Let us now, however, to the dark side (the reason why I can only awarded 3 stars here): I'm using the built-in DVB-S receiver. With many programs (PULS4, Pro7, SAT1, Kabel 1) you can hear a durable, very annoying high Fiepgeräusch (on the back of the TV right - near SAT connection / CI module slot). The sound is always audible. If you switch to another program (eg RTL), the noise is gone. If you switch back to an above-mentioned channel, it's back. A similar sound is heard after turning off the TV (here interrupted in part, in different "pitches" - after 5 minutes here then rest). However, a no-go when you are on the TV in the bedroom, for example, and want to sleep the way.
Even if you watch TV at night with low volume is extremely disturbing.
After consultation with the Sony support I will probably bring the unit to an on-site repair service. The outcome of the repair I will publish here.
UPDATE
Today, the television came back from the repair. Situated, turned, whimpering was back. I then took me the tip of another user to heart and asked the LNB voltage when manually tuning on 14/19 and again carried out the tuning. Since then, no more buzzing!
