PS3 Super Slim turns off in 2 seconds after being powered on

hi members , i bought a broken PS3 Super Slim and received it today it still has the warranty sticker in place. What it does is when i plug in the power cable the red LED comes on and then i press power it then turns green for about 2 seconds and then the LED turns off completely.


ive done some google searches and this is a common problem.............


ive exchanged the PSU with a working one along with its cable and the PS3 still shuts off so its not a PSU problem


what else can i try ? ive read on google someone saying it could be the Capacitors on the Motherboard another person said the Thermal Paste is old and crusty and needs to be replaced



any suggestions welcome

 

I can assure you that it's not the thermal paste. I dont know if capacitors are to blame, but there is a small possibility that something is wrong with the cpu or gpu and the console needs a reflow. I would try to reflow it in your case, because that tends to happen on all PS3's ( although very rarely on slims and super slims.)

 

All the 12year olds on the internet think thermal paste is the cause for every fault... If it was thermal paste the system would run. Contrary to popular belief on reddit, the PS3 is not powered by a nuclear reactor...


sounds more like a short, seeing as the super slim is a top loader check the motherboard for liquid damage or other contaminates..

There is a super Slim,lol, chance that it's a faulty BGA as the super slim can get kind of hot..


it all relys on what the console does AFTER it turns off..

Does it loose power (no STB light), iirc the ps3 has a 5vSTB line for usb charging, check the voltage after the system turns off(also check the USB ports for shorts)..

check the 12v rail on the mobo, all STB and Power on functions are powered by 5v and 3.3v, if you only have power going to those areas ie: no 12v, STB will be normal but Power on will fail as the console can't power half the mobo..

with the console in standby check all voltages, I'll check if I have the service manual for the super slim, if I do I'll pop up the Test point locations/definitions..

check around the power connectors on the mobo, no doubt there will be some sort of protection there (thermal/poly fuses)..



to me it sounds like a short causing the PSU/console to reset.


Hope this helps

 

1. Does the fan test work?

2. Can you post a video of what it does exactly?

 

hi guys , i changed the the Thermal Compound and that did work was worth a shot though. I went to a electronic forum and the guys there said the Caps look like they are ' Polymer ' which rarely fail and arent the culprit.


ill look into your suggestions LeHaM tomorrow , below is a Youtube video of what it exactly does and i should say mine lasts the same amount of time on and not 2 seconds

the Fan does work when first powered on but shuts down as soon as it goes from Standby to Power ( green ) and then LED goes right off.

 

Yeah sounds like the PSU is going into protect mode, either a short or overdraw of current (again probs a short).. Have you taken the motherboard out and inspected it?

 

Bit of a long shot but maybe try pulling the hard drive out and booting up?

I had a Phat that got a corrupted hard drive mad would boot if I pulled the drive. Easy test and worth trying (though ing shot)

Alternatively can you get into the Factory Restore menu or does it shut down too quick.

 

From what op is saying, the system isn't even collecting the first boot stage. It's turning off right away. More than likely a short

 

thanks for the suggestion Grey Fox but this PS3 is a 12GB model and theres no HDD in it


LeHaM i plan on working with your tips ive been busy lately installing a CR4 XL ( Coolrunner 4 ) in one of my 360's , it has been a success

 

i did some checking of Fuses today on this PS3 and can anyone confirm that what im probing in this photo is a Fuse , interestingly it comes up 389 ohm which i read if Fuses have a huge reading they're dead

 

That looks like a resistor, what number written on it?? I think THXXX is that blue colored component or is not used on this mobo the pad next too it is empty

 

yeah i think its a resistor too as i got my magnifying glass out and its says 391 on it , i googled it and at Digikey says they're resistors.............


probing im getting off of that blue one 2.7 ohm

 

I guess it's safe to say the fuses are not the issue..

 

morning LeHaM im from Australia too , ive been looking into Fuses overnight and someone mentioned the Fuses are ' self-resetting ' thats why im getting values on my DMM that make them seem ok. So im thinking of replacing Fuses on the Super Slim ( 2 sec off ) and the Slim that just died yesterday , i still feel terrible about that too.


ive also taken a brief look at traces on the Super Slim and nothing stands out but i need to do a proper look and get the DMM out for continuity


i got a Cobra ODE waitng for me at the post office , would have been awesome to gaming today but sometimes shit happens

 

i just did a proper inspection with a torch and checked the traces all look pretty good , there was one area where something had slightly scraped across some lines but i did a continuity test and the traces arent broken

 

Can you pop up a photo of the scratched area

 

Cracked balls under the GPU. You won't be able to fix that. It came out bad from the factory. And now that you opened it SONY might refuse service, too.

 

Would the gpu cause the system to loose power though??

 

The PS3 has a sort of system manager sub CPU called "SYSCON" which does a extensive power on self test. If anything fails it does the generic "panic" behavior which is three beeps and light both red and green lights at the same time. Peasants call that "YLOD".

 

I see that's a good thing to know but the OP says the system is loosing the led upon power up.
red>green 2sec> off
im just wondering if this is due to "SYSCON" or something more sinister ie a Mosfet but idk ...
