Do-it-yourself fixes are often cheaper in appearance - they do cost time and they even might cost you a completely new Xbox 360 system if you don't know what you are doing.
If your Xbox 360 is still in warranty and you have never opened your console, you have nothing to worry about, as Microsoft will repair it for free.
You'll need however to wait some time till the repairs are done.
On the other hand, if you opened your console for any reason (even cleaning) or if your product is out of warranty, there is only one way to save time and money and that's to do the repair yourself.
As a rule, the Xbox 360 is not easy to repair: it's a high tech product that requires a skilled touch.
There are some repair guides on the market, all trying to sell the easiest and fastest Xbox 360 fix, but not all of them offer a magic wand that will cure your Xbox from any malfunction.
There are two common Xbox problems that require troubleshooting: the three red lights of death and disc scratching.
The three red lights of death problem often involves an easy fix known as the "towel trick" - this provides a fast but temporary fix.
Although it sounds like a fix from grandma's recipe book, the towel trick seems to work for many users.
Apparently wrapping in towels an Xbox 360 touched by the curse of the three red lights of doom will mysteriously revive the console, if not for life at least for a few hours.
Any serious gamer who cares about his console will try a more efficient fix, but since many Xbox users reported success with this method, all we can do is to take their word for it, and this gives us the background to declare the towel fix the easiest and fastest Xbox fix.
The disk scratch problem is not so simple, but it does have some solutions via experimentation by DIY Xbox 360 users.
This fix requires the Xbox user to follow attentively all the steps in the book, meaning that you'll need to get one of the Xbox repair guides on the market and follow the explanations provided by their authors.
This will cost less than sending your Xbox in service and it will even take less time.
