Hi, I just installed a flip top cover on my ps2 yesterday and when I tried it out this morning it plays the games fine but then after a little while the dvd starts making funny noises like it fell off the spindle. I replaced the white thing on the top with the old white thing because the new one didn't have a magnet in it. I thought the one with the magnet would hold it in place better but it still falls off. What should I do? How do I fix it?
