The colours are fine, they show the correct cable is in use .

As BatBoy says re T3 and T4, but don't cut them, just gently lift out of the jaws of the terminals. Fine-nosed pliers are best. Just make sure they won't make contact with any terminals when you replace the faceplate.

Be careful not to disturb T2 and T5, they do all the work.

As I said, this is unlikely to deal with the timing problem, but it may. It will almost certainly benefit the connection in general though.

The plug-in extension cable is also probably a noise source as well I'm afraid. Those usually have T3 connected. Fixing that can be messy, see towards the end of this page.

What time does your central heating come on?
Do you have a Sky box, is it on a filter, has the box been replaced?
If you have a Sky box, what happens if you turn it off and disconnect it from power and the line when the problem is occurring??

The extension cable is just a temp thing anyway that I've been using for testing.
I had already considered the heating and ruled it out.
The Sky box didn't have a filter on originally, but it does now, however it was working fine without one. I hadn't noticed because I wasn't here when it was installed and I don't use it personally anyway.

I've ruled out the Sky box by disconnecting it from the phone socket, how would turning the actual box off make a difference?
I ask as 'its been programmed for all my stuff'.

I've already removed the wires and I'm currently set up with everything back to how it should be.

Personally, I can't see removing the wires as fixing the timing cut outs, but if I get a boost in performance from it, thats a result in itself, so thanks for that.
I'm basically just waiting now for the magic hour to arrive!

Does turning the Sky box power off lose the settings? I have no idea as have never had and will never have one.

The only problem with leaving the power on that occurs to me is any RF interference coming from the power supply. Sky Box unfiltered would have been screwing the broadband performance, even if it didn't disconnect it. Double filtering it can also help.

Good luck, we will be watching!

I really don't know what it would do if the power was cut, but the threats of violence I got when I suggested it where not to be ignored

The Sky box is in the lounge and is plugged into the phone socket behind the TV.
This has been unplugged during testing and the main testing I've done has been from the NTE in the hallway via the extension line. I can stick a second filter on it, but again we hit the whole timing aspect of this problem.

If removing the 2 wires fixes this problem I'll be amazed and even more confused than I am now.
One of my customers is BT so I'll be calling in a few favours tomorrow and see where that gets me.

Thanks for all your help though and 4 more hours to go

No - it doesn't.

Nor the (series?) recording sets?

From the sticker visible on the front of the NTE, yours is a fairly recent build house. The issue with this is that an electrician will have run in the extension wiring whilst fitting the electric cabling. For sure there will be little or no difference in the cables route, and it is most likely picking up some induction. As suggested elsewhere, unscrew every socket, and detach all terminated wires apart from those in 5 and 2 (should be white/blue and blue/white throughout). Then see how it fairs. Worst case scenario, buy a faceplate filter and use powerline adaptors to get t'internet where you want it.

No. In fact a power off/on is often the solution to stuttering and lip-sync problems.

Well no disconnects as yet and I would have expected at least one by now

In most houses there is usually a routine of the 9-5 variety so that could make it easier to create and then track down a time related problem like this.
However in this house everyone works all manner of weird hours and there is no routine at all.

Just to clarify, I've only removed T3 & T4 at the NTE.
I can do the rest of the sockets, but will wait to see how this goes.

Will update later, thanks again.

OK had the first one, hopefully it was just a one off glitch.

Is it possible that removing T3 & T4 at the NTE has helped it last this long and removing them at all the others would improve it further?

I kind of figured it would be like a ring circuit and terminating them at the NTE would break it?

Is it necessary to remove them from a socket that isn't being used as well?

TIA
