(I have posted this question on other forums also, mostly xbox forums, but this forum has to do with bad capacitors, and seeing that my problem has a bad capacitor in it, I thought I'd post it here too.)
I just recently got an xbox off of ebay knowing that the power supply wasn't working in the hopes that I could repair it. I took a look inside and sure thing there was a capacitor and some sort of chip that were looking kinda burnt. I have attached a whole lot of pictures for all your consideration to see if you can help me out with what I have to do.
Just two days ago I ordered a soldering gun, solder, flux, and a multimeter in order to do this project. I am assuming that all I have to do is desolder the 'daughter board', desolder the capacitor and chip and then find replacement parts then solder the whole thing back again. My question is: I haven't been able to find that chip online anywhere - you can clearly see the serial number on it, but I could not identify the part. Any help to identify the chip that I need to order would be much appreciated. I also forgot to mention that my power supply is a DPSN-96AP.
On the chip itself you can read out 1L3 then under that DN**001D. You can not really make out the two stars **. However, there is a thread on another forum that shows a similar (I am thinking identical) power supply as mine. (It can be found here http://forums.llamma.com/viewtopic.php?p=87675#87675)
In the first post of that thread, you can see the similar chip to mine - you can read that the chip has a "1M2" then under that "DNA1001D". Once again, help finding what this chip and where I could get one from would be much appreciated.
I'm pretty sure that the capacitor that I need is a 25v 47uf one. As to the size that I need (I guess speaking in terms of mm) I'm kinda clueless. I heard that Rubycon has really good capacitors. Any ideas for what brand I should get? Also, where can I order a few (like 5) for cheap?
I am also concerned about a few more things: In this thread, it seemed like there were a few problem spots on this power supply. I took pictures of R901, D902, and the fuse (or at least what I think is the fuse).
D902 has a small brown blemish next to one of the contacts. I also took a picture of the underside of the board and it too has a small brown blemish. I was hoping if anyone could help identify if its burnt out and if so, what replacement part I need to get.
The following are all the pictures I've uploaded. I could get more if you require them.
Thanks in advance.
