Been Playing the Xbox 360 Slim on the Sony Bravia TV through the HDMI cable without problems since Xmas 2010.
Last couple days it seemed to be taking a lot longer to come onto screen. Started tonight and TV says "Unsupported Signal. Adjust your PC Output" I get a picture but NO Sound. Tried different HDMI cable, same problem, tried different socket in the TV again, same problem. Even tried changing SKY HD to the Xbox socket and the sky was Fine, HDMI 1 Sky / 4 Xbox changed to Sky 4 / Xbox 1 again with differnet cables. Then change Xbox HDMI cable to Sky HD box and now problems with the picture or sound.
IF, I put the cable in to play on the DVI socket in monitor, again it's very slow to come onto monitor but I do get picture and sound.
Tried to go to settings in the dashboard and go to HDTV but all I have are the resolution settings. From what I remember that used to have HDTV option when you first went into the display screen in settings from the dashboard.
Would this suggest that the OUTPUT sockets for the Xbox or going/gone???
Thanks for any help,
