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

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?

Doesn't sound good 

Apropos, any signs of life when connected?

  hi-no sign of life-just controller going warm

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

That's why the R1 has burnt.
