Why do I have sound but no picture on my Visio TV?

If your Vizio TV has sound but no picture, it could be due to several factors. First, check if the TV is set to the correct input source; sometimes, the wrong input can result in audio without video. Additionally, ensure that the connections, such as HDMI or component cables, are secure and not damaged. If the issue persists, it may be a problem with the TV's backlight or display panel, which might require professional repair.
