I hava a BC 80gb Motorstorm PS3 and the last couple of months my PS3 has YLOD 3 times now. I fixed by myself applying thermal paste and reflowing it with the heat gun and all. The first time I guess it was time, beacuse the PS3 is old (from January 2008) but the second time, after opening it I realised that the plate covering the RSX wasn't in full contact with the heat sink so that was the problem, but now I dont have any clue.
There is something I can do to fix in a more permanent way? Or anyone have a tip?
The weird thing is that the first time it YLOD while gaming, but the other 2 it YLOD when it was shuted down, I was playing then shutdown and hours later when I turned it on it had the yellow light.
I don't know but I think that keeping the PS3 vertical doesnt help to it.
