i recently hooked up my Samsung HDTV and a sony bravia 5.1 sound system. Everything was working fine for a few days, then I got this message "the HDMI input is blocked" Does anyone have any idea what the heck is wrong? I unplugged the tv and the sony and then plugged everything back in and everything was fine. I am concerned that the tv is not installed correctly. Any advice would help.
Thanks

Probably just a simple HDMI handshake that went bad. It would be hard to screw up an HDMI connection.
