I just bought a fliptop for my PS2 V9 console and I followed the instructions and the flip top fits on top of the PS2 just fine, but when I put in a disc it gets VERY VERY loud. If I press down HARD on the flip top lid it sounds fine and works properly. I actually lost the case screws to the PS2, but it worked with that way with the original PS2 lid. Did I get a defective flip top lid? Please help!
