Hoi @thomascheimarios ,
Wil je het volgende eens proberen?:
1/ Zorg dat er bij de ontvanger of antenne geen externe storingsbronnen staan in de directe omgeving. Denk dan aan b.v .een modem, LED-lamp of DAB+-radio.
2/ Haal de ontvanger even vijf seconden volledig van de stroom af.
3/ Zet de antenne op een mooie hoge plek.
4/ Zet de ontvanger (en TV) weer aan.
5/ Ga in het menu terug naar de fabrieksinstellingen.
6/ Geef een nieuwe opdracht zenders zoeken, maar dan via de optie uitgebreid zenders zoeken.
7/ Draai de antenne eventueel een beetje bij aan de hand van signaalmeter uit het menu.
Would you like to try the following ?:
1 / Make sure that there are no external sources of interference near the receiver or antenna. Think, for example, of a modem, LED lamp or DAB + radio.
2 / Disconnect the receiver completely for five seconds.
3 / Place the antenna in a nice high spot.
4 / Switch the receiver (and TV) back on.
5 / Return to factory settings in the menu.
6 / Give a new search for channels, but then via the advanced search channels option.
7 / If necessary, adjust the antenna slightly using the signal meter in the menu.
Hi Thomas, welcome on our board.
Did you try the tips given by Noordzee?
Let us know.
@Alex_P , Thank for your replies.
Had already tried all of the above without any success. That's why I posted on the forum.
Then a couple of hours later the signal was restored. I suppose there was something with the signal in the area.
Good that it works again! 
The restore of the signal could take some time.

I'm glad everything works well now. You know where to find me if necessary.
