I have a SCPH-30001 R Mobo GH-022 PS2 that had a bad laser. I used an ocelloscope to adjust the laser and fried the motherboard. It turned on but the eject light didnt light up and no laser movement and no picture.
I Just bought another PS2 from a friend which was missing parts but he claimed that the mobo and laser worked. I swapped the mobo into the other case and hooked it all up, laser swapped too and same problem. Eject light doesnt light up, no picture and no laser movement. Motherboard was a GH-015 with the model number SCPH-30001 R
I have isolated the motherboard, Powersupply, motherboard, heatsync, and tried to turn it on. Same problem.
Now did my friend just sell me a PS2 with a broken motherboard or am I doing something wrong?

I just had this same problem.
Eject light wouldn't light up, only noise was the fan. No movement at all from the laser.
I had a blown PS14 fuse. (my ps2 with a v7/8)
I could be possible that something is making this fuse blow. And it made it blow on your new motherboard too.
Check ALL your fuses with a ohm meter and look for continuity. If you have continuity, the fuse is good.
This link is from another forum, but has all the fuse diagrams in the first thread post.

Let us know after checking the fuses.

In my case it looks like a blown PS11 fuse. I checked it with a connectivity tester. Im gonna try to place a piece of solder on it or bypass it and see how it goes.

That didn't work, it just smoked. More tests showed the one of the voltage regulators by the PS11 fuse was missing. Its not worth fixing it anymore. The things are too close together and die when heat is applied.

It was only missing on one of them but when I attempted to take it off the other it didn't come off correctly and it was too hard to solder it back on due to the size. Do you want the motherboard?

Any chance you can post a pic of motherboard with the piece that's missing circled?

This is not a picture of my motherboard
But I can tell you that the part by the top left, next to the controller ports has the fuse and brown regulator. The regulator is missing and the fuse is blown. Im gonna try to solder it in with wires, it may be easier.

Ok, here's mine. It still smokes after I have replaced that regulator, seen with wires. Should I also try to replace the fuse? I would think that solder over it should be fine.

Hmmm...dunno if you want to bypass the fuse...you can try it though. Just solder a wire to each end of it and it's bypassed.

Did that, it turned on for a second, saw the blue eject light and smoked and the light turned off. If I let it sit and did it again, it would do the same thing numerous times. I then put a fuse there and it instantly blew the fuse. I think the motherboard is trashed. Something is making it fuse instantly which I cannot determine.

core2kid, was the unit working BEFORE you changed the settings or replaced the laser/mobo? If you forgot to remove the static points, or maybe turned it on with laser ribbon loose/not connected, one of these may be the problem. Re-trace what you did.

Heres what happened from the beginning.
PS2 with DRE. Opened it and tried the "quick fix" of turning the white knob and it didn't work. Tried every option. After that I took apart the PS2 and tried the oscelloscope fix. When doing that I turned it on with only heatsync and motherboard and touched the GROUND end of the oscelloscope to the edge of the motherboard. As soon as I did that it shorted out. I then bought another PS2 from a friend who claimed that it worked. That was broken, the motherboard didnt work. I took that apart to find the voltage regulator missing and the PS9 fuse blown. Attempting to fix that did nothing. I still never found which fuse was blown on the motherboard that shorted out with the oscelloscope.
