Ok, so I bought a Magic 3.6 and am getting read to install it. I figured I had better get the disassemby mastered first, so I took it apart and put it back together. After I put it back together the PS2 won't read discs. It recognizes memory cards, boots up to the browser, even recognizes a disc is inserted, but keeps on saying "Reading Disc." I checked the cables are all replaced properly. I have a V7. Any suggestions?
