I'm not sure if my new DSM 750 is defective. I can't get the unit to recognize the HDMI output to the television. The HDMI cable works with my DVD player, so I think it's not a cable problem. My LG HD television has 2 HDMI ports and I've tried each one with no signal. I had a Western Digital Media Center connected to the HDMI so I don't think the problem is with the HDMI jack on the television. I can only receive a signal from the DSM 750 when using a component cable. Is there a setting I'm missing? Thanks for any help out there.
