Hello,
Please, if anybody could point out an alternative 3.3V point (Other than the one posted) for the 75004 GH-041-34 EURO PAL PS-2 PCB.
I?m trying to install the Modbo 750 1.82 mod chip.
I just can?t stick the wire here!
Any help will be highly appreciated.
Thanks in advance.

Hmm, have you tried following the track on the PCB and see if you can find a 3.3V spot? Don't forget to check this with a multimeter before you solder it though. Also make sure you have a good quality soldering iron, as it's one of the keys to a success install :)

What I found weird is that I measured the continuity of the bottom part of the standard 3.3V point (The one I posted) and it is connected to the Ground!
The top part (metal) however is too worn, and I can?t check the continuity to any other point, neither can I solder the wire on to it.

you might have to scrape off the surface a little bit, and apply flux before soldering on to it.

Well, I burned off the top metal part of the original posted 3.3V point, but the component it self is intact.
Could any other problems arise from that now?
So, I'll need another alternative 3.3V point on the PCB.
However, after a closer inspection of the DMS4SE and the H2O diagrams, I noticed two alternative 3.3V points:
DMS 3.3V point:
H2O 3V point:
Also, I was told at another forum that the three smaller, brownish components above the 3.3v point I posted; the sides facing the 3.3v point also get 3.3v and can be used to find alternate 3.3v points.
But I can?t measure the continuity of these alternative 3.3V points with the original posted 3.3V point, as the top metal part is burned off.
So, any suggestions?
Thanks in advance.

I used a multimeter and checked the continuity of these 3 yellow highlighted points
As well as the pad above J point on the DMS diagram, but they all connect to the ground!
The DMS diagram states this specific pad above the J point as 3.3V for the V14 GH-040-12 model. But, there is a chance that on my GH-041-34 model, this point is different. Could anybody check the continuity of this specific pad over J for the GH-041-34 model and verify if it actually connects to the original 3.3V A point.
As for the other H2O power source, I can?t check the continuity to the original 3.3V point since the top metal is worn off. But, I would imagine its only 3V, as The PS-2 boots and the mod chip menu can be accessed, but neither original nor copied games will work!

Is the GND pad continuous with other grounds? Also the light green/blue is a conductor on the board, the dark is an insulator. It has a coating which can be removed. By the pic that you first posted, a connection could be made to the three components right above the original power source. What do you mean by the top metal is worn off? The metal should be a sort of end cap that the component uses to make an electrical connection between two areas of the board. Could you give a link to the install diagrams you are using.
