I thought I was in the clear as far as the 3 red lights goes for the XBox 360… it happened, I was under warranty, Microsoft send a cardboard coffin, and I sent it back. End of story.
Oops, it happened again. There’s no free lunch this time. Even if I paid the $100 to MS to repair it, they would only give a 90 day warranty on their work. So, either buy a new one (with a massive extended warranty, of course) or try to fix it myself. After attempting to buy a new Arcade unit for $200 at K-Mart twice, but failing both times because they were out of stock, I went the fix route.
