Skyq not working

[odysseus+2020]

My communal cabinet is 3 metres high on my neighbours wall.

I borrowed a ladder and i hope these pictures will provide a answer.

@odysseus+2020Whilst the photos are waiting approval before they can be viewed if there is a problem with a communal dish/distribution it is up to the "management agent" not Sky to sort it out.

@bob1234 Hi Bob im stuck between Sky and the contractor who doesnt believe Skyq

needs a separate power source.Im hoping some one can pinpoint any additional knowledge

to help my cause.

I dont want to cancel my subscription but its looking more likely,I cant afford to keep paying

for something I no longer receive,thankyou for the reply.

@odysseus+2020unfortunately I know next to nothing about communal distribution systems if @Godfrey is about, I am sure he will be able to give the information you need.

@odysseus+2020 

The equipment in your images confirms that your communal management have installed a Triax TDSCR504 dSCR multiswitch to support residents that want a feed suitable for a Sky Q receiver.

Two of the output ports, ( 1 & 2 ), appear to be unused and are both terminated with a 75 ohm dummy load, leaving output ports  3 & 4 connected to residents flats and capable of supporting Sky Q receivers.

Alas, no attempt has been made to supply a local 20v supply of power into this Triax TDSCR504 dSCR multiswitch.

Without a much more detailed analysis of how this device is presently receiving its power it is difficult to decide if the two 'DC blocks' inserted in series with the 'Trunk' feeds will mean that it is not receiving any power from the communal Integrated Reception System (IRS) and it will be relying on taking the power that it requires from any satellite receiver connected to its output ports.

Without measuring what current is actually being drawn from any Sky Q receiver connected to either output port 3 or 4 I can only guess that there is a distinct possibility that a method of supporting the limited power supply capability of Sky Q receivers will require to be adopted in each residents flat.

Output port 3 has a coaxial cable that appears to be terminated by a screw on 'F' type connector, and Output port 4 has a coaxial cable that appears to be terminated by a compression 'F' type connector, suggesting that two different residents are presently connected to this dSCR multiswitch by just one coaxial cable.

This would limit the available options to remotely power this device from individual residents flats to using 'Power Inserters', if the dSCR was not being powered from the 'Trunk' distribution cables.

At the end of the day, this dSCR multiswitch requires to be powered, and if this power is going to be extracted from a Sky Q receiver, apart from possibly a Sky Q V3 device which claims to be able to supply double the current that the previous Sky Q receiver designs could provide, then individual residents will require their Sky Q receivers to be supported by having 'Power Inserters' provided in each flat where a Q receiver has been installed.

It is not always immediately obvious when a new Sky Q receiver installation will initially work fine for a short period of time, and then start to have problems attempting to continuously supply power to a dSCR multiswitch, because initially with just one Single Cable Router (SCR) 'User Band' instructed to be powered the current from a nominal 11v source will be around 170 mA, as more 'User Bands' are requested to turn on to provide additional feeds for its tuners, this can quickly rise to around 220 mA if 10 'User Bands' have been instructed to power up.  This often explains why some subscribers inform us that their overloaded Sky Q receivers often work for another limited period of time whenever they have been powered down and the load on their Sky Q receiver is temporarily reduced to supporting a relatively few 'User Bands'.

Instead of attempting to convince either Sky or your contractor to provide you with a 'Power Inserter' you might like to consider the purchase of a 'SP161 Power Inserter' from ebay, if this is then inserted between your Sky Q receiver and the satellite socket on your wall mounted IRS media plate, it might well be able to supply enough energy to the unpowered dSCR multiswitch that is feeding your flat from the communal distribution cabinet.

@Godfrey,thankyou for your suggestion,could you tell me how it is different from the sky plug 

I have now.As you noted other residents are by passing communal system with their dishes

which i was told by Sky was illegal and im sure one or two have been connecting their equipmemt

sneakily.At least you have given me something positive to think about.

I have looked on ebay and have seen SP161 but would still like to know how they are different.

Thankyou

@Godfrey, sorry I have just taken my connection offmy wall and it's a 

SP161, does that mean I'm back to square 1.

Well, at least that explains how the Sky MDU trained engineer, who initially installed your Sky Q receiver, resolved the problem of powering that dSCR multiswitch which is feeding a Sky Q compatible SCR signal to your flat.

Are any of your neighbours having similar problems with their communal IRS satellite transponder signals?

@odysseus+2020are there any lights on the SP161

[odysseus+2020]

@bob1234 Hi Bob,yes the centre light Sky is always on.Sometimes the Eco light is on

but never the fault light.Thanks for your reply.

[odysseus+2020]

@Godfrey ,Hi my neighbours dont have any problems with their dishes normally.

Extreme weather is the only worry.Thankyou for hanging in here and trying to resolve my problem.

The dSCR multiswitch will only be receiving power from the SP161 Power Inserter whilst the ON led is illuminated, it will not be supplying any power to the dSCR multiswitch whilst the ECO led is illuminated.

Thus your dSCR multiswitch will only be able to supply the required SCR 'User Bands' whilst the ON led is illuminated.

The ECO led should only be illuminated during the overnight (around 02:30 - 06:00) ECO period if your Sky Q receiver has been configured to use the ECO power setting.

But, does any neighbour who is using the communal IRS installation report similar problems after 21:30 hrs?

@Godfrey  Hi,Im the only user to experience any problems,just to recap.

Everything   was working well till Tuesday 8th,when my power was

shut down due to having fuse box replaced.Then overtime my skyq wouldnt

work in the morning and then at about 21.30 no satellite signal appeared.

And now no tv at all.Settings say signal locked,signal strenghth 80

signal quality 90 LNB type SCR,no matter how many reboots nothing works

from black screen technical fault.no satellite signal,to blue screen there is a problem.

Very frustrating as i am a sports nut.Thanks to all for suggestions.
