Why is the picture dark on my Insignia NS-32E740A12 LCD TV but the sound is fine?

If your Insignia LCD TV has a dark, poor, or no picture (but the screen is lit) while the sound is good, try switching to another channel to rule out station-specific problems. Ensure that the antenna or cable TV is connected correctly and securely. Adjust the brightness and make sure that the correct picture mode is selected. If you are using an antenna, the digital channel signal may be low, so consider adjusting the antenna or using a highly directional outdoor antenna or set-top antenna with a built-in amplifier. Also, ensure that the video cables are connected securely and try a new set of video cables, as the ones you are using may be bad.
