I've recently soldered on a Crystal Chip 2.0 PRO SLE on my V7 PS2. I'm having trouble getting it to boot up now... I've burnt a cd with the FW on it, but whenever I turn the ps2 on, the tv just goes black (not no signal, but black) and there is no sound. The lights come on, and the drive spins up, but no output at all. I looked at the chip, and the led blinks once on startup, indicating that the bios wires are correctly installed i think... Any suggestions on where to start looking for a problem?? Thanks for the help!
