OMG i desperately need help. Im really starting to lose it here. I bought an Xbox 360 Elite today and hooked it up to my Hitachi 42PD6600. Everything was working as normal with the exception of the Xbox screen showing up black and white instead of colored. I eventualy sorted this by switching the colored cables around that come with the xbox360. Result. Color. NOW i turned off the tv and when i turned it back on it did the APS thing saying it was searching for channels and stuff which was fine. But now there is no sound on ANY of the channels. I checked the mute button, i turned up the volume and all the obvious things. Then i resetted to factory settings after learning how to do it in here a few months ago but still no change. I cant think whats gone wrong and cant think of what else to try. Since the factory reset didnt work im DREADING finding out if its something more serious, i have to get this sorted people. Please help.
