PS3 Super slim PS3 shutting down 3 sec after booting

Hello there, I've got an annoying problem to deal with..

So I bought this cheap superslim PS3 (cech-4004c with 4.82 system) from a guy after testing it : everything worked fine. I took it, launched it once I came back home, discovered the features, changed some settings, started looking for a way to jailbreak it... until it crashed when I wasn't looking.

No lights were turned on at all, as if it was unplugged. I pressed the power button, the red light came. Pressed again, the green light came and the console booted. Fine... until 1h later, when it crashed again. I restarted it the same way. However, when it happened the third time, it just couldn't boot : immediate crash 3 seconds after turning the console on (from red light to green).

This guy seems to have the same problem as me :
Could it be because of the PSU ? Thanks for your attention, I'd be glad to know how to fix this.

Alright. I've read many times that it could also be the motherboard, and if it was the case, I'd be f*cked... Hopefully it isn't, and fortunately there are a bunch of superslim power supplies being sold on Aliexpress from safe-looking sellers.
Thanks for the answer, I'll order the PSU and wait for it to be delivered (can take a whole month though), and I'll keep you in touch.
 
It sounds like I have the same problem with a super slim I have... Plug the console in, red light... press start, then it turns green and 2 seconds later it goes dark, as if there is no power. Press the power again, and the red light appears... I can repeat that over and over with no change...

I happen to have a working console, so I changed the power supply over, thinking that was the problem...

It changed nothing.

Might not be the same problem, but it sounds identical. Just thought I'd let you know you might be wasting your $$$

I have accessed the syscon chip and gotten the error codes from the console, but unfortunately no-one has answered my post requesting help finding out what the codes mean, so... yeah...
 
Hold on.. So basically, changing the PSU would have very few chances of working, and the true cause of the problem would actually be a short caused by the bluetooth/wifi modules ?

Oh no... oh god no, I hope it's not the case. I don't have any soldering tools and I don't even know how to solder things (especially when they're, like, 1mm small)... :cold:

But I truly don't understand : why did this short happen ? It worked well before, and according to the guy who sold it to me for fifty bucks (controller included), it worked well since he got it in 2013. No Bluetooth or Wifi issues at all. I even updated the system from 4.82 to 4.86 via usb (with the official update files from Sony website's 2020 archive) without issues. Did I just get struck by bad luck ?

There is a possibility that the PSU is at fault. You would need to diagnose/trace the fault yourself as per the first two videos on my post.

It's unlikely you'd manage to do anything with a soldering iron on the motherboard. What you would need is a hot air rework station or something similar, even then you would need a fair bit of skill/patience to carry out a successful repair.

Your console is coming up to 10 years old and unfortunately nothing lasts forever. From my limited research, bluetooth/wifi module faults seem to be a fairly common, perhaps it's becoming more common as peoples consoles age, IDK. At the same time PSUs are known to fail too so the fault really needs to be properly diagnosed before a repair can be carried out.

Seems like your console had the same problems I'm dealing with.... Did you ever bypass the short and at least get your console to function?
 
Ok guys, so fortunately I have a friend of mine who works in the electricity field (not stuff as advanced as micro-electronics though), I called him so that we can diagnose the PSU.

We took the PSU out of the ps3 and opened it. He said he didn't see any shortcut symptoms (i.e black-ish color on the board). We plugged the psu in and he took his multimeter, he checked for the AV input: it's OK. He checked for the DC output that goes in the console... nothing.
I realized that we tested the PSU alone, without it being on the console. So I plugged the small cable located next to the blueray driver (see picture with the red arrow, not mine), and we checked again, this time by launching the console : when it starts (LED goes from red to green), we suddenly get a 12V signal on the output, but it immediately turns off.
No idea what it means, but I guess I'm just gonna wait for the PSU to be shipped (gonna take a while).

Oh, and I tried (by pure despair) to start the console with the bluetooth and WLAN connectors underneath the PSU disconnected : not working. Is it good news ?

I'm trying to source a hot air rework station so I can hopefully try and remove the short from the board and enable it to boot. I will update my post once I have done this.
 
Kindly boot it without hdd. I have a slim model which was doing the same thing. I replaced hdd and it worked like a charm.

I'll be very interested to see how you go... I do have a hot air station I bought to change out Tokin caps, but I'm not experienced enough to track down shorts... But I might get courageous and give it a go if you have a win with yours... I had actually seen the "my mate vince" vids you posted... it was super interesting to watch them again, given how similar the problem is to his... I do note he never followed up on that vid though...

Well, the HDD was the first thing I checked. I tried booting without it, and even formatted it to FAT32 just in case (I know, it's useless, but why not, out of pure despair). Still doesn't works ! :(

Yes, its a shame he hasn't done a follow up video yet.

I plan to first remove the voltage adjuster and see if that removes the short. From what I understand this regulates the voltage into the wifi/bluetooth module from 5v to 1.8v. Failure causes too higher voltage to be supplied to the wifi module causing it to fail/short.

In theory removing this power supply should remove the short hopefully enabling the console to boot. Although I will never be able to use the wifi or bluetooth or update the console (which doesn't bother me).

I will update my post when I get around to doing it.
 
Any update on this? My 2000a slim beeps and turns off on cold boot. I have to attempt like 30 times until it boots up normally. Then it's fine. I turn off. Turn on and it's fine. Turn on after half hour...fine. Leave it overnight. Red light. Is this the same issue as we discussions here with wifi module etc? Or bad power supply?

In my case, there is no beep, the console just powers completely off... Doesn't sound like the same thing, but I'm certainly no expert... It does sound like from your description that maybe there is a capacitor in your power supply that is on it's last legs... That's the only thing I can think that MIGHT fit what you have described here... The other guys here will probably have a better idea of what's going on than I do, otherwise it might be worth starting a thread of your own to try and get more info before you look at replacing the power supply and possibly wasting your $$$... The obvious test is to have a friend with a slim console and swap out the power supply, see if that resolves the problem...
 
@Jarod A , buddy try to boot without hdd. Bad hdd can be 1 of many reasons for this.

@klein1876 in ur case, it might be a bad solder joint or nec tokins maybe

Thanks for the reply... I actually gave that a go already, but it was no joy unfortunately... There's no doubt the main board has a short in my case, so I think I know what's going on there...

my case is weird. On cold boot, i get a green light, nothing on screen, and then beeps after like 40 seconds and shuts down. any subseqent power up leads to a 2-3 second ylod. I keep trying and eventually the console boots and runs no problem. I turn off, try again half hour later, normal on first try. I leave for 6-7 hours, and the cycle repeats. I thought it was the power supply, so I have a slime 2000b with a working power supply. Boots on first tyr no problem. I put that power supple in the 2000a (with the weird cold boot) and same thing. I took the 2000a questionable power supply and put it in the 2000b and that worked fine. So i am ruling out a bad power supply. Could it be a bad power plug? I might try switching out the power plug. Also its not the hdd. The other theory of it being the nec tokins...doesnt boot until the necs get enough charge after multiple tries. I dumped the syscon tho and it doesnt indicate necs. I am going to try the power plug swap, and if not, i will wait and cold boot, first ylod ill dump the codes and see what happens.
