My ps3 wont turn on there is no picture fans shut off right away within a few seconds. wonder if it is the harddrive or the power supply. but i do have power

is there any clinking noise as it shuts off? I have an acer laptop that does the same thing.

seems like the harddrive is not responding to the start command right away.

that's a tough one

It is possible that the power outage has damaged your power supply, but there is a way of checking this. Unplug from the mains leave it for a minute, the switch at the back of the ps3 turn to the off position, plug back into the mains, turn the back switch to on to off then on and see if the console will power up, if not, and you have no warrenty left you will have to open up the ps3 there are guides on how to do this on youtube just have a search and you will find quit a few good videos, unplug again from the mains, take the top cover off, looking from the front of the ps3 on the left you will have a rubber insert, with a sticker on it, take out the rubber insert, inside there is one screw you will need a star ended srewdriver, somtimes a small alan key may do it, once undone and out put a bit of pressure on the top and slide it towards the left in should just slide and pull off, you then need a philipes or pozy drive screw driver to undo the 6-8 screws on the top of the inner housing, once they are all undone, from the back pull up and towards the front of the ps3 and it should come away, becareful not to snap the plastic clips.

There you will see the hardrive on the left and the blue-ray drive on the right, you will be taking out the harddrive there will be four screws holding in place, undo these and unplug the wires from the hdd and pull upwards it might be a bit hard because it plugs in the board with 2 prongs make sure you are careful not to go to rough it will come off, once the harddrive is out set the switch at the back to the off position and plug back into the mains, turn on by the switch at the back, what you are doing here is a hard resset once done that and the ps3 is unplugged again from the mains you can put it back together again, you same way you took it apart, make sure the screws for the inner caseing go into the right holes there will be a slightly shorter screw, make sure this one goes back into the right hand back corner, the others are all the same length so no need to worry about them, once back together plug the mains back in and power on from the back and see if it will boot, if you still have the same problem then it is likely that you will need a new power supply. hope this helps and post back what happens thanks.

u have bad power supply 2 bad capaciotr on power supply

HI, the power supply is unstable or weak. you will need to replace this failing power supply soon. it is damaged.

Hi my name is Juan and unfortunately your ps3 is dead what happen is that for some reason it got so hot and the processor stop working when you turn on the ps3 it does a self test and if something is not working right it turns off immediately with a green yellow red light so don't spend your money in another power supply I can guaranty to you is not the power supply I do sell and fix playstations and this is why I know this this problem is common on the 60Gb and 80Gb also in 40Gb but not like on the 60and 80Gb

may be the connection to the smps is not right 

or may be the fan blew out

It sounds more like your power supply isn't charging the battery.
I would first check to see if the power supply is working properly (you can do this with a regular volt/amp meter, or by taking to your local electronic repair shop). If the power supply turns out to be ok, then next have your battery tested, even new batteries sometimes go dud.
These are both inexpensive (if not free) things to check before you just throw it away or get into a motherboard/processor.
Let me know if this works or not.

Can you describe your ps3 and how did you connect it to your tv?
Try connecting your ps3 to another tv.

This happens because your CPU is overheating, open your PC and blow any dust off the openings and CPU/Power supply fans, if you think one of the fans is not working... replace it.
