i have a 4GB silicon power
this isnt work (i plug it in and nothing happened)
i like know how can i fix this problem(capacitors failor or etc)
see these pic and help me please.

First check the resistor R1 1.5 Ohm.
Then on datasheet u should check basic voltage 5v / 3,3 v / 1,8 v on the pin of the controller.
Datasheet need to search. I have no for this controller.

ANDY is, as usual, right 

I believe PS2251-33 pin-out will do for 2251-50 too. Check that main 5V supplying pin with your DMM:

hi again
-i was put dmm on 20K-show 7.02
-no voltage in vcc5
whats de mather?
do you have book or anything to understand power and electronic

[Ksanderash]

Hi there. You don't need books here  That resistor had 1.5Ohm value before it had burnt (7kOhm now, right?) And 1.5 it's almost "zero" resistance. So you can short R1' terminals with a thin wire, and then plug in the flash into USB port.

p.s. For a quick test such solution will do, but for a long term operation you have to solder in there a real 1-2Ohm SMD(surface mount device) resistor.

hi-thanku for reply
how about warming up controller when it's connected?

[Ksanderash]

Doesn't sound good 

Apropos, any signs of life when connected?

[juan503]

  hi-no sign of life-just controller going warm

[Ksanderash]

Well... I'm pretty sure more than half that it is gone 

That's why the R1 has burnt.
