This is wrong in so many ways!!

NOTHING should ever connect before the filter

That filter needs to go DIRECTLY into that master. Then the sky box needs to connect to the filter.

At the moment the sky box is unfiltered & whatever connects to that white cable coming from the boubler is unfiltered.

If you don't need whatever that white cables going to I would....

Connect the filter straight into the master. In the ADSL side connect the broadband

In the phone side connect your phone and sky with one of these

I don't think you will benefit what-so-ever from a prefiltered faceplate as you do not have any extensions coming from the faceplate.

So it will work nicely IF that filter goes straight into the master.

Anything connected to the phone line needs to go into the phone side of the filter.

You can get 3 and even 4 strips for the phone. Just get something that'll fit into the filter.

Looks like my Sky installation is causing the problems then, this is how they left it.

The white wire into the bottom of the doubler is a Sky wire coming in from outside. The doubler won't come off the faceplate, I don't want to force it in case it breaks. I thought that taking the black wire out of the doubler would mean Sky doesn't work but it works ok from what I can see. (It goes into a socket marked telephone line in the back of the sky box)

Phone, adsl & Sky all work ok when the filter is plugged into the BT test socket.

Any ideas??

It seems odd that the doubler will not come out. However, what happens if you just detach the black cable to the Sky box?

If that fixes things, and you still can't remove that doubler from the master, then get another doubler and plug that into the Phone socket of the filter, with the phone and Sky lead into that.

Have they only just installed the Sky doubler?

In reply to a post by Wilsanio:

The wires I have available are orange and white, the other blue and white cables seem to be connected to something already. Would appreciate some assistance as to how to resolve this.

Photo of the blue and white cables please.

Have you any extensions in the house even if you don't use them? If so, do they work?

There is usually a small catch on the side of doublers that has to be squeezed to release it.

A Sky box works perfectly well without a phone line, until you try and order some pay per view content. If in contract Sky will send a letter to remind you connect it, since now and then the box calls home with various bits of data.

Sky installed when I moved in over 2 years ago. No other extensions in the house. The doubler won't come out even when the lever is pressed. Shoud I contact Sky? I have ordered the XTE master faceplate also.

Mmm do you ever have a damp problem? Contacts might have got a little damp and stuck together through corrosion.

Sky will probably charge their usual call-out fee, or arrange an Openreach engineer which again will cost.

Given a stuck double the faceplate seems a reasonable move.
