Black TV Screen Problem With Elgato HD Game Capture?

Every time I try to use my Elgato HD Game Capture, on my Playstation 3 it shows that the Software of the Elgato HD Game Capture works, but my TV shows a Black Screen, I have tried to search on Youtube to see if there was a Video that could help me, but none have helped me with the issue at hand, I have tried switching the HDMI Cables that are in my TV, I have tried to use other Resolutions 576p, 720p, 1080i, 1080p, none worked, I have tried to use something else instead of a D-Terminal Cable that came with my Elgato HD Game Capture, I tried to use a Speed-Link Cable with de Red, Blue, Green, White Cables together with the Retro Gaming Cable that came along with my Elgato HD Game Capture, I really just want my Elgato HD Game Capture to work, I have spend my own Money in it to get it, I don’t want to see it go to waste, and my TV is a PanaSonic, my TV supports up to 1080p, my Playstation 3 is the Slim Model the one that came after the Original Model of the Playstation Line, any help, and I mean ANY FORM of HELP is very, very, very, VERY, much appreciated.

Welp..
