Playstation 3 is no longer playing DVDs?

Since today suddenly can no longer play DVDs on my Playstation Slim. Yesterday everything still worked perfectly. When I insert a DVD, the typical start sound sounds. After a moment, another sound sounds as if the console wanted to eject the DVD, but it remains in the device. After that, nothing happens anymore. Games and Blu-Rays are running. I've already tried to vent it with console, set up the HDMI port again and tried the recovery menu number 2 (restore default settings) and 3 (database rebuild). Unfortunately, all without success. Maybe someone else has a suggestion for me?

CAREFULLY clean the laser. Please look on the net (YouTube) how to do it right.
