I narrowed it down. If i unplug the HDMI from the 360 and turn it on, green light.
The minute I plug in the HDMI cable, the RROD happens.
Are you also using the AV cable for sound? Because, if you have the HDMI cable unplugged when you turn it on, shouldn't you get a solid red ring around the xbox?
If it is unopened and giving you errors, send it back to MS for a refurb, better than buying a new one (if you don't have the spare cash?)
