I hear THE GETAWAY in the background, i bloody love that game, played it a lot on the PlayStation2 back in 2002, still do today, nostalgia hits you hard.

yeah is THE GETWAY 1 from ps2 my brother was playing i play with fan above of power supply because its get hot from these systems we need to accelerate the ps3 fan because they run very hot to XD

Are you running the original ZSSR5391A or the APS-227?

I mean the APS-227 doesn't even gets hot as the ZSSR5391A, which was indeed a furnace inside, the APS-227 gets warm, but not to a ZSSR5391A Level, so i don't see the hassle to worry about it, of course you can always go with the 287W APS-231 from the G Model, although reports suggest that stability is not guaranteed in the COK-001 Board due to the extra PlayStation2 Hardware, although i can confirm it works without any stability breakups on a COK-002 Mainboard.

is aps 227 but in europe power is 240v so can make aps 231 work hard and in the past i tried to put APS 231 in 60gb european and power supply burnt LOL

Really, perhaps the Power Supply was faulty, i never encountered any issues with my previous C04 with an APS-231.

When you see no new NEC/TOKIN thread updates, after a intensive week of reports be like....

If that was overheating it would report differently on screen lol

Novice's always do this kind of mistake, Austin himself claimed that perhaps he'll make a follow-up video on that PlayStation3, stating by cleaning it to get rid of the "overheating", but i am 99% that my money is on not going to make a difference.

But what i wanted to demonstrate, is how this is the easiest way to tell if the Caps are on they're last leg, the console turned on, no problems there, but at the short session of Ratchet and Clank - Crack In Time, it turned off due to an RSX underfeed, the more strain goes to the RSX the higher the uF Output the Caps have to provide, and if the RSX can't get that feed, this happens.

So really this might just be a small portion to this fix being that this eg is only good for this fix by the looks of it if we get a chance to actually see it happen. If the console is already in YLOD state which most are that are bought broken 2nd hand or when its too late to actually do something about it, then this doesn't really help yet. Its still just another stab in the dark with those to guess its this problem or not. would be good to see if he actually does a follow up to confirm too if we dont then we cant really count it as the NEC Tokin fix yet.

@Edwired u dont always get a message when the console over heats or has been running hot, if its been running hot in the past u wont know if its caused any other damage and the console wont tell u that either until its too late. Its only with the CFW that we are able to see what the consoles are doing but if its on OFW u obviously wont see this, especially if its already in YLOD state.
 
Think of it like a cpu/gpu overclock, you keep the vcore/voltage stock but push the further without increasing power and what you get is shut down or weird behavior or the old way of saying the bucket isnt full when filled because theres holes in it as it not going to hold it own....

I know that but if you stop the fan and let it overheat it shows that other message as for sure it not overheating i know the differences if the fan is noisy it trying hard enough to cool down the console i can hear it with a hearing aid in my right ear lol

This thread has been a really interesting read. I started working on a script for a video I just released on YouTube ("The Misdiagnosis of the PlayStation 3 Yellow Light of Death"), and this thread was definitely something I checked out when I was checking engineering resources and tracing early diagnosis during the scripting stage of the video a month or so ago. I have returned to find that it has reached 25 pages! That is pretty impressive.

I haven't elected to do any work on my CECHA model just yet, but I am happy to see that more people are leaning toward diagnosing their consoles. I hope to restore mine to its former glory once I find the time (and clean off my workbench!)

I will link to the video in this post in case you guys are interested (It does get a bit technical). Hopefully more people will question their attack of the YLOD, and maybe some will find a solution in replacing their NEC/TOKIN caps - something I did end up mentioning in the video.

Really happy to see the back and forth and sharing of information here - even when it gets heated at times - and hope that many a non-functioning PS3 will return a green light once again.

Best of luck to all that are attempting PS3 repairs!

Nice video :encouragement:
I like the way how it ends without giving a solution and the advise to keep the mind open and to avoid the the tunnel vision

Btw, one of the most important reasons why the xbox360 had more problems in the BGA solder balls than the PS3 is because the xbox360 motherboards suffers more bending
In the PS3 the motherboard is hold in place by lot of points of the metal shields that covers it like a sandwich, that metal shields are doing several functions, they prevents interferences, they works as heatsinks, and are also structural
When the PS3 is assembled the heatsink and the clamps at back are leaving the CELL/RSX like "floating" (like zero force, this is hard to explain with words, needs drawings, lol)
Also, at the back of the CELL/RSX in the PS3 there is an square of plastic that helps to spread the pressure into a square (in the xbox360 all presure is focused in a small dot at the back)

And, im not sure if what im going to say exists in all PS3 models, but in CECH-25xx series there are 4 "dummy" smd components at the corners of CELL/RSX that seems to be there to prevent the substracte to "squeeze" the BGA solders
Lets say... the substrate cant move down because is laying on top of them, touching them
The height of that components is the distance in between the substrate and the main motherboard

All this details prevents the bending of the motherboard and deformations of the solder balls

------------------
Disclaimer:
Im not saying that the PS3's are failproof against BGA problems in CELL/RSX
It could happen incase the PS3 had lot of overheats, the tin is not going to melt at 90ºC but it becomes "semisolid", and at microscopical level the metals starts damaging
