Ever since i installed my flip-top my lens has been acting up a little. When the game loads sometimes it makes this noise when the lens is moving. As of recently, my NCAA College Football 2005 has not been working. I will start a game but it always freezes in the first quarter. When i put my SMD in sometimes i have to restart my ps2 once or twice before it actually loads up. None of my cd based games work so i know that the cd part of my laser is done with. So should i just invest in a new laser or can this be fixed? Where is a good site to buy replacement lasers?
