What to do if my Insignia NS-46E790A12 has a dark picture but good sound?

If your Insignia TV screen is lit but the picture is dark, poor, or nonexistent while the sound is fine, consider these potential solutions: * Try switching to another channel to rule out station-specific issues. * Ensure that your antenna or cable TV connection is secure and correct. * Adjust the brightness settings on your TV. * Select the correct picture mode. * If you're using an antenna, the digital channel signal might be weak. * If the signal strength is low, try adjusting the antenna or using a more powerful antenna with a built-in amplifier. * Make sure the video cables are connected securely to your TV. * The video cables you are using may be bad. Try a new set.
