Why does Playstation 3 slim shut down seconds after start up.?

With old power supply, after turn on i loose the red led and have to disconnect for 10 minutes to press the power and see the green light for 2 seconds.

After replace with a new power supply, the system starts on for 2 seconds and shutdowns the led indicator disapears and i have to press the powerr button for the red indicator show's up

I just replaced the thermal compound on mine today. It didn't want to start up properly afterwards but did eventually - now seems to back to normal. I had several weeks trying various remedies including a good clean out and adjusting the potentiometers. Try the easier stuff first then replace the thermal compound if all else fails. I found a good 35 step guide to stripping it down to the chips, cleaning off with alcohol and replacing with new compound. It takes a while but if you follow the guide carefully and put all the removed screws in some sort of order you can revive your PS3.

As far as I have been able to find, this sort of problem is either the cpu or the graphic processor, to fix you have to reflow the solder.. problem may be fixed by just cleaning out the old thermal compound and reapplying but only if the solder is intact.. and if you have the machine open you may as well reflow the solder while your at it.. I have read and watched so many vids on how to do this and still haven't done it yet. I know they recommend using 'no clean flux', but before doing anything remove the PRAM battery clean everything well, clean off old compound with isopropyl alcohol.. and if this doesn't work then I don't know what it could be..

I'm sure someone more learned in this field would have the answer.

I took my air compressor to mine it was doing the same thing blew out all the vents without even taking it apart plugged it back in it worked perfectly. But you got to blow out all vents on all four sides plus all the hookups + inside of the CD insert as well.

I Have the same problem I tried so many things and none of them helped wish there was a solution so anybody that knows a solution Please reply Thanks

i also have this problem with my ps3 super slim

This is unbelievable but I got around this issue by doing this:

1. Immediately you turn on the PS3, press the eject button to eject the blue ray disc.
2. Once you eject the blueray disc, the PS3 stays on but you won't see anything.
3. Turn the PS3 off with the disc still ejected, and then reset the PS3 (turn on and hold till it beeps)
4. After it resets, and turns on, you can reinsert the disc and enjoy.

Green light stays on for a second and then no light, the console completely shuts down. Pressing the power button again turns on the red light. Pressing it again repeats the cycle. What could be the problem?

I moved my potentiometers but, unfortunately did not mark them before moving. So now I have no idea where they were to begin with.. I feel like I should not have moved them.. the machine still turns on sometimes.. anyone got any advice on this. Photos of where they should be would be great I'm going off the cross indent in the top of the potentiometer, mine is a plus instead of a cross. I have turned it towards the blue square thing on the end, while holding the unit with the potentiometers towards the top.

I hope I have explained this well.

Please help me.

It could be the blue ray player because everything runs throught it we checked the power supply and even used a 12 volt cource that had the same amout of amps and still had the same problem with the ps3 meaning it could most likely be the blueray player

Buy a PS4 Console…..

It is not the power supply…if it were the power supply the fan would not boot up when you start it... Now to fix it we got two options… option one open it up get down to the processor buy a kit and fix it with that…option 2 you can take a hair dryer for 30 minutes blow it in the vents taking a break every 8 minutes for 5 minutes when you're done it should work it works 90% of the time I hope this helps…

mine just doesn’t turn on if i put the original hard disk in there, i formatted it already on pc and it just took me to an screen saying that the hard drive need to be formatted, today i had no other choice so format it again via pc and reformat it in ps3, ps3 turns on good without the disk but, if i put again the disk, it just do what connor said. don’t know what happening, i think that i’m gonna test a new hard drive to see what happens

well, where to begin… (might fix slim ps3 aswell) fyi bare with me i tried to explain it as best as i could. first time trying to fix a ps3

I thought eitherly the power supply or applying thermal paste would solve my problem but, no. I messed with my PS3 and this is what helped me. 1. take Panasonic battery out for like 30 sec. 2. clean dust. 3. Tweak black and white cables beaneath power supply. 4. Underneath the fan there are 2 tin squares (they both have to be touching each other along with a small plate next to one of them). 5. On the power supply tweak a white screw/potentiometer. Saving tons of data now!
