I have seen the occasional unexplained circular pattern of scratching which
_might_ indicate the lens hit the disc. From a technical standpoint, this
seems nearly impossible, since the lens would have to push up about another
2 or 3mm. If the drive IC "rails out" I suppose it's possible.

Too much cleaning can ruin the CD player's lens. If it goes blind

You shouldn't post when you haven't the slightest ****ing clue about the

You shouldn't post, period.

Having the lens hit the CD is a problem in some players. The player
looses tracking, the linear focusing motor relaxes, and the lens bounces
undamped. Sony electronics are often marginal or poor in quality so I'd
suspect that it's one that can do it. The poster mentioned frequent
cleaning, which isn't a great idea.
