Hi there,

I'm helping my mother in law with her freeview woes.

The guts of it is she said that some of the channels don't work anymore - ONE and TV2 at least. Other channels like TV3 and Shine work fine.

Signal on the box is showing 80%. When I checked the channels that aren't working, it seems to be those on Optus D1 Carrier1_s4. My MiL lives in a reasonably tree rich area and I had to prune a tree to get any signal at all. There is some regrowth on said tree now.

I'm a bit of a newb with this sort of thing. I would have thought 80% would give me all the channels no hassle etc.



thanks
N

What type of box are you using?

Trees shouldn't make such of a difference for satellite unless the dish is completely blocked, but even then if you're getting a signal off a single MUX you should get everything.

iirc, it's a reasonably aged DVS model one.

What you said is what I would have thought also. I don't have the luxury of testing with a different unit, unfortunately.

Try skewing the LNB, The Channels on 12483 will be the first to go if not skewed correctly.

Fro ma quick Google, that involves rotating the LNB in place a few degrees either way? could this throw out the channels that are currently working?

Yep, rotating it is skew. If you can get a signal strength meter or percentage to display on your STB, that is the best way of adjusting it - rotate to get the best reading.

You will only need to move it a few mm in each direction - slacken the adjusting screw just enough that you can move the LNB, but it is still held snugly, move it slightly and give it a few seconds to settle before deciding if it needs to be moved further.
