    long story short---- there was a R23 1.5k 1/2w open ,i put the resistor and it started working and it stopped becoz the solder came out,its too difficult to solder with my big solder point .. [​IMG]
    then when i tried to solder again for better fix the whole strip came off teared apart.. i count do anything ,then i got carried away frustrated.. shorted from near by 16volts to other end ,nothing came up ..got angry and threw and broke it .. i lost my cool..pulled some capacitors and plucked wires..
    after a day i calmed down-- then
    i joined few wires and put the filter capacitors330uf/200v x2 (before it was330uf/250vx2) ,its the same problem now..i am getting same 5vsb ,and no other voltages.. i get 16v at one side of resistor but not on other side.. which has continuity to jumper..,checked with other resistor too i get the same result.. please help me ,i place the pics here before/after .. thanks
    by the way..i am trying to fix it so i can use it just for the case fans.

    400W of overall capacity is QUTE an overkill just for providing the fans drive power . . . . instead . . . .use a wall wart of the capability of the voltage / wattage printed on the fans. Even MORE room in the case, will then mystically be present.
    PLUS . . . you literally self describe yourself, as not having the required temperament and tenacity for any involved degree of electronics repair.

    well it was just lying there ,so thought i would repair it and use it for my may be 4-5 case fans .. all 12v i guess so, actually i did fix it ,just was trying to do it more better fix.. i lifted the damm micro pads off ,there i lost my cool.. well anyway i learnt my lesson ,when professionals and youtube are here i could try my best to be calm and repair to some extent as much i can.
