i get the YLOD about a month ago and looking in the internet i finally get to ifixit.com; i check in different places for repair but the price was high so i decide to give it a try and for 40bucks i fix my ps3
I use the repair manual and its actually really easy, i did it step by step, i actually take more than 4 hours for the whole process but at the end i get my ps3 to work again
Be pattient, the guide said that take like an hour but i actually take more than 4, i have to say that i have no experience in repairing electronics so if you are like me pattience. I recomend you to numerate the screws for their step number for an easy reassambling.
