Why is my Toshiba 43L310U TV screen dark but the sound is good?

If your Toshiba TV displays a dark, poor, or no picture but the sound is good, try changing the channel. Make sure the antenna or cable TV is connected correctly and securely. Adjust the brightness. Press the PIC SIZE button to change the aspect ratio. If using an antenna, adjust it for better signal strength. Check that the video cables are connected correctly and securely. The video cables themselves might be faulty, so try a new set.
