Original Xbox Power Supply Repair - FTPS-0002

[NatoPotato]

Hey there friends!

I have an original Xbox power supply, model FTPS-0002, that isn't showing any signs of life. I have never really done power supply repairs before but I'm eager to learn so I am hoping someone can help me diagnose this.

The issue is that I get no 3.3VSR standby voltage which in turn leads to no 5v or 12v. A couple things I have noticed in my initial inspection.
Resistor 25 and 29 are both reading OL, Capacitor 17 and 20 seem to be leaking as seen in the photos.

So far I have confirmed that 240v, main fuse and the 400v cap is functioning correctly. Then I am completely lost after that.
My only hunch at the moment is to replace the leaking caps to see if I get any different readings, not sure if that would cause issues with the resistors though?

Thanks everyone!

change all the electrolytics for panasonic FR series - that especially goes for any 1200uf caps that foxlink liked to use.

cant help with the resistors right now - i dont have any open.

Thanks heaps for the input. What would you recommend to remove the glue?

i use a combination of tweezers to pull small bits, longnose pliers on big bits and a small flat screwdriver for lifting/scraping

I have the same PSU and need a list of the resistors on it, the color bands on mine are all unreadable.

Re: Original Xbox Power Supply Repair - FTPS-0002

so that psu is universal voltage?
or you have a 110v version?

@NatoPotato

you have possible cracked solder joints.

resistors are clear in your photo's - they probably work

R25 = 1k
R29 = 1k or 3k, hard to tell if it's brown or orange at the end
