Matrix Infinity, no video output in v10
I installed a Matrix Infinity in a v10 NTSC PS2. I get no video with the chip in. I can eject the drive, reset, etc, but have no video output at all.
I checked the BIOS P, O, N, M with a multimeter and there appear to be no bridges between them and the pins on either side, same with Q, U, T, V, R, W. No bridging found.
All other points look good as well. Y wire is wrapped with another and that wire is grounded.
Any possible points I should double check? Is it possible I got a bad chip?
