Ok i had a v7 ps2. That ps2 broke(long story) anyway my cosuin gave me his old ps2 cause he got a new one. The problem with his was that the disk drive wouldn't open. I thought i would just attach the fliptop i had on my old v7 ps2 to the other one my cousin gave me(don't know what version it is) and probelm solved. But when i put a disk in the system it spins out of control,you can hear lots of screeching noises from the laser,and the disk will spin off track. How do i fix this?? None of the disks will spin correctly it always go off track and the laser make these loud screeching noises.
