The other day my ps3 simply turned-off while it was playing a movie from a dvd.

I wasn't around so not sure how exactly the turn-off happened but what I saw was there was no red standby light.

1. Anyways, I unplugged and plugged back, red standby light appears.
2. Tried pressing the power button and it powered (green light appears) for a second and immediately turned off. Again, no red standby light.
3. I pressed again and red standby light appears.
4. Pressed it again and it powers again for second and turns off with no red standby light.
5. And the process repeats and it seems my ps3 is essentially dead

So my question is its the PSU or the motherboard itself? I tried the ps3 self cleaning procedure (plugging it while holding the eject button) and it does bring the fan to full speed so does that mean PSU is ok and problem must be with the motherboard itself? I'm just hoping it that it is the PSU.
 
By my assumptions,its a Slim, CECH-2100 or 2500.

We had many disscussions about this issue, since the day once a started a thread about a year ago, but never figured it out the issue.

Many who encountered this issue, and though the PSU was the issue, when actually wasnt it. You could try using a tutorial on how to connect an ATX PSU to a PlayStation3 Slim and see if it fix the issue, if it does work, then you are one of the lucky ones, but not to be an arse but i doubt its gonna work,even with a ATX PSU plugged in,but try it :)
 
Thanks for replying. Yes, I did search a lot about the issue but nothing conclusive.

About the PSU, the ps3 self-cleaning test that makes the fan run at full speed, is that not a conclusive indicator that PSU is fine?
Or the thinking is that the fan, even when running at full speed, doesn't draw that much power to make the PSU fail so a running fan is not an indicator of a working PSU?

And yes its a PS3 SLIM.
What say?

The so called Fan-Cleaning test,isnt a Fan cleaning,but a Service Fan Test, to make sure the Fan runs properly,but even with this issue, it will run the fan test, as it requires low voltage,only for the fan.

Many people mistake Service Fan Test with Cleaning Fan,which its beyond ridiculous :D

The PSU is fine, but the PS3 mainboard isnt, but you still need to connect another PSU to double check,but try connecting a ATX PSU if you have one, or a OEM PSU :)
 
Thanks once again.

I don't have any ATX PSU. Is there a possibility to test the PSU with something else, a multimeter? But I'm thinking that a multimeter would never be able to put a load on the PSU and therefore never be able to confirm that it's failing.
I'll try visual scanning of the PSU for any swelled capacitors or something like that.

You could try,but my guess the PSU is fine,as these shutdowns manifest a problem with the PS3 mainboard and not the PSU,but you could always try your luck :)

Why you keep bringing a PlayStation2 for a PlayStation3 problem? These are two different systems, one its a low powered 35W machine and another its a power-hog at 400W for the first gen and 160W for the Slims.

Its like trying to put a 120mm Cannon Shell into a 45 Cal Pistol, you know the end result wont work and wont fit,but you insist :D
 
If it's a slim w/ the psu that has trimpots, i've had success adjusting those in a FEW scenarios. You have to be extremely careful if you do, and tiny adjustments are massive changes. Those are Over Current Protection and (Idr off hand). Mark w/ sharpie before adjusting so you can return to original position if needed.

This may have just remedied the situation for 6ish months in my case, but i've not heard a single problem since I had to do that. You can tell if it will help at all by adjusting the tiniest bit, and seeing if it stays on longer. Just remember, if you do this, it is messing with the power delivery system protections.
