Wiring question

We have bundled service (cable / Internet / Phone) with Spectrum.  Dallas suburbs (75077)

Two set-top boxes and a cable modem.  Even though we have phone service, we don't actually have a phone plugged in.

 

The modem and one set-top box are connected directly to wall outlets via a direct coaxial cable.

 

the other set-top box is connected to a splitter (see image below).  Then the splitter is connected to the wall outlet and the other port is connected to an AC Adapter that is plugged into an electrial outlet (see 2nd image). 

 

We wanted to move the TV in that room and stop using the cable box (go to Roku).  That work was done and everything worked fine.

 

However, when I went to remove the AC Adapter and the coaxial wall outlet, that resulted in the entire house losing all service.  We tried to replicate the configuration at the other set-top box but that dind't work.  So right now we have AC Adpter directly into the coxaxial wall out (last image). 

 

How do move or elimate this wiring?IMG_0078.jpeg

Re: Wiring question

Looks like a power inserter for an amp somewhere in your wiring. If you are no longer using cable boxes and such, may no longer need the amp.

May be best to have a tech re-evaluate your wiring. If the coax jacks are indeed no longer needed, all those splits can be taken out of the equation, possibly reclaiming signal strength/quality to the point the drop amp is no longer needed.

Re: Wiring question

We still have one cable box and the modem - so the jacks are still needed.

 

Can the power inserter be placed in an active jack or would it typically be tied to just this spot?

Re: Wiring question

If you need to have the power supply plugged in to get signals to your connected devices, there is another amplified splitter hiding somewhere in your home that connects to of the all active outlets.  That amplifier unIt and the power supply should be removed and replaced by a single 2-way splitter that looks a lot like the power inserter shown in your picture.  HINT: They are probably not connected to work correctly with Spectrum's telephone service.

There must be some power consumer in your wiring that is needed for everything to work.  If you lose ALL service when you disconnect, I'd imagine it doesn't matter which coax jack in your home you use for power insertion.

 

Can you not connect this power inserter at the "other" set-top box?

Tried that the other night to no avai (but it was an attempt to replicate the connection with the splitter and the cable box).  Will try again tomorrow with the "simple" setup of just the power adapeter straight to the outlet.

Re: Wiring question

You are going to need to figure out what piece of equipment is upstream of the cable outlet with the power adapter.  There could be another filter on the other side of that run preventing power from entering from the "other" side.

 

Do you have access to the "other" end of all your cable runs?  (i.e. - are they all home run to a media closet or common location?)

 

Where are all the splitters in your home?  Where is the grounding block?  Service termination point?
