45 minutes - 1 hour
Grandson's Xbox encountered red ring of death for second time. Had it repaired professionally, only to have the same thing happen again in a 2 month period. Was not going to waste money on bad fix again.
Bought ifixit Xbox red ring of death fix kit. Followed all the directions exactly and Xbox works again. Grandson happy again. In doing repair found professionals are trying to duplicate your fix but are using inferior parts, and paste.
If this 59 year old grand mother can fix an Xbox any one else should give it a try. The only advice I have is to follow the online instructions and view them a few times before starting. The hardest part was opening the cover.
