Hier ist ein Link zu Sony, der weitere technische Details angibt: https://www.sony.ch/de/electronics/support/televisions-projectors-lcd-tvs/kdl-40we665/specifications

The device does not have an Android operating system, but Sony's own. Therefore, access to the PlayStore is not possible. This is only possible with devices with Android operating systems.

Whether it's junk I don't know, but I assume production has stopped as this is a 2017 model.

I did a quick google for you. Yes, the model has an ARC/HDMI connection.https://www.sony.com/electronics/support/res/manuals/4689/46896422M.pdf Page 167

Yes, there is a button on the remote control

Yes, the remote control is equipped with separate buttons for YouTube and Netflix.

In Ejul, I think not, because there is no bluetooth function.

Yes it is Smart TV but beware: there are only a few basic applications available and it is not possible to download additional applications because no Google Play is available.

Simple but functional remote control. A network cable is not included.

Yes, that works wonderfully. Of course, you can then only watch the normal digital TV channels (and radio channels) and neither the browser nor Netflix etc. can be used.

Hello Dr3do. Unfortunately I can't answer that, but I would try Digitec customer service!
