Could anybody explain the following in plain English please.

The new LNB is not due until Monday or Tuesday. I was idly choosing
programme numbers on the Freesat PVR at random this morning and when I
put in 170 I got picture and sound on a channel that identified itself
as "Quest Red +1".

So I looked up the "Signal Information" screen and it said:
SIGNAL 1
NETWORK 003b
TRANSPORT 07F3
STRENGTH 75%
QUALITY 60%
LOCK Yes
SIGNAL 2
NETWORK 003b
TRANSPORT 090b
STRENGTH 75%
QUALITY 0%
LOCK Yes

Then I changed to Channel 106 (BBC1 HD) and got:
SIGNAL 1
NETWORK
TRANSPORT
STRENGTH 0%
QUALITY 0%
LOCK No
SIGNAL 2
NETWORK 003b
TRANSPORT 090b
STRENGTH 75%
QUALITY 0%
LOCK Yes

Other than deducing that no Signal 1 means "No Signal" displayed on
screen, the information means nothing to me. I am hoping someone can
explain the above.

My TV has an F connector I have never used (I have always used Freeview
on the TV), so I connected one of the satellite downleads to it and
asked for an autotune of the satellite (Astra 28.2, it said as it
tuned). It gave me just 48 stations, and as I browsed through them
afterwards I found that one of them (numbered 34!) was Quest Red +1, so
it looks as though it had found the channels that were coming through on
the PVR but not the ones that didn't.

With the downlink connected again to the PVR I did a bit more
experimenting. Channels 101 to 125 were all "No Signal". Every channel
I tried at random above 125 did have a picture, though a few of them
pixellated occasionally.

Curiouser and curiouser.

The receive can switch the LNB between receiving Horizontal and Vertical
channels. It can also switch the LNB between receiving higher or lower
frequencies.

Sometimes LNBs fail in a way that stops them receiving channels in one
or two of these quadrants.

Thanks for the channel details.

I haven't done a proper check, but the channels I remember working are
all in the higher frequencies, but I didn't have a big enough mental
sample to decide whether it was all the lower frequencies missing or
just the Horizontal.

It looks as though a replacement LNB might be all I need.

I think the technical term for this condition is buggered.. ahem..

So how does the lnb actually change its polarity. Does this actually mean
polarity or is it more like a corkscrew left or right in reality?

The receiving aerials in the LNB consist of two pins sticking into a
circular aperture though which the dish reflects the signal. One protrudes
at the 12 o'clock position and the other at the 9 o'clock position. Those
pins act as antennas and are sensitive either to vertically polarised or
horizontally polarised signals.

Though there are other types of LNB (i.e not so-called universal type)
which use clock/anticlock circular polarisation.
