Anyone have any suggestions to problem i am having with my pwd7 and yamaha rxv450 amp. i had xbox and ps2 component cables plugged into amp and component cable from amp to component board on pwd7. everything was fine until i moved my xbox to other room to play it on other tv and now when i went back to play it on the pwd7 i have found that the colour is not displayed correctly. picture is fine but the green xbox logo on startup is kind of browny/yellowy/green not bright green and anything i play through it is as if something not quite connected properly.reds also look very dull almost brown/orange but blues whites etc are all fine. if i plug component lead from xbox straight to pwd7 colour is fine. i did see the same problem once when i had gamecube plugged thru amp but on swiching everything off and reloading the game picture was back to correct colour. i occasionally disconnect the component lead from back of screen and plug in gamecube direct to screen (gamecube least played and easier to switch at back of screen than back of amp. i tried swapping the ps2 and xbox components round but both are displaying same problem. unplugged amp and tried disconnecting and reconnecting all the component leads but to no avail. i don't have another component lead to test but the component cables from both xbox and ps2 work ok going straight to screen so it is not them. component cable is reasonably cheap one but not old and hasn't been abused. not sure if it is this cable or the amp. amp is only about 5-6 weeks old. not being too clued up on the workings off component the cable from amp to my screen is where i think something is wrong but don't want to start buying new cables just to test. as the problem appears to be with greens and reds is the cable the most obvious fault or could the amp be the problem??
