Microsoft's Official Position on the XBox 360 3 Red Lights Problem
A search of the Microsoft XBox 360 support website will bring you to the information you see below (current ar of December 2007).
Now understand that depending on your situation, this information may or may not be helpful. Basically what Microsoft is saying is that you should first check your warranty status. If you're covered, great. Ship it back and they will, at their option, repair or replace the X360 unit. It's important to note that even though you'll be without your XBox 360 for the better part of two weeks, it's still worth it to go this route because if you open up the XBox 360 main unit, you automatically void the warranty. If you're out of warranty anyway, however, things aren't quite so simple. Microsoft will still fix it for you, but you pay their repair charge which is currently around $140.
Your other two options are to use a 3rd party repair service, which will cost you around $50-$70 and 7-10 days, or get one of the "Do-it-Yourself" fix-it guides. This website is about the latter option.
Here's Microsoft's official position taken from their website:

Xbox 360: Three red lights flash on the Ring of Light
Article ID : 907534 Last Review : September 15, 2007 Revision : 5.4
SYMPTOMS You see three lights on the Ring of Light (RoL) flash red on the front of your Xbox 360 console. The upper-right quadrant light is the only light that does not flash red.
CAUSE The three flashing red lights may indicate that your Xbox 360 console has experienced a hardware failure. Please read the letter that discusses warranty changes for three flashing red light hardware failures.
MORE INFORMATION
If you suspect that you are experiencing this issue, you can submit a console-repair request online. However, before you submit your request, we ask that you first try the following two steps to verify that you are indeed experiencing this issue:
1. When you turn on the console, examine the light on the power supply. The power supply light should illuminate green even if the three lights on the Ring of Light flash red. If the power supply light is not green, please follow the steps that are listed in the following Microsoft Knowledge Base articles:
906101 Xbox 360: The power supply light is red 906102 Xbox 360: The power supply light is orange 906103 Xbox 360: The power supply light is not illuminated
2. Turn off the console. Wait 10 seconds, and then turn on the console again to see whether the symptom occurs again. If your console continues to display the three flashing red lights, your console may have to be repaired. For information about how to start the repair process online, please visit http://www.xbox.com/support, and then click Console Repair in the upper-right section of the Web page.
Note: The online console repair service is currently not available in all countries or regions.
