I'm receiving no signal on my Humax/Manhattan box
Extreme weather conditions (such as driving rain, strong winds or snow) can affect the satellite signal.
In the event of calm weather and your Freesat box or TV reporting no signal there are a few steps you can take to try and resolve it.
First, make sure all the connections at the back of the box/TV to the dish are securely tightened; then try doing a channel scan, or first time install to see if this restores any lost channels.
In the event that this doesn't resolve the issue, there may be a problem with either the alignment of the dish, or some interference in the LNB (the protrusion at the end of the dish that the wires connect to). If this is the case, then you might need to contact an installer to come and look at your satellite.
