Brokened PS2

Okay, so, here's the deal. My PS2 cannot read discs. At all. I purchased Suikoden IV three days ago. It has been out of my PS2 only once since then, so I could try another disc. It's basically in mint condition, fresh out of the box and right into the PS2. Same with the other disc, which I should mention was a music disc. The PS2 can't read either disc. Nonetheless, I repeatedly get disc read errors. Intially, if I left the PS2 alone a while and tried again, I could load the disc (after a couple reboots.) That no longer works. I'm going to run out and get some compressed air to try to clean the lens. Anyone know anything else I should try?

>>17 and >>19 speak truth.

Sony tends to use plastic springs for all their CD/DVD electronics. Unlike steel, these things degrade rather quickly, so eventually the lens is unable to focus.

It's not just for their playstations either. If it has moving parts and a Sony label, stay away. They've been coasting on their reputation for years.
