F3S sudden no signal problem

[middots3]

Hi all i have a V8S in my living room, a F3S in my bedroom and another F3S in a different bedroom.
The F3S in my room has all of a sudden started showing up "NO SIGNAL" on ALL channels. I haven't updated or anything.
I noticed this last night, then it suddenly went off and was working as normal all night, until i just turned it back on and "NO SIGNAL" again???

Both other boxes are working fine so it can't be a dish alignment problem. I'm a bit stumped? I haven't done any updates as of late and it has just happened completely out the blue.

Any ideas?

Sounds like a new LNB could be needed

disconnect the feeds from the other 2 boxes that are working (sat cables)

then reboot the box thats not working to see if you get the channels back
Have you got a feed (cable) to each box or are you using a spilter ?

I have a double LNB.
The box downstairs has the usual 2 cables going into the back of the V8S.
The double wires upstairs both go into my bedroom but i have split them and one veers off into another bedroom.

One going into the box that is showing no signal:

And 1 of the double wire going off into another room:

Do you think this method is causing problems? It's been working fine for about 6 months.
I've tried using other boxes with the wire in my room and still nothing. It will come on intermittently for a while then just go of again.

The box down stairs only needs one cable.......

Yes i have tried it, no luck.
It is all working fine again now though, maybe the rain the other night disrupted the signal? I'm stumped .
