I have installed a CC2.0 on two seperate v9 ps2's, and in both cases the ps2 will not display any video, however, the cd spins up. I have checked all connections with a multimeter and looked for shorts. I have even scraped the solder mask off of the traces connected to each solder point to check for conductivity. The diagnostic led stays green after powerup, as if the bios connections are wrong, but like I said, I have checked them repeatedly. I wondered if anyone has had similar problems or suggestions as to how to fix it. I am actually wondering if the chip itself is bad, but that seems unlikely given that they are tested at the factory. I also note that the installation diagram has a section marked "alternative"; I installed these, but I wondered if I shouldn't have.
Any help would be most appreciated.
