My PS2 can´t read DVD-Games

[Ernieboy0021]

Since todays my ps2 can´t read DVD anymore. Theres no problem with cd based games, and ps one games.

I tried to adjust the lense based on Internet Documents ("How do I....") It´s a V4 machine an i tried the correct FAQ Files. But it still don´t works.

I tried many different positions of the lense but there´s always a knocking sound of the drive. 3 or 5 times knocking.

Could it be a lense problem if it takes only CD based games or not?

I tried every single position of the wheel at the back of the drive this didn´t work as well.

Now I haven´t got any ideas anymore and I hope you can give me some advice.
