MI laser/disc spin problem on V5
My first install, I put a Matrix Infinity in my V5 PS2. Now, I still have power, but the DVD drive doesn't spin. Well, it does a quarter turn when the power comes on, but that's it. No discs will boot, either originals or copies. The laser doesn't come on at all. I still get the initial PS2 start screen, and then it goes to the Browser/Configuration screen, as if no disc has been put in.
I can get into the MI menu OK and I can disable the chip, but disabling the chip makes no difference. I've double checked my solder points and they look OK. One thing though, the U conductor point on the MI came off - I stuck it back down with solder - will this work or is it screwed?
Any ideas? Have I killed the laser? Everything worked fine before the chip install.
