Samsung LCD PSU PWI1904SJ (D) Rev 1.1

[Thermaltake]

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.

Ahh right on my board they are 1000uf 25v and were from factory but mine is slightly different, evther way both will work fine.

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