    Modding a V9 PS2 for a friend at work and I'm a bit stumped.
    The specs are V9 with a GH-023 motherboard, a modbo 4.0 chip

    I can remove the chip and get video and audio at the sony browser. With the chip installed with power, reset, cx, and all bios points, it will immediately return the system to standby upon power up. I have checked and there are no bridges using the continuity setting on the multimeter.

    Any idea on how I am screwing this up?

    Scratch that. I somehow cleared up that problem with the chip bios active and going to the browser. Going to keep this thread in case I do need help going after the rest of the wires when I can get a chance.

    OK, got the chip installed and 100% functional. That includes the Romeo mod on that board. There is one last thing that is driving me nuts about it. When ejecting or loading a game, the laser eye jumps around like crazy creating an almost grinding noise. What could be the cause of that? It didn't do it before modding, so I know it is something I've done.

    If you have camera, show me a close up of your install points, and overview shot.

    Could be issue of where you taking the power and ground from, with all the motors running for eject and loading, sounds like the electric magnets are getting power spikes or drains from modbo eating up too much current, leaving not enough for laser and motors to operate.

    Sorry they are not high quality. My cell phone is the best camera I have. And I really do appreciate the help.

    Disregard the V9. I scrapped it. Picked up a V7 with a GH-022 board and the install went like a dream on the first go. Enjoy the pics of the last chip install I will ever do on a PS2.

    Also used the fan from the v9 to make the v7 quieter.

    Yeah, i love the v7 it was the most stable and longest lasting version of all the PS2's out there.

    V9/V10 always endup with laser problems, and V4/V5 always had problems with over heating.

    And well whom wants those early v1/v2/v3 systems, most of them are dead by now anyway.

    And v12 and above are all those crappy slims, with them getting even more crappy later on by v16 with the sound chip changes, some older games will not even play correctly anymore.

    So good choice for your mod install using a v7.

    One thing I found weird about this v7. It actually had an HD7 laser in it. Tripped me out since I know that the v7 and even most v9/10 had the KHS-400C lasers.

    And I agree the V7 is the best version PS2. I only wish it came stock with a built in IR and the v9/10 fan. It would be perfect.
