I got a brand new ps2 last week and for the first few days it worked flawlessly. Now it makes a very fast ticking sound that seems to occur whenever the laser is reading something. When the laser is in the process of moving, the sound doesn't happen. It's sort of like a much quieter version of the sound you would get from putting a playing card between the spokes of your bike wheel. So far it hasn't affected my ps2's ability to read discs, but I'm worried about what it could lead to. Any ideas? I'm thinking about sending it back to sony since it's only a week old.
