As the title says, I have an Xbox with an incredibly annoying buzz/hum problem. The buzz comes from the speakers of the TV, not the Xbox itself. And only occurs when using the component cables. When using composite cables, the audio is perfectly fine. Haven't tried SCART as I do not have the cable. I'm pretty sure this issue wasn't an issue just a few months ago. I've tried using different power cables, different power sockets (in case of grounding issue)... I think SOMETIMES it depends on what game is being played whether the buzz appears. My Xbox is softmodded, with the only physical mod being a new SATA HDD using an HDD to SATA adapter. Is this a possible cause? The only other thing I can see are three capacitors that LOOK like they are bulging, but no leaking yet (cannot post links to photo due to lack of posts). The three caps in question are right below the CPU heatsink, labelled C3E2, C2E5 and C1E1. Are these caps related to audio, or are they related to something else like power? So the question is... does anyone out there have any ideas as to the cause of a buzzing noise with component cables that probably wasn't there a few months ago?
