this is a really strange problem, phone support didnt even know the answer, bought a xbox yesterday, plugs it all up to my HDMI tv, blank screen... hmm ! connects it to my neighbours tv, and it worked ! exact same cables / leads ect.., soo.. brings his xbox to my tv, and his worked !! plugs mine back up to mine and it dont ! so i uses to old school xbox lead " composite " or what ever its called, with the red white yellow wires, and it works on that, but obviously graphics are poor, connects my xbox back to his tv using hdmi and it works ! worked on my other mates hdmi tv as well ! just dont work on mine using hdmi ?! while connected to my mates tv, we changed the hdmi settings on the xbox, connects it back to my tv, then it works !!! BUT THE COLORS ARE ALL PINK ?! cant play COD in pink mode.. lol..tried changing resolution , every 1 says 50hz not surported by my tv or something, so im stuck, is it the xbox that has a problem or the tv ?! bare in mind i had a ps3 connected up to the same tv using hdmi and it worked fine... so im a little confused, any 1 have any ideas what so ever? thanks in advanced !
