Problem - solution (Hdmi cable / ethernet) wall

[Magic_x_uk]

Hi

Years ago. I had the electrician put me some sockets in for the TV, chased out, ran 3 HDMI cables up the wall. All plastered & decorated over.
Tv then mounted (days before tv's needed ethernet.

Anyhow, new tv. Obviously has ethernet (does have wifi) (LG Nanocell)

Cannot add a ethernet cable otherwise have to dig into walls etc.

Would I survive with WiFi (as firestick, sky all feeds into AV amp) it would only be the tv

Or can I utilise one of the spare HDMI cables to use ethernet if I was to hack it to pieces and fit RJ45 onto each end?

Not sure. Hence asking

Thanks and hope this drivel makes sense.

Since HDMI cables typically have 4 x twisted pairs carrying the HDMI signal, I'd say you could strip the end off and if the wire guage is too large for an RJ45 plug, just get a keystone RJ45 socket which will fit pretty much anything..

Over short runs you'd be surprised what you can get away with!

Go for it.

Did you electrician not bury any trunking? I put a load of 3 section ducting/trunking between deep dual gang backboxes to allow cables to be pulled through.. but I've seen some just effectively place plastic covering over the cables and plaster on top, making it impossible to run anything new..

Unfortunately the cables were in trunking, tight and covered then plastered, I thought that would be a option. But no chance. There in the wall for life. Thanks for the helpful idea.
