Can anyone help me to understand why the hdmi signal doesn't work on my new blu-ray player through my lg 22ls4r hdtv.
currently i can only watch DVDs through the video & AV output on the red/yellow/white cables that came with my TV. Therefore the picture quality doesn't appear to be full HD.

Is this a problem with the player, cable or TV. When I turn the blu-ray player on the HDMI output shows the philips screen then when the player loads the picture goes black and get a no signal sign on my TV.

A solution to this would be extremely helpful, and if not a solution at least an understanding of why it keeps happening.
