    Samsung LCD PSU PWI1904SJ (D) Rev 1.1

    I unsolder few capacitors on this PSU long time ago and got new ones now but forgot place where they belong on board. I searched on internet for some datasheet or some manual for that board but I couldn't find any, can someone help me with this, thanks.


    EDIT:
    I think I found it, correct me if I'm wrong

    C205 - 16V 1000uF
    C206 - 25V 330uF
    C31, C202, C201 - 25V 470uF
    C104 - 35V 47uF
    C204 - 50V 1uF

                  Don't know why you need a pic. I wrote all the info. but okay, thanks.


                  Question, is it okay to remove that glue on PSUs I read that they can turn conductive after some time and cause trouble.

                      Your almost correct but on my Psu these are the PN's:

                      C205 - 25v 1000uf
                      C206 - 25V 330uF
                      C31, C202, C201 - 25V 1000uf
                      C104 - 50v 47uF
                      C204 - 50V 1uF

                          Also the glue should be fine.

                              On C31, C202, C201 I am 100% sure that 25V 470uF were there, because I took picture of bad caps on them so you have a bit different psu than mine. I remove the glue because on few last PSU that I was fixing they started to turn brown and that's no good.

                                      1000uf is a huge jump from 470 I will stick to original 470.
