Xbox 360 is not coming on screen just red light on console

When someone say that his/her Xbox is having 3 red lights problem, It means it needs to be repaired. If you are using Cooler than it is not a cure but a prevention. You could have used cooler before acutally having the problem just to prevent your Xbox. But now you will have to either get it repaired from Microsoft (in case your Xbox's warranty is not expired, but one thing to note is that you will have to wait for at least 3-4 weeks to get back your Xbox) or you can Fix your Xbox's 3 Flashing red lights problem yourself with the help of DIY Video guide available on Internet. You can fix yourself without any technical knowledge.

No! Check with 800 support the warranty was extended on most xbox 360 with the 3 red lights. Ours was repaired when we thought our warranty had ended.
