You're welcome and it's the reset/on and off switchJust got home from post office and school.
Looks like it's time to make an another one!

Thanks to @E64 !
I got the package today bro!
Btw, what's the wire for?

You don't need to use the 3.5v from the controller to reset/boot the PS2. There are 2 pads you can solder to that is better near the BGA DVD decoder.

Are you using composite video with this?You don't need to use the 3.5v from the controller to reset/boot the PS2. There are 2 pads you can solder to that is better near the BGA DVD decoder.

That particular board is but I'm not in my portable.
Is this the overall using the PMS?
p.s. I'm no sure about the CMOS battery, I think 7.4v is wrong to wire to the B+

I hope you haven't wired the pms yet, if you wire the battery in a 2s fashion to the PMS you will fry the power unit as it is meant to run in a 1s2p fashion. I don't know what trim you are using but the ps2 pms requires an advanced trim, I saw a photo of a standard trim but that looks like someone elses photo
the CMOS battery will be a 3v button cell, 7.4v or such will likely burn something you don't want to
1S2P? Does that mean that it should only run within the range of 3.7 ~ 4.2v?
and 2p, which means that the capacity will be doubled? since each battery is 3400 mAh, therefore 6800 mAh?
I don't see any 3v coming from the PS2 motherboard, will 3.5v be fine?
Yeah 1s is a single LiPo voltage, 2p is parallel so yes capacity is doubled.
The battery 3v is 3v, using higher voltage or lower is not recommended it's a real time clock chip which is why a 3v button cell 2032 battery is used for this. The only thing the battery effects is the moving logo on the main screen and keeping the time, this won't be able to be ran off of the ps2 PMS.
You can see my worklog of how the PS2 looks when running the PS2 PMS
Is it possible to use a Gameboy Volume Potentiometer to U-Amp?

It is not possible, no. The U-Amp uses digital volume control onlyIs it possible to use a Gameboy Volume Potentiometer to U-Amp?

I performed Standard Trim on my motherboard today.
After removing the filter capacitors which is those color gray
from this --->
into this --->
I tried testing it on an LCD if there would be at least a Composite Video output which I tried to tap in either of those two yellow circles base on the image above.
I have no video output
Have I missed something?
Do I have to connect 5v at least into this in order to have a video output?

So from the image that I can see of your trimmed mobo, I'd recommend double checking where your system voltage is coming in I'm assuming your 8.5v is that white wire, when I did the standard trim I had my 8.5v (and battery input) connected to this pad underneath, also white wire
The split white is going from there to the linear regulator on top, red wire is 5v side to the audio amp. If this regulator is getting the proper input voltage it will give 5v to the system including the video chip on the bottom of the board.
Then I took composite for testing from here
The other thing I'd recommend is give your board a dust off too there looks like a lot of fine particles on it. The other check is just make sure you can see a seperation in the board layers so there no short

I tested it today using a multitester
I found out that the right leg of the linear regulator is not outputting 5v, while the left leg which takes 8.5v is working perfectly.
Is it possible that the linear regulator is half-dead or only working in half?
or maybe because I removed these 2 capacitors?
I don't think that these capacitors affects in receiving the voltage of the 8-pin audio dac or the linear regulator.
I can't say what would make a linear reg half dead but if you're not getting 5v that would definitely cause the system to not work properly.
Those 2 capacitors that you circled are following the L/R audio channels from the amplifier to the original av port those won't affect power. That's why they are labeled with #4 and #2
I'm guessing you've already checked for shorts?
Too bad there won't be anymore PS2PMS 
Btw, I'm done with my work
It will be both my first time to have a 3D printed case and join a competition here for my next worklog

The PS2-PMS still exists on GMan's github, you could have a go at assembling one yourself if you have the confidence.

Could you send a picture of the other side of the board so I can see how it was connected? It's because I have a little doubt where to make the connection.
Just wanna share my 3 PS2p that I have here as of now
the black one on the left took me 5 days to finish
It was tiring
