hey guys
i have a ps3 slim 2001b when i press the power button system beeps but wont cut on.
the button does not show the red or green power light either.
i opened the console and when it beeps upon pressing power button
the fan doesnt move. is this a rare ylod or just dead? eject button also makes sound.
never had this issue. thank you to all who help and make this community #1
 
So let me try to understand your problem, you press the power button and the PS3 immediately cuts power or beeps 3 times!?

If after your press the power button, goes green and immediately the PS3 cuts power, that may mean the NEC/Tokins are done for it, and need replacement.

Unfortunately i cannot help you on how to replace the NECs with Tantalum Capacitor, but if your PS3 doesnt even turn on when insisted, you will need to repalce the NECs with Tantalum Caps in its place.

I cant say to replace the PSU, because thats a rare case, and cant say its your GPU its done for, because it would beep 3 times, like a classic YLOD.

I wouldnt advise you,but what you can do its tamper with the PSU, if it has potentiometers, you should search on how to tamper with them properly, but you will need to open your PSU, which its dangerous, if you never worked with live high-circuitry.

If your PSU has potentiometers (which some dont), and after you override the potentiometers, your PS3 should have a stable rail voltage, which means your PSU its done for it (thats just extreme cases), but if your PS3 doesnt have a APS-250 PSU with potentiometers, dont bother changing the PSU (unless you have a spare to test), ive made a usefull tutorial on how to connect a ATX PSU to a PS3 Slim properly in the PS3 Tutorials, which you can test yourself and report back.

Hope i could be helpful mate, good luck :)
 
did this happen all of a sudden or gradually? i.e. PS3 booting to XMB one day but appearing dead the day after, or PS3 booting to XMB, then taking longer and/or taking more and more tries to boot up? or did something weird happen right before the PS3 stopped working? (don't know, noises from the console, or the fan stopped while playing)
 
thanx for the help guys.
someone gave me the console.
there is no 3 beeps and no lights turn on.
when you press the power button you hear the beep but n green or red button light on power.
if you press eject you also hear the beep but the console doesnt power on weird.
thanx anyways

so it was already faulty when they gave it to you? then I am going to assume you don't know the infos I asked.

it just goes "beep" once and nothing else, am I right? I would try to replace the PSU with a healthy one and see what happens. If nothing changes, then I would think it might be something power-related at the motherboard level (i.e. capacitors as Naked Snake suggested). Look for weirdly bulky or burned components, burned / broken paths on the circuit board, or anything that could look odd. Unfortunately I don't think I can be any more specific. Moreover, I am not familiar with the Slim models so I think I cannot go any further.

But if you are familiar with multimeters you might test if the PSU effectively outputs the power needed by the system, so that you wouldn't even need to replace the PSU since you would know that yours is functional.

The buttons, green/red leds, fan are connected to syscon
And the PSU have a voltage named "5v standby" that feeds the syscon when the PS3 is in standby

So you can deduce syscon is working when the PS3 is in standby (this is why red led is turned on in standby), and is monitoring the buttons. When you press power button syscon sends a control signal to the PSU to "enable 12v power rail"... and the PSU sends back to syscon a signal we can name "power OK"

-----------
So i guess the fact that the PS3 doesnt reacts when pressing power button means syscon is not receiving the "power OK" signal from PSU... and syscon refuses to turn on the PS3

So well... as mentioned, you should try to replace the PSU

And for a better confirmation you can try to turn on the PS3 without the heatsink, and a finger on top of CELL
You should not feel any heat on the finger because CELL is completly inactive
And this is why the fan is not spinning, syscon knows CELL and RSX are inactive so there is no need to spin the fan

first of i thank you for sharing your knowledge.
tried 3 psu's all same model. no luck. i beleive this one is paper weight.
thanx again for the help

Next thing you should take a look is at some components in the motherboard that works as fuses
Are labeled as THRxxx if i remember correctly (because the technical name is thermistors)

Are located in power rails of the motherboard... if one of the thermistors is fryed you have a part of the motherboard disabled
Take a look if there is a thermistor for the 12v rail
