Argh! MI booted, now it doesn't
Argh! MI booted, now it doesn't –
I got a Matrix Infinity today, and soldered it onto the motherboard of my PS2. Before I put it back together, I plugged the power supply into the motherboard, and plugged in the gamepad header and reset/eject button. I connected to the TV and booted up. I got the Matrix splash screen, and I could go into the Matrix config screen. Of course I couldn't boot any disks without the DVD/CD drive.
After I put the motherboard shielding back on and connected the drive, I tried booting again. Now I can't get the Matrix splash screen or config screen. It boots originals and everything like it should, but no Matrix.
I took it apart and checked all the wiring, and everything looks good. I used an ohmmeter and verified that there's a good connection between each solder point on the MI and it's corresponding solder point on the PS2. But the chip doesn't do anything now!
What else should I try?
Is It A Real Matrix And Did You Change Anything In The Config Menu
Yes, it's a real Matrix (bought it from NetMech). I don't think I changed anything in the config menu, but I may have run the cursor up and down in the menu to verify it worked, and changed something inadvertantly in the process.

no if its a real matrix then it should at least boot to config menu.
check all wires not at the joins but along thr wires and see if any got pinched when putting the unit back together, they could be shorting out because they got pinched
I don't see any visibly pinched wires, and the fact that the ohmmeter shows no resistance between the two ends of each wire suggests that they're not broken. Or could the ohmmeter show no resistance on a wire that's not connected enough for the matrix to work?

Reason: typo fix
why didnt u let netmech installed it for you?...he is a good pro installer.
just give each wire a little tug and make sure it is fully connected, yes the ohm meter will lie if your only touching each end of the wire, that is just telling you the wire isnt broken not that the wire is connected so check that and see how you go, check especially your B, G and I wires

I guess my next step will be to touch the solder points with the iron and re-melt the solder. Thanks for the tip about the B, G, and I wires. I'll start with those.
Edit: Actually, the G connection isn't used. This is a v7 PS2. I'm going by this diagram: http://www.infinitymod.com/matrix/fi...V08/USA-V7.JPG
