  • please some help on finished sproggy

    hi,
    today after getting a fine heatsink - my sproggy 2.8+ is now 100% finished but not working
    all output voltages except 5VStb ( purple wire ) are 0V

    All is connected after the shematic i got from maestro
    I think its coming from the relais :
    the relais is not clicking , and I have no ground on on of the pins so that might be the problem -

    here are some pics of mine perhaps you find a mistake
    I build it after this shematic :

    My sproggy in unfinished stadium:


    here are some pics of the sproggy
    big images to see better

    thanks much for any help !

    felix


    BTW : what voltage do i put on remote line ??

    so here another pic wth explanations on it - so there must be somethiong wrong with relais layout ?? please look at the last link on my previous post to see if i did something wrong



    Many
    Thanks

        i folowed a trick to put a big C between 5V and GND but still mobo refuses booting.
        I tested 3 Mobo's but no success -

        please anyone with an idea ????!!!!!

        :cry:

          ok buddy let me see .. do these check before i answer you ques..

          a) connect both main and remote to positive and ground to ground

          b) check if your getting the 5vstby from the 78L05

          c) connect ground to pin 14 and see if the relay click (if it does then check the volts on the PSu ..

          Let me know ..

            hi maestro

            a) done
            b) done I got 4.5V ,
            when PSU is on I get
            12V is 12,22V
            3.3V is 3.3V
            5V is 5.05V
            and 5V on grey wire
            all neg Voltages are also correct

            some one on Divx-car told me to try the following
            put a big C ~1000uF between GND and 5V .
            ( i made a picture to show better)



            c) works relais clicks and psu is on

            when PSU is off ( relais not clicked) i get 4.42V between green wire and GND. 4.63 V between purple and GND.

            could this low "5V" from the 78l05 be the cause ?

            thanks

              ok till now everything is fine ....

              Your sproggy is working perfectly fine... dont put the big caps... !

              now check the following...

              a) The pins on the ATX power connector is wired correctly... double check it ....

              b) Check the power good delay .... if its giving proper dealy use a multi meter....

              Let me know..

                ok for the cap - the guy told me that on his sproggy that worked so i tried

                I toked a ATX connector from a broken PSU of a friend of mine - not the cables /connectors which where in your semi kit i bought.
                so i think all is correct.

                for the delay what should it be ? how to measure it ?

                thanks

                  use two multimeter and check the +12 and after how long the power good kicks in ..

                  If possible change the chip 4049..

                    a bit hard to mesure - but 5V kicks in ~1sec later than 12V

                    BTW are the ~4.6V for 5 V stndby ok ?

                      ok after 4h this night and 2h today i figured out this:

                      - sproggy connected to mobo-
                      - pin 14 connected to groud via little wire
                      - the i give the mobo the pwr good - it starts

                      no way to start it with the switch

                      Any idea - last night i was not far away of trowing it out of the window or making it a AT PSU - I'm totally about it - until today cost me about 80EURO

                      Anyone wth a little idea please please please

                      EDIT


                      my voltages are the following - could someone please compare .
                      A=4.3V
                      B=PSU ON 3.7V ;PSU OFF 4.48 V
                      C=PSU ON 10.54V PSU OFF 13,28 V
                      D=4.95V

                      So what is the problem with my PSU?


                      Thanks

                        your voltages seems fine ... if your psu kicks on the mobo when you connect the pin 14 to ground then i feel your mobo is not giving ground through pin 14 use a ac psu and check if the mobo is giving ground on pin 14 and does the ground hold there..

                        your PSU is working perfectly as designed the 4.46 v on the stby is not a problem....

                        when your pin14 (gren wire) is given ground (not frm the mobo seperate ) does the sproggy kicks on and boots the mobo ?

                        Cheers

                          the mobo works ultra fine with an AC psu

                          via MObo Pin 14 seems not to bee grounded- only voltage drop i think-
                          when i ground pin 14 manually the PSU (relais) turns on and mobo starts fine .


                          EDIT

                          with an AC PSU its perfectly grounded

                          with the sproggy I have the following voltages
                          : B=PSU ON 3.7V ;PSU OFF 4.48 V
                          point B = green wire

                            ok felix your having a very weird problem ... you can replace the 2n3094 and see if solves your problem.

                              hi maestro , is it a simple NPN transistor or does it do somethong specific (caracteristiques) because cannot find it /and store also on those Transistor equivalent books

                              Tnx
