To get the green motor light to show up you would probably need to alter your settings. Try to keep it simple, and just connect the cable, from your LNB, directly to your receiver.
You can use your tecnomate to ensure the LNB, and cable, are working, by connecting it to that first.
Once you know this is working you can connect it to your VU+, ensure the tuner is configured correctly, and try scanning in some channels.
