If your Insignia LED TV has a dark, poor, or no picture, but the sound is good, try these steps: * Try another channel, as the station might have problems. * Ensure the antenna or cable TV is correctly connected. * Adjust the brightness. * Change to a different picture mode. * If using an antenna, check the digital channel signal strength and adjust the antenna, or use a better one with an amplifier if the signal is low. * Make sure the video cables are securely connected. * Try a new set of video cables.
