your manufacturer for assistance
