Number three for me then. Sure wish i would have seen this info before :D

Well, i used a heat gun (1500W) and flux, 500 Celsius, for five minutes on the delidded RSX. 4 minutes in, a capacitor right next to the RSX came free after touching it with my tweezers, this was my method of knowing when the solder has gone molten, so i waited one more minute to make sure every...

I have a CECHH that i revived after replacing 1 RSX tokin that freezes and shows artifacts ten seconds after booting, responds to being pushed on the RSX chip, presumably because of cracked joints, so i don't really mind trying seeing as it's useless now.

What would delidding do, besides lowering temperatures once the system is working? And another thing i would like to ask everyone, anyone know of a good tutorial on how to reflow the two main chips? And can it be done with a regular two setting heat gun? Thanks.

I'm sure most of us here can relate to this:

Considering the PS3 is YLODing again, no.

Update on the 14 x 470uf 10V and 1 old Tokin per chip CECHG that i revived after going over the board with the hair dryer. It went back to the same 2-3 second YLOD, after working fine for five days. I am using chinese tantalums, so i presumed maybe not enough capacitance is the problem, added 3...

Well i can't say for sure now, because i revived it, presumably, only temporarily with a hair dryer. Once the tokins die again, maybe i'll find that tantalums aren't enough and i need to add MLCCs to get it running as other people were talking about earlier in the thread. What you could do is...

By the way, i have to thank you guys. If it wasn't for you, i probably wasn't going to touch this PS3 anymore and just use it for parts because i certified it as dead :D I replaced each tokin with 3x 470uf except one per chip, added 3 more tantalums per chip to compensate for the ones i'm not...

Oh, i'm a dumbass. I left the fan unplugged so it shutting off was just it overheating, hahaha. Now it runs just fine without shutting off. I guess i'll wait until it YLODs again. And i still have space for 4 more tantalums per chip, so maybe i won't even remove those last two tokins. I'd...

I fixed it, for a minute (the CECHG). This is the first time i saw it run. The system now has 14 470uf 10V caps (yellow chinese cheapies) + 1 old Tokin per chip. I used a hair drier, hottest setting, on the whole board, both sides, focused on the last two Tokins especially and it actually fired...

That's a great question, does anyone know? But on the topic of having so few caps there, the CECHH also has what seems to be the same amount of caps there, and i did revive it with the replacement of one Tokin. Maybe more Tokins need to die before a tantalum replacement isn't sufficient enough...

And i just checked over both sides of my board comparing it to these: https://www.psdevwiki.com/ps3/images/a/a8/SEM-001_Bottomside.jpg https://www.psdevwiki.com/ps3/images/1/10/SEM-001_Topside.jpg Both have the exact same components, besides some variation in fuse appearance. All fuses test okay...

https://www.psdevwiki.com/ps3/SEM-00x Here you can see three different photos of the same board. Despite the photos being so blurry besides the one i showed you before, they all seem to be "missing" all those same caps.

Don't get your hopes up too high. I replaced all but one tokin per chip (to avoid having to make the bridges) 3x470uf 10V, and then after that didn't work, i added more caps to compensate for those last tokins, and later 2 more per chip, same result. I did however get a CECHH working after...
