ah but it might have taken less time if you said "hum" in your last post, which said, "When i mute the D2v sound and place my ears next to my rear speakers(closest to the unit), i hear significant broadband noise from speaker."
There is a big difference between hum and broadband noise, aka hiss, pink noise, white noise, random noise, and waterfall sound.
Public service announcement: Please always be precise when describing a problem or noise. These are all different but often confused (certainly not singling you out dmusoke):
hiss - there will always be some, but should not be audible from the listening area with average-efficiency speakers
hum - almost always caused by a ground loop, can be caused by bad filter cap in power amp (or bad design) but I haven't seen that since the tube days
buzz - most often caused when there is a ground loop with cable TV connection, at least when I was in tech support. Quick easy test - disconnect cable to see if buzz disappears. It just occurred to me that I haven't heard anyone mention it since the switch to digital cable, no idea whether that amounts to anything. Also caused by faulty ground connection in interconnect. There are other causes but they're relatively rare as far as everyday HT is concerned.
snap, crackle, pop, whine - exactly what each name implies
digital noise - can mean anything, please be more specific
When reporting any of the above please always indicate relative loudness, such as how far from speaker one has ot stand to hear it, the speaker model or efficiency if known, and exactly when noise does and doesn't occur. This could save a ton of time in the end.
