Re: PS2 PSU no 12V
Sorry to high jack this thread, but being that it is already solved I am hoping to ask a few questions.
First question is for OP, rtstorm. Are you able to show what you did exactly? Is there a type of heat sink on the PSU that I am not familiar with, or are you referring to the heatsink on the main mobo?
Second question is for anybody that is willing to answer:
This PSU doesn't look like it is terribly complicated, so I was hoping for a general explanation on this circuits design. How does this PSU work?
I can see that...

Re: PS2 Slim Not Powering On
I'm not sure what a buck converter, so I am hoping I googled it right....Leave a comment:

PS15 is reading 8.8V.Leave a comment:

Re: PS2 Slim Not Powering On
I measured the fuse voltage wrong the first time. This is the results of the second attempt.
I don't know if I understand the basic principles of measuring this sort, but that should be answered in a different thread....Leave a comment:

Yes, that is what I am saying....Leave a comment:

Re: PS2 Slim Not Powering On
The AC Adapter prominently specifies 8.5V (this is not an OEM PSU). MM shows 8.88 from the adapter and 8.88 on the mobo where the DC Connector is.
I am not getting any voltage at the main fuse, however I am getting continuity between the both points of the fuse.
The standby LED is off.
A user, Lotas, highlighted a bunch of the fuses in an attached picture. I checked the fuses and they all demonstrated continuity.Leave a comment:

Re: PS2 Slim Not Powering On
I can confirm with 100% certainty that there is an abundance of flux in that area.Leave a comment:

Re: PS2 Slim Not Powering On
I found an identical part on another mobo and they look identical. They both have the same continuity tooLeave a comment:

Re: PS2 Slim Not Powering On
What kind of component is this? How do I test it with a multi meter? The only thing I could do was refresh the solder.
What makes you think it is broken? The center prong?...Leave a comment:

Re: PS2 Slim Not Powering On
Didn't know that was a feature. I took this with a higher resolution camera.
Also I regret to inform you that I removed whatever that component was last night. :boom:
No success.
If I can find it, then I will solder back on if necessary. I also have a spare board for components. Are you determining what it's function is by observing the circuit around it?...Leave a comment:

Re: PS2 Slim Not Powering On
I tested all of the fuses that you highlighted. One was giving me some trouble, so I cleaned it with Isopropyl and it's continuity was fine.
There are a bunch of teeny surface mounted components that are labeled with numbers such as "220" are these resistors or fuses? I have been testing continuity on them and they are most certainly connected.
I found what I believe to be a capacitor that is shorting out.

PS2 Slim Not Powering On
I have a Silver PS2 Slim SCPH-79001 which has a different motherboard than most PS2 slims that I come across. When I got this PS2 it was having issues reading discs, so I started to diagnosis the disc drive. After messing around with the system for bit it suddenly stopped powering on. I didn't smell any burning or hear any noises.
[LIST][*]I checked the PSU, it is reading stable voltage and is powering on a different PS2.[*]The power LED glows on a different system. (removable part)[*]The power LED changed to 'green' on a different system after pressing the power button.[*]The solder/connections... -
Re: New Members - please post your introductions here
My name is Pharaoh, and I work on electronics as a hobbyist. I am trying to learn more about electronics, motherboard repair, and soldering.
My soldering skills have improved greatly in the last year. I just bought a new soldering iron since my last one had broke, and it has been great.
Currently working on a PS2 slim 79001 which recently stopped powering on while swapping parts out for the disc drive.Leave a comment:
