1 Red Ring on XBOX 360?

[ttldomination]

Hello,

I turned on my friend's XBOX and turns out that he has 1 red ring. For example, the red ring of death has 3 lights on, but this type only has 1 red light on.

I'm trying to figure out what the problem is. Some websites say it's not plugged into the TV and some say that it's a manufacturing issue.

Please let me know if someone here has dealt with this problem, or knows about it.

Thank You.
