Hi,

My PS1 9001 fall down from my hand, When i connect it to the power supply, it didn't work.
The power led indictor is off
So i assume that the fault in power supply unit.

So any way of getting a power supply schematic for the PS1 9001 ?

Thanks for any help,

You probably can repair it yourself. The transformer inside is the heaviest component and so I guess a bit resoldering here and there will put it back into service.
 

You probably could use a multimeter to check for shorts, my bet is there is a open connection somewhere around the power transformer,as Meridian said the transformer is the heaviest component, don't forget to discharge the supply capacitors first.
 

I have a lot of experience to repair a power switching:
some time the problem, coul be a resistor about 220 330K that change value
or power triac or transitor in short.
another thing could be a photocoupler for protection or some elettrolitic condencer in
lost.
check the bridge rectifier too..
I hope my help is good for You.
bye..
