Xbox 360 Red Ring of Death

The problem that haunts all 360 owners, the red ring of death. This occurred recently to my 360, the 3 flashing red lights. So what do you do? I tried online support first, for some reason the online form would not accept my post code eh? So I had to call, I bought this 360 in 2006 (it was my second) and even with the extended warranty for my system it would not cover a free repair. I was to it would be 70 pounds for a repair and it would take 3-6 weeks of precious gaming time. So I looked to eBay and found a 360 core system for 50, bought it and It arrived today in full working order. What I will do thought is try and fix my old system. There are so many repair videos and repair kits. Opening the case voids any warranty, but if you are already outside the warranty date what harm can it do? The most viewed 360 repair video is below. Good luck with fixing yours, I will post a video soon!
