Aha! So put players from the open cabinet in the closed cabinet, use of course none, but still clearly hear sounds. After 2-3 months back problems with playback. Now a registered letter - friendly - to Samsung. No feedback. A further 2 months later, the player is almost nothing more again, even a registered letter, now with a deadline 4 weeks, at Samsung, response within the deadline, no. After another five weeks is a form of writing that I should send the device to TVS. For that I have taken the trouble to send a two-page letter to Samsung, with a request for clarification why the units are so loud. So back to the device still friendly Händer, return, after two weeks the device is there, built 3 new drive again. Test run, still loud.
Conclusion, the player is virtually no longer used, I'll sell it. A new course no longer comes from Samsung. Even a faint when buying equipment can still be loud after the Return Period.
Anyway, if you do to repair must submit.
