You don't state what device is connected by HDMI. First, ensure that your HDMI cable is firmly seated in both devices. If you still get the no signal message, try replacing the cable. If you've connected a computer, ensure that the video output is set to a resolution compatible with the TV. If no device works in any HDMI port, please call our Product Support team to arrange for service. Contact information is available via http://www.dynexproducts.com/contactuspage.html.
