Ok well I have hooked everything up ( sony ht-ddw995 hdmi, playstation 3, our hdmi cable box and our hd tv) we ave sound but no picture! What did we do wrong! Please help have been working on this all day and feel like just giving up :mad:

Do you have both Play Station and Cable box hooked to HDMI on TV. 2 HDMI inputs?

Have you searched through the various input ports to get picture and sound?

In theory, you should have the cable box HDMI going to you TV's HDMI input port. I have also heard once before that some cable boxes use HDMI to transport Picture to the TV, but not Audio. Look on your cable box to see if they have a fiber optic port or a coaxial audio port to route over to the TV.
