Ahm, I would just like to highlight 3 key notes about fixing Xbox 360 problems.
#1 tip to avoid Xbox red ring of death is to prevent Xbox overheating.
#2 never try to re-solder Xbox your own unless you are knowledgeable at it or you have a repair guide with you.
#3 Don't wrap the damaged Xbox 360 console with a bath towel, it will not do good to your Xbox.
