Had my first YLOD the other day whilst trying out the new Max Payne fix.
I should have known it was coming because over the last couple of weeks the PS3 has been turning itself off after about 20 minutes of play.
The PS3 is the old 80gb phat which i have had for a few years so not done bad out of it.
I have spent the last couple of days researching various guides which include stripping the PS3 and using a heat gun on the RSX chip plus replacing the thermal paste on the chips.
I have seen people putting the motherboard in the oven which sounds a little extreme.
I gather it is the solder that comes free on the RSX chip which causes the problem and my soldering skills are pretty decent so wondering for people who have fixed their YLOD what they feel is the best method to achieve the best results and possibly a longer fix.
