1. Adjust the antenna or cable connection. Ensure the antenna or cable is securely connected to the TV. If using an antenna, try adjusting its position or direction to improve signal strength.
2. Check for interference. Move any electronic devices or appliances near the TV to see if they affect the image. If they do, try moving them farther away from the TV.
3. Update the TV's firmware. Some TVs have firmware updates available that can improve image quality. Check the TV's manual or the manufacturer's website to see if an update is available.
4. Try a different input. If you're using a set-top box or other device, try connecting it directly to the TV to see if that makes a difference.
5. Reset the TV to factory settings. This can sometimes fix image issues. Consult the TV's manual for instructions on resetting it.
If none of these steps work, the problem may be with the TV itself. In that case, you may need to contact the manufacturer for further assistance.
