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

[Naked_Snake1995]

why ps3 fat motherboard is very weak and also quickly dead?
But some motherboard is very strong like Nokia 3310 old model hardware

Depends on what motherboard revision you call it (weak), if you are talking about the early COK Motherboards, they are basically a tank, besides the NECs they are basically bulletproof, thick and sturdy like all motherboards should be, after that $ony just cheaped on the Motherboard making it thinner and cheaper, so for me these are more prone to failure, just like the cooling system, i honesty prefer the early models built quality than the later model.

The heat-sink on a original PlayStation3 is the biggest heat-sink you'll see on a console, the amount of heat pipes on that revision is ridiculous, $ony did they're job properly, after that they just cheaped the hell out of it.

People just blame the unreliability of the Phats PS3s due to they're poor maintenance, all YLOD Consoles ive touched and repaired had the same issue, misuse and rammed with dust, thermal paste its a forgiven, and i suspect people threw them into TV Cabinets, but what people tend to forget, is that the original PS3 its a power hog, that's no denying it, so it needs a proper breathing room, any high TDP equipment that you'll throw into a TV Cabinet and don't maintain it, will have a death sentence, ill assure you that as much, PS3s are no different, i can guarantee you, no matter what model of the PS3 you have, if you don't maintain it, you can kiss it goodbye.

We can't compare a Mobile Phone with a Game Console, that practically makes zero sense, and the Nokia 3310 wasn't that much of a bulletproof either, yes it had a reputation for being indestructible, but it had a fair share of issues itself, but that was more on the battery hinge, that wouldn't make proper contact with the Motherboard, i owned a 3310 back in the day, so i am no strange to that relic, but bulletproof it was indeed.

Nokia 3310 was an awesome phone I had it since launch nothing ever went wrong with it only had to replace the battery once. Anyway back the ps3 topic there was no denying the fact that ps3 the first gen model are like a tank but damm it was power hungry and cooling was a tall order for $ony to maintain in a tight case but giving certain sacrifices in cooling for performance comes problems in a later date due to poor cleaning maintainces

The cooling solution was good on his own ways, the problem to be honest was the Syscon Fan Profile, it does keep it cool, although it prioritise quiet noise over cool temperatures, the machine its hot, but its not critical failure hot like the 360 was, but for me Syscon Fan control is pretty much useless.

With the fan control at 27/30%, with a proper maintenance and thermal paste, i can achieve similar temperatures as a 45/40nm PlayStation3, so the Phat Models aren't notoriously unreliable, they just need a bit more maintenance, as i $ony user for many years, i know they're quality reflection they're reputation.

which series mobo is better for ps3?
I think ps3 super slim

CHECHA01
PS3+PS2+PS1+PSP

People tend to praise the CECHA, and look down upon the CECHC and CECHE Series, but to be honest, all of the four existing launch models deserve a praise in they're own way.

I have my CECHC, although people dislike the model, i am particularly grateful for it, specially in the PlayStation2 Software Department, its true that $ony screwed us Europeans with the Launch Models, but the Partial-Hardware Models have a lot of potential with the PlayStation2 Library, 94% its a huge number for a Partial-Hardware Backwards Compatibility, and it can be patched, not to add that due to the lower interest on the model, not only is cheaper, but also the image quality is far superior to the CECHA/B Models in the PlayStation2 Format Software, this its due to the conjunction of both PlayStation3 and PlayStation2 Hardware working in tandem, the CECHA/B has the upper hand in Compatibility, but not in the Hardware management and quality.

Exclude the PSP part, without the homebrew, PSP implementation wouldn't be possible outside $ony's spectrum, not mention compatibility is just poor.

CHECHA is the best PS3 version even created.
Period. I don't find any image differences in ps2 in any of the newest models. The only thing better is the cec support in slim models and that's all

That's because you didn't compared them side by side to tell the difference, the CECHC/E PlayStation2 Image Clarity its far superior to the CECHA/B, again due to the Emulation of the EE, and the Upscaling reconstruction of the RSX.

The CECHA/B stays true to the original PlayStation2 Hardware Fidelity,, which is 480p, the CECHC/E take the same 480p/576p Signal, and gives the RSX the task of the pixel reconstruction, by Upscaling the image to 1080p.

I am not mentioning any (newer) models of the PlayStation3, so don't add Non-Backwards Compatible Phat and Slims to the mix, i am talking about the original 4 Backwards-Compatible PlayStation3s,with native OEM PlayStation2 Hardware and PlayStation2 Disc playback.

You know you can switch to rsx emulation at anytime from rebug toolbox right? Your argument is void.

"What i can advise is to get two original NEC/TOKINs and resolder them again into the CPU and GPU, and the rest with Tantalums."
I had removed all NEC Tokin and used all tantaluns.

"Its funny because for some, a full replacement Tantalums works like a charm even without the NECs present, and for some just straight YLOD, so something is failing here on the bridging department."
"A fuse has blown! Shorted/Damaged NEC can blow a fuse! If NEC replaced but fuse same, then same symptoms."

After removed all NEC Tokins and cleaned correctly the board I had used an multimeter to measure resistance and conductivity in both sides of NEC Tokin capacitor space in board.
PSU CELL RSX Positive side to ground resistance 0 and conductivity 0.
CELL RSX Positive side to ground resistance 0 and conductivity 0.

After added tantaluns not was fixed power off in less of one second.
All tantaluns was removed and now was changed the measure results.

