No files found (video, audio, photo)

Hi,
I have serviio 1.3.1 installed on a raspberry pi and it works great on my tablet (except for subtitles) but on my samsung es5500 it doesn't show any files for all media types. And after trying for sometime it will simply give a message saying the device is disconnected.
It should't be a TV problem as it works fine with minidlna. I've search the detailed log but I didn't find any message which would give me a clue.
I attached an excerpt from the log file which contains the messages of the tv connection.
I know there are lots of similar posts but I've already read all these posts below and they weren't of any help:

Can anyone give me a help?
