What to do if my Dynex LED TV has no picture and sound?

If your Dynex LED TV shows no picture and no sound, first, ensure the TV and remote are powered on. Check that the video cables are securely connected. Adjust the contrast and brightness settings. Also, verify the power cord is plugged into a working outlet and the correct video input source is selected. Try another channel to rule out station issues. Confirm the incoming signal is compatible and that the antenna or cable TV is properly connected. Finally, check the closed caption settings, as some TEXT modes can block the screen.
