Oh dear it doesnt work...

You have got something downstream of this to provide power? Some
multiswitches default to vertical low-band on outputs which aren't
getting any line-power, while others give no (or greatly attenuated)
SAT o/p on unpowered output ports.

Most quattro LNBs only need one output to be powered to provide all four
output signals, but you find some that need each output to be separately
powered.

Anyway, check that power is getting to where it should before going too
much further.

The meters backlight lights on all 4 feeds from the dish, so that would
indicate to me the MS is providing power to all feeds. The unit indicates it
provides 13v and 17v on the feeds.

So the m/switch is powering the LNB OK. What about power from the sat
receiver(s) to the m/switch output(s)?

Yes I have that also...Have tried two boxes.

It appears the issue is either a duff lnb, a duff MS an alignment issue, or
insufficient signal making it to the MS.

LNB cables connected to the correct inputs of the switch?

Getting what looks like a very good signal on a meter such as the slx
can mean very little

In my limited experience, it seems at times that it is possible to get
an initial spurrious strong signal registering on a satfinder meter when the dish
is elevated at completely the wrong angle (maybe something like 40+ degrees
instead of something in the range 25 - 35 degrees).

So always set the elevation accurately first. And remember that until
everything is fully tightened up, there will be a tendency for the dish
to sag a few degrees downwards.

Then rotate the dish towards the appropriate satellite cluster whose
direction can be ascertained relative to immediately local objects
using

http://www.dishpointer.COM

then fine tune with the meter, gradually turning down the gain.

Finally adjust the skew of the LNB from the vertical as appropriate,
checking on both the signal strength and SNR back on the receiver
and TV/monitor screen.

Sounds like you're on the wrong satellite. When the weather picks up try
the ones on either side on the one you're on now. As for it 'looking
right' I have three dishes in a row here on three different satellites
and you can't tell.

Sorted:

a) Dish was on the wrong satallite
b) One Quadplexer outlet was faulty!

HI

thanks for letting us know. Dish setting gets much easier with
practice, once you 'get on the arc' east of south it's no too hard to
work out which one 28E is. You do need something to measure quality to
set ths skew correctly.
Well done
