okay, i just bought my ps3. i had purchased these HDMI cables via amazon.com originally for my HD-direct tv. but i connected the cables to my ps3. when i press "input" on the remote, it recogznizes the HDMI. but i don't get a picture. the screen is just blue. i get a picture using the basic a/v cables that came w/ the console. is there a specific HDMI cables for the ps3? i have the Mitsubishi 57732 tv model. any ideas?
