I am having a problem with HDMI upconversion and with getting sound through my TV speakers. First, the HDMI upconversion works going from composite to HDMI but when I want to go from component to HDMI i get nothing, I don't know what is going on? Also I set it to the setting where in the manual it says to lower the volume on the receiver and the volume will come out of the Tv, when i do that it also doesn't work. What am I doing wrong? Thank you.