PSU Positive Cell side to ground resistance less 1000 Ohms and conductivity 0.
PSU Positive RSX to ground resistance 1700 Ohms and conductivity above 1500.
CELL RSX Positive side to ground resistance 1700 ohms and conductivity value 1.

Perhaps something has happened in 12 V line trying power on without NEC Tokins even using an jumper in tantaluns.

Got my ps3 slim cech 2001a up and running this is my living room system for videos And music I have a cech2501a for all things gaming.

So on the cech2001 I remove the tokin lid to see what was going on and saw burn mark and since system had intermittent ylod I replaced both tokin to tantalum from a 3001a that was scrapped, my combination is 470×2 and 330×1 per tokin space.

3*330uf would have worked too, the tokins of the PS3 slim are 1000uf each

Btw, nice photo of the internal degradation of the tokins, ive seen others photos before but the corners of your tokins did look very bad

How can my answer be void? You clearly have zero knowledge on how the Hardware backwards compatibility works, so your answer its void, i suggest you to carefully read the documentation and analyse on how partial and full hardware backwards compatibility operate.

Ive never mentioned that the RSX was used in Emulation on a Partial Backwards Compatible, i mentioned its used for Frame Reconstruction and Upscaling, thats not Emulation, you are throwing misinformation to the wall in hope it sticks, why would the RSX would be used in Emulation when the Graphics Synthesizer is present? The RSX isn't efficient and powerful enough to emulate the Graphics Synthesizer alone, this shows in the discarded PS2 Emulation after the C/E series in 2007, the PS2SoftEmu.self, which was a replacement for the PS2GX_Emu/PS2Emu.self, that's the Emulator used by the Hardware Backwards Compatibility Units.

The Emulation switch in Rebug forces the Hardware Based Backwards Compatible to switch they're default SELF Emulation from Hardware to 100% Software, from PS2GX/PS2Emu to PS2Net_Emu, which is the Emulation used in the PlayStation2 Classics for the Non-Backwads Compatible Models, something that the Hardware Based Backwards Compatible Models don't do on they're own, that has nothing to do with what ive said so far!

Before you reply i suggest you to read some documentations carefully, because as of now you are shooting ammo in hopes of a hit, but you aren't hitting anything here,you clearly haven't done any homework before your posts.

The computation in Emulation is done by cell cpu as rsx is just a graphic card that does the shaders, special effects and a display output as it has nothing to do with emulation

On the PS2Net_Emu, that is true, the CELL does 95% of the workload, however on the GX_Emu the RSX only has the task of frame reconstruction and Upscaling, nothing else, since the Graphics Synthesizer takes care of the Graphics workload of the PlayStation2.

I decided to stay in for new years and take up the busted ps3 and figure out the way with a 2000w heatgun with everything covered before attempting to remove all 4 nec tokin nearest to cell and rsx since I had nothing to lose here as it for science process to get the tokin off without damaging anything around except the top part of plastic which is melted which is to be expected but not broken off. Now the method I used is not taking the tokin off but slide it away this way is you which resulted a smooth looking solder on the pad otherwise you would end up damaging the pads on board while forcing to break it off. The results are in on cell side I found one tokin as fallen to 1.264mf the other seems to hold around 1.299mf. On the RSX side it both have a reading of 1.306mf, here the kicker of the new untested NEC tokin that have a reading 2.089mf that a huge difference in the old worn out compared to brand new. That explained the symptom of the missing GUI menu due to the cell not getting either power or current. Hope this help

I've gone ahead and replaced the tokins on my 60gb fat (the cecha01) with 470mf/6.3v tantalums, but no luck so far! I installed 4 on the gpu side, and 4 on the cpu side (both on the top side of the board), but my ps3 is still failing to boot up. It does seem to be failing fairly quickly after boot, I measured it at about 3 seconds before ylod, so I'm not entirely sure if it is the tantalums (specially since it still doesn't start), or some other issue, as suggested by the OP.

I need to order more tantalums so I can do the rest of the gpu but in the meantime, does anyone have any suggestions of where else I can troubleshoot?

• I tested the power supply (it's an aps-226) and I seem to be getting 12v and 5v, but that's all I tested there.
• I did test the continuity between the tantalums and the pads, and it seems ok...

Thanks! Any help is appreciated... I've had this ps3 since launch, I've babied the heck out of it and I really want it back

 

[demetris]

I would suggest two things.
- replace the second tokin on the rsx side with tantalums
- remove that yellow wire and make sure the tantalums on it from - side are not touching the + on motherboard

I have a CECHE that I got on launch day and got a CECHA used, almost 2 years ago.

The previews owner nor me, have experienced any problem with this CECHA.
And I have not experienced any problem with the CECHE either.

Both have CFW with custom fan curves.

If both are working and I have yet to see YLOD with my own eyes, can I wait until the first sign of it happens?
Or can I have a dead PS3 with just one episode of YLOD?

If I understand this correctly the capacitors on RSX and CPU do not feed enough current and this results in YLOD.
So one episode would still be fine? or can it kill a ps3 from just one episode?

And there's any pratical test I can do with GT6 to check for failing caps?
Is there any specific track or something that would trigger it?

 

[nCadeRegal]

@marciolsf I would check and redo your solder work. Most failed installs here were from poor solder work. Also that jumper wire is really rough looking and I though snake said it is only needed when all tokins are removed not just one side.
