V7 Modbo modchip installation diagram

One of the revisions of the fat PlayStation 2 was the V7. They were found in many of the SCPH-3900x models. Matching console model numbers and board numbers are listed below.

I sell Modbo 5.0 modchips in my store.

You can find the model number on the sticker on the bottom of the console, and the board number is printed on the PS2 main board if you take apart your console. Note that there can be multiple board numbers within a specific model number.

  • NTSC-J (Japan):
    • SCPH-37000 (GH-019, GH-022)
    • SCPH-39000 (GH-019, GH-022)
    • SCPH-39006 (GH-019, GH-022)
    • SCPH-39007 (GH-019, GH-022)
    • SCPH-39008 (GH-019, GH-022)
  • NTSC-U/C (United States)
    • SCPH-39001 (GH-019, Gh-022)
  • PAL
    • SCPH-39002 (GH-019, GH-022)
    • SCPH-39003 (GH-019, GH-022)
    • SCPH-39004 (GH-019, GH-022)

Note that there are multiple versions of the Modbo modchips available, but the installation diagrams are all the same. Some example versions are Modbo 3.0, Modbo 4.0, Modbo 5.0, and Modbo 750.

Installation tips

Here are some tips I have for you when you are soldering your chip into a V7.

  • Using 30 AWG solid core wire works well for most of the points.
  • Use some thicker wire for the 5V and ground wires.

This first one is a GH-019 board (click on the image and then zoom in to see the details). There is some solder on some additional points because I removed an older modchip and replaced it with a Modbo 5.0 on this board.

This second one is a GH-022 board (click on the image and then zoom in to see the details). You can see that even though the BIOS chip has a gap in the pins the wiring is the same.

Did you bridge the caps at point SX? is this required as the track leads through both.

Installed Modbo 5 on two PAL SCPH-39003 (GH-022) model PS2s and PS2 disc backups wouldn’t boot without the ‘H’ wire attached. So despite the instructions above, I had to include it.

Unsure if this is a difference between Modbo 4 and 5 but worth noting.

I had this too, PS2 thinks some backups are DVD Video and others it point blank refuses to load them. So are we saying that point H IS required?

Thanks, the system is PAL but the games are NTSC. Defiantly needs the H?

Hi, I picked up a modbo 735(branded as infinity 1.99) for a scph 39004( pal) version. Will the diagram above apply to this modchip as well?

i just installed Modbo 5 on a Pal 39004 system but there is no modbo boot up it just look like the regular ps2 boot up screen. What do you think could be at fault here?

Hey William, thanks for replying. I’ve tested continuity and I get continuity beeps. Maybe I’ll start over though..

Also, SX is bridged on some pictures I see, I mean bridge the resistor and the capacitor and solder the wire in between. I dont have that right now. Is that needed? Model is 39004 gh-019

Okay great. I’ll leave it as it is. Still not seeing anything when starting the PS2. Do you have tips to verify whether something is connected in the proper way? Because to be honest I don’t see anything that I can do at this point.

Hey! I also have trouble with this mod, everything is connected but no mod menu or logo. Oh and I hate those ribbon cables, looking at them damages them.

Possible to test the mod chip? I suspect its bad

Well the new modchip did the trick, finally saw the matrix menu. Powered down because I had to connect the memory card/controller station. In doing so, after having taken it apart 20 times without issues, the PSU shocked me. After doing that all I get is a black screen now. ****. I appreciate the help you’ve given so far, do you think it’s dead? I would start all over with the mod chip but I think I would at least get a video signal right? The TV does detect the ps2 upon switching it on, because it will switch to… Read more »

Hi, i did the mod as shown and get the „Matrix“ logo when power on but the disc drive does not start to spin. Eject and close are working. With an original disc in it the white thing thing on top of the drive (when the PS2 is not closed) makes a little move (0,5 cm) and then stops. You think it is a problem on the board or from the flex cables? If i have to remove the mod chip i would never again install it. Took me four evenings to install and five years of my life as… Read more »

Hi, thank you for the fast response. I fixed it. The motor cable was not properly connected. The PS2 now reads original discs as before but no so the backups. Maybe this is an issue of the „H“ connection as my PS2 is a PAL-one and there are different opinions if connecting it or not. But that is not a big deal as i would not use backups at all. It was only a soldering project for me and now i have enough soldered for the next ten years 🙂 For beginners i would recommend not using the same position… Read more »

Hey there, can I use the pad on the top instead of the bottom pad for the CX line? I used my thicker wire on accident and removed the bottom pad.

Would it be safe to use AWG 30 wire for all points including 5G and ground, and if not what AWG wire should I use for 5G and ground?

Hello again, I have accidentally burnt the pad off on the ps2 motherboard for the Q wire, have I broken the board and if not is there an alternative point on the board to solder to?

Hello, I have had a curious problem installing modbo 5.0 on a 39001 NTSC U/C PS2. Matrix logo apears and after it shows “Loading boot_menu v.1.00…” and it remains on this screen forever. As I can see you really knows a lot about this chip, do you have any ideia if it is a incompatibility of this chip with this specific Ps2 model? I have tried 3 modbo 5.0 and no success until now. Many Thanks in advance for any type of advice.

So, I appreciate your fast reply, but I discovered the problem was not with installing the chip. This particular model did not work without one controller connected (at least this one I metioned). I have already installed modbo 5.0 in other slim ps2 and this situation does not occur like this one. That said, the curious solution to this issue was that.

I have just installed a modbo 5.0 and now my console just shows a black screen + there is no blue led light at all. I’m pretty sure I did everything right… but I have a couple of questions. Do I need to cover the mod chip with insulation tape to stop it shorting? Also am I right in saying the SX wire has to be bridged between the two points as that’s what it looks like in the picture so that’s what I did?

Any help is really appreciated.

The connecting pad where G connects to got ripped off. Is there any other other places where that could connect to (or diagrams for the console)?

Hi, SCPH-39004 here and i’m using the Modbo 5.0.
In the diagram it says to leave H out for PAL consoles but for mine it gave a mulfunction error while booting the game. It worked after i connected the H pin.
Idk if it’s a thing just for me but if you have the same problem it might be that.

Hey there, I installed the modbo 5 on a scph-39001. When I turn on the PS2 the power button works but the eject button does not open the disk tray or light up but it does turn on the PS2 if I press it but nothing else. The disk tray also is not spinning. Would this have to do with the chip or with the ribbon cables?

Thanks, I’m going to try to figure out if I need to replace it or just insert it all the way then.
