Some friends recently experienced the YLOD after overheating. They tried to repair it but couldn't discover what happened.
The guide was right on! I really liked how the pictures were framed well enough so I can always tell where I am on this huge device. The hardest part was replacing the PS3 top cover.
Both the guide and the guide video place a lot of emphasis on making the motherboard level while heating the GPU and CPU. My home is not very well-made and I don't think any of the floors are level. I took a trip to the hardware store for a $2.00 circular bubble level. I recommend this extra tool because a level setting is so important for a proper repair.
