I have a SONY STR-DH720 connected to my TV via HDMI out. This receiver claims it can convert Component IN to HDMI out (to TV), but my Xbox 360 will not work. Anyone else had this problem? Anyone have a receiver that successfully connects the Xbox360 via component cables?
Many receivers accept 1080i inputs on component, but do not allow 1080p to be converted to their HDMI output. My pioneer receiver was the same way- until I switched to all HDMI I had to set the xbox output to 1080i via component.
On the Abt website for your receiver I found:
"6 HD Inputs
Get versatile HD connection options with six HD inputs. Four HDMI™ inputs (up to 1080/24p capable) let you connect a Sony® PlayStation® 3 entertainment system, Blu-ray Disc™ player, and any 2 other HDMI-capable devices, for high definition video and audio.6 Two component inputs (1080/60i capable) provide added HD-capable connectivity and versatility. "
HDMI can be a real problem. Monoprice has some converters, see what their reviews say about going from component to hdmi, then feed that to your receiver and you might be ok. It is very device dependent because the HDMI spec is 'loosely' implemented by manufacturers.
To be clear, you have a super-old, original version Xbox 360 that does not support HDMI, right? Try setting component out to 720p, then 480p and see if it starts working for you. I would also check your receiver settings to see if the feature is turned off. That function is normally able to be disabled, and I would not be surprised if it's off by default.
