My Blaupunkt TV is both Netflix and YouTube, etc., but unfortunately, no signal is displayed after each channel search.

I have already tried a lot, can someone help me?

How do you receive cable, Sat or DVB-T2?

Which tuner did you set for the station search?

Satellite, and what exactly is a tuner? Sorry I know zero with TVs.
