PS3 (Research/Experimental) - NEC/TOKIN Capacitors Replacement - YLOD

You be surprise if you put slim hard drive not the thick one that came with the ps3 there be air blowing out of the hard drive slot

Both are 2.5Inch Thickness, i can't see any difference between a 60Gb Seagate and a Later 500Gb TOSHIBA from a 4000 Series, the difference is bare minimum, a little slimmer but not thin as a paper slim, air from the Hard Drive will be blowing on the Phats regardless, but staring with the G Model thoes HDD intakes are closed and only for display purposes.

You can get the 1.8mm hard drive online

if u have a heat gun , just heat the nec tokins left with 360º within 3 mins and 30 secs

It didn't stay YLOD after that first time. I turned it off, let it cool and then ran it again on Last of Us. I installed CFW and set the fan to 34% minimum and temp to 65C: RSX at 54C, CPU at 62-65C when idle.

I can't get the YLOD to come back. Maybe I'll try again later today.

hey guys, can i use 2x 1000uf 6,3v for the rsx on the bottom or is that too much?

@yarrowman1 Every NEC is 1000uf, so I think you could.

Capacitors change voltage values while they're not connected to a voltage source. And since these are like bad electrolic capacitors, that also depends of the actual state of its internal "liquid", making a prediction of a YLOD can be complicated. You maybe will have to wait days to see any changes, or any YLOD at the first start up, but that's a clear sign that that PS3 is gonna have permanent YLOD very soon.

I now see NECs like they were spark plugs.

 

[Edwired]

It isn't a engline lol you have to see the nec as liquidized ice cream once it melted there nothing left there to inspect

 

[ElGris]

Hahaha, I said that because they behave like those. The PS3 start up depends of them, you know, like a real engine. If they're in bad shape, they can turn on your "engine" with some luck or many tries, but if no, then there's no RUM RUM

 

[Edwired]

LOL Just hoping the ps3 would arrive maybe at the end of the week due storm ciara and Dennis battering Ireland and England in the last 2 week it bad enough at the moment

So maybe I should just change the remaining NECs out and go with 100% tantalums.

Okay, so I tripped and fell into my worst fears. While attempting to remove the existing NECs, my knife slipped and massacred the board. In its sudden and swift path of destruction, the knife disintegrated three chips on the back side of the board.

Am I completely SOL, or is there any possibility of replacing these chips?

 

[Edwired]

Where about did you clip the knife? And what model is the ps3?

 

[Dark Paladin]

I'm working on an (AFAIK) untouched A01.

The knife slipped from right to left, starting from underneath where the power supply would be.

I outlined the direction of the knife slice, as well as the chips that are now gone.

Those are ceramic decoupling capacitors. Did you damage any traces? If not, all you have to do is solder in some replacement capacitors.

Post a picture of the actual damage so we can see what has happened and what traces, if any, have been damaged/cut.

 

[Dark Paladin]

I've posted some pictures previously, but hopefully this one gives you a better idea.

Red ovals are knife path. The scratches look superficial and does not appear to have damaged any of the traces.

Red stars are missing caps.

Yep them scratches are purely superficial, I cannot see any hint of the underlying copper traces so you should be good there, and very lucky as the length and path of the scratches suggests quite some force was used, and lucky it did not damage anything else.

EDIT: I would use some brush on lacquer over these areas just to be sure and to add a bit more protection back to these damaged areas.

As someone stated above you should only need to resolder the missing caps and it should be ok. I would look at the service manual to make sure you solder the right ones back into the right places. I have no idea were I have put mine lol, got way too many HDD's full for all sorts of stuff, but I know @wrx884 has one as well if you get stuck or you might be able to find one using Google.

Copy that. I'll start digging in Google just in case @wrx884 is tied up.

In the meantime, I finished removing all 4 NECs on the backside. However when doing a visual review, I see that my knife did brush against a trace in a different spot. In the right angle of light I can see bare copper. The trace isn't cut, but the copper is visible (see pic). Can I do the same lacquer brush against it to cover it up?

Yes, as long as the trace isn't cut, then I would cover this with lacquer to protect it and to prevent any kind of electrical short.

Now you have spotted this I would go over every part where you have been working just to be 100% sure there isn't any other little "surprises" waiting for you.

Yep yep, definitely will be doing that.

Fortunately my Google-Fu was on point tonight. Found the PS3 service manual and identified the missing caps. Now just have to source the parts, and then figure out how the frak to solder them back on. . .
