Problems with Infinity install in a NTSC v2 board GH-004

[Nightman]

I am installing an Infinity in a friends ps2 NTSC v2 with board revision GH-004. I am attaching a picture to show what my problem is. There is a chip that has been moved by sony, and the place they put it is the same place that the instructions show to solder wires to. I soldered the wires to the leg of the chip, and when I try to boot the ps2 all it does is it turns on, no video, the dvd drive makes a quick grinding sound and it will not eject. The blue light on the eject button flashes constantly after I press it, and it does not stop until I turn the power switch off. Anyhow, any Ideas? This ps2 has been refurbished by Sony, and it was working perfectly fine before i started modding it. I think Sony put the chip in the other spot when they refurbished the ps2.

If that is the case, then I would assume the orientation of the chip has changed. In that case, reverse the points (IE P goes Q, O goes to T, etc). It sounds a little half assed, but it's worth a try.

Or better yet, take a look at diagrams for other chips; chances are the BIOS points are more or less the same. Take a look at this DUO diagram for instance.

well, I completely uninstalled the chip, and the ps2 works as it did before. That tells me that the board configuration has changed. I'm lost....

Here is a picture of the actual board that I am working on. Chip marked X is supposed to be in the spot marked O according to the Matrix Teams install photos

Here you go. This DUO diagram is very similar (if not exactly the same) as the picture you just posted. These points should work with the Infinity as well.

That pic looks just like a V1 I had (preordered console when PS2 first came out). My BIOS chip was in the same position, contrary to the pics of Team Matrix. You should be able to wire to the same points regardless. Did you use a multimeter to check continuity for each wire?

Update!!

I completely uninstalled the chip along with all wires. I just got done re-installing it after I got a response through email from Luke of the Matrix Team. He confirmed that I had a version 2, but they put a gap bios in it when they refurbished it. He said I did it correctly by soldering the wires to the specified points, even if the bios chip was in place. So I re-installed, and wa lah!!! Works great, and this old v2 even boots DVD+R discs!! WOOT!!!
