You may have a bad HDMI cable or you may be experiencing HDMI handshaking issues. Before you open the box, connect the WDTV Live to the digital TV HDMI port and switch it on. Refer to your digital TV manual. Use the remote, go to the setup section. There should be a HDMI port setup. Go into the HDMI port setup, press the remote and let the digital TV lock into the WDTV Live. The digital TV should scan the WDTV Live port and lock into the signal. You should at least get the WDTV Live boot screen.
