Ok i just got this receiver and everything is hook up properly going truth component cables to my NEC LCD the thing is i have a red line that goes up and a buzz on the sound , by unplugging the green cable ( Y ) everything disappears ( image and sound ) it doesnt affect the others like DVD , XBOX , PS3 etc . I changed cables and and from DVDHD1 to DVDHD2 and nothing no changes , i also might ad the i have Toshiba DVD recorder connected with components and i don't have any problem . I am just a another nob about this i heard that maybe a firmware up date will do the job but the guys at my service provider they even know less than i do .
Does anyone had this issue or have any idea what can be Donne ?

Thanks for your replies

Sounds like a possible ground problem, does the problem go away if you unhook the cable feed from it?

Yes it does .
