Completely satisfied by small artisanal intervention on the fan

I have the home theater system BDV E4100 Sony in electric giant bought and was initially disappointed because the fan ziehmlich the Bluray player was extremely loud and annoying. He has produced a very high whirring, which came close to a tinnitus.
But since I could not be bothered to pack everything again and to return again, I have made the search for the cause of the noise. That was the noise from the fan came ziehmlich quickly realized I was interested then but if the problem is the fan itself or the nature of the attachment is and I have come to the conclusion that it is really on the way of securing the fan, this is not how it screwed actually expected at all 4 corners on the housing but only on the bottom left and top right, the other two corners are hooked only to a small, bent metal tab (see picture) and exactly at this tab, the fan starts during operation at vibrate which creates this high whirring. I simply easily solved the two screws, so that I could do the fan when installed something, so that it is no longer applied directly to the metal shackles. So I was able to fix the problem, can certainly be applied to other Sony Bluray player with this fan problem.

Structurally sound and the system in my opinion is very good.
The only thing I miss in this system, a decent equalizer is to be able to adjust the sound to meet your exact, I might have these also simply not yet found.
The system is connected to a 47 "Sony TV and both communicates thanks ARC wonderfully with each other. Here, there are again a small flaw. If the TV and the system are turned off and you both turned on via the remote control of the Blu-ray player, then recognizes the TV that is immediately connected system and turn off the TV speakers and switches to the home theater system, this process takes but a whopping 31 seconds, as long as there is dead silence.
If one switches to the home theater system during operation of TV speakers is not but still takes as long as no less than 8 seconds, and that is in my opinion much too long, but do not know how the other plants is because this here is my first one.
That could indeed accelerate with a setting on Bluray player, then the player is running in standby mode and consume more power, at least according to the information when first setting up the plant.

Short Conclusion:
Positives:
-Easy setup
-Good sound
-for this price range (329) very good optics
-Comfortable communication with peripherals
-unkompliziertes pairing with Bluetooth devices

Negative (and therefore a star deduction):
-fan Without own intervention unbearably loud (I do not get myself fixed the problem would have, I would have the facility repelled again)
-very long switching from TV speakers to the home theater system

Certainly, the player also has ample Internet features that I'm here but not one that I have the same features and more on my TV and use from there.

CAUTION:
Meanwhile my fan hums loudly again, but am still at a solution to the problem off.
