I have just got a Sharp Aquos 37inch full hd tv and with HDMI i cant get a picture or sound at all. the xbox knows that it is plugged in and on the right channel because it boots up(lights on console flash as if its loading up)
It never worked on the last dashboard or the new update one.
I have tryed all the video reset option and my TV is HDCP compitable. it works on my old 32 inch samsung with no problems. i have tryed 3 different HDMI cables and even done a full restore on the console useing a scart cable to see if it fixed with no luck.
Needless to say i would rather not play my xbox in SD quality lol
Hope someone can help
P.S I have a HDMI Arcade edition Xbox
