If your Dynex TV screen is dark and there's no sound, try the following: * Press on the TV or the remote control. * Ensure the power cord is plugged in. * Check that the video cables are securely connected to the back of your TV. * Make sure that the correct video input source is selected. * Try another channel to rule out station issues. * Confirm the incoming signal is compatible. * Ensure the antenna or cable TV is correctly and securely connected. * Check the closed caption settings, as some TEXT modes can block the screen. * Adjust the contrast and brightness. * Make sure that the Audio Only option is set to Off.
