Conversion of the satellite system - Quad to Quattro LNB

Hello dear forum,

I am currently stuck and need your support.

Situation:
I have replaced the existing satellite system (Quad LNB + splitter + DVB-S receiver) with the following new configuration. I now have the SCHWAIGER "SUN PROTECT - Digital Quattro LNB", Kathrein "EXR-158 Multiswitch 5 to 8" installed with the DVB-S2 receiver built into the TV. The satellite reflector and the terrestrial antenna as well as their positions have remained unchanged. Cables and connectors have been completely renewed and checked (everything is fine).
Although now (according to my understanding) everything is correctly connected, "actually" everything should work, but nothing. The TV receives no signal at all, neither from the antenna nor from the satellite system.

Question: What am I overlooking?

Regards,

For me, it was the SAT cables. After reinstalling the LNB, etc., it simply didn't work anymore. I then switched all the TVs to internet reception. In the kitchen, it still works with a single LNB. Presumably, the SAT cables were outdated or of poor quality on your side.

But actually, I don't need Sat anymore. Everything now runs via WLAN. It's also better.

Why was it the SAT cables for you? I also had them newly installed during the renovation, this "should" not be the problem.

Since the LNB was replaced, the dish may have shifted slightly or the LNB is not positioned correctly; the distance is now different, it is slightly rotated and therefore not installed like the old LNB.

If you don't have a Sat Finder, get one. Costs about 10 euros.

Have you connected the cables coming from the LNB to the correct inputs of the multiswitch?

Have you made sure that no wire of the shielding accidentally touches the center conductor?

I assume the multiswitch is connected to a working power outlet.

Have you done a new channel scan on the TV with the correct settings?
