My PS3 CECHE01 had that kind of ylod u mention and a weird issue every time i tried to power off the console it just 3 beeps and flashing red light (no ylod) my first attempt of repair i used was the heat gun only on the nec tokins from both top and bottom of the board 350º 3:20mins on both sides just to make sure and test if the problem was tokins related. After that my console turned on every time with no issues, the only problem was that it ylods with demanding games like the last of us and bioshock infinite. Then i did what was mentioned in the thread, i replaced just 2 nec tokins and trust me im an amateur at soldering small things , one from the rsx and one from the cell (in the side of the board in where rsx and the cell are not present) with 4 330uf 2.5v tantalums capacitors for each tokins. After that my old fatty boy came back to life like brand new and can now play every single ps3 , ps2 and ps1 games with no issues and it fixed the weird problem when powering off. So replacing the tokins are the real fix for that kind of ylod on the ps3. Hope u can solve ur problem by doing the procedure with the tantalums as its mentioned in the thread. Good luck
Sorry for my english :P
