Query: Appears to be good quality, but doesn't work.

I recently bought a Blu-Ray player and needed an HDMI cable for it. I got this in today, and the TV couldn't pick up the signal. I tried different ports, same problem. So, I switched the HDMI cable from my DVR/TV box to the Blu-Ray player to make sure it wasn't the player - nope, that works fine. The cable is defective and 100% doesn't work at all. It appears to have solid build quality and doesn't appear to have any damage; but that doesn't matter if it doesn't even work.
