Why is there no picture and sound on my Dynex LED TV?

If your Dynex LED TV has no picture and no sound, try the following: - Press the power button on the TV or the remote control. - Ensure the power cord is plugged in securely. - Verify the video cables are securely connected to the back of the TV. - Select the correct video input source. - Adjust the contrast and brightness settings. - Try another channel as the station may be experiencing problems. - Confirm the incoming signal is compatible. - Ensure the antenna or cable TV is connected correctly and securely. - Check the closed caption settings, as some TEXT modes can block the screen.
