Ongoing communal issue

[TessleP82]

Hi, I live in a small block of flats. Myself and a neighbour have break up on some channels most days on our Sky Q boxes.

A local company have been trying to get to the cause of the problem (they didn't install the original system).

When my neighbour or I got Sky Q the Sky man used one of their 'adaptors' as the system is the 'old' V5 equipment.

This has been changed for a DSCR switch, the signal has been attenuated, the LNB changed and a new PSU and DC blocks installed but we are still having the same problem. 

No-one is sure where to turn next. I don't blame the local company for not fixing it as it seems its an old fault?

Does anyone have any ideas what I can suggest to them?:

Thanks

Our communal system expert is @Godfrey so I've tagged him in with the hope he can offer some help or advice.,

@TessleP82  A suitably qualified communal Integrated Reception System (IRS) installation engineer would initially check the signal levels and Modulation Error Ratio (MER) quality of everyone of the transponder signals that emerge from the LNB.

Then they would check these parameters on the 'Trunk' distribution cables that serve the central distribution cabinets on each floor, then the transponder signals that emerge from the multiswitches in each central distribution cabinet, and finally at the point where these signals emerge from the wall mounted media plate in your flat.

This is an illustration of a typical test meter scan of all the required transponder signals in order to confirm the signal levels and the requirement that the Modulation Error Ratio quality of each transponder is at least achieving a MER ratio in excess of 11 dB.

If your local company cannot do this type of basic test procedure, then you will require to employ a suitably qualified communal IRS  'System' engineer who can analyse exactly what component is faulty instead of throwing away everything in sight!

The Confederation of Aerial Industries has a website, with Sky listed as a supporting associate company, where you can search for a suitable 'System' engineer who covers your locality.
