Repairing Damaged HDMI Plug on Cable Plastered in Wall: Projector Installation Issues

Hello, I have a Mega problem. I bought a flat with installation for projector. Everything would be ok were it not for the fact that the HDMI cable plastered in the wall and ceiling at the exit from the ceiling at the projector has a damaged plug. The connector housing and pins inside are loosely skewed so that I cannot connect under the projector. Is anyone here who has repaired this problem? Anyone solder a new cable plug? From what I read it is not so simple ... please help. Regards

It would be best to buy an HDMI plug with a PCB that makes soldering easier. Something like that:


You will find Allegro ("HDMI PCB plug") for a few PLN.

Ok, let's say that I could start soldering to this hdmi pcb plug, but how can I grasp which cable to which soldering pin?

As you wrote "the HDMI cable at the exit from the ceiling near the projector has a damaged plug. Loosely the plug housing and pins inside are bent" then you have a good situation at the entrance.

We assume that the existing cable was good in its time and someone broke / used it. You will need to disconnect each wire from the old plug's pin and then connect it to the corresponding pin of the new plug. You can't swap the cables, you have to plug them all in as they were in the old plug. Nothing easier.

Plan A:
1. You are gutting this damaged plug.
2. You make and print a color photo of how the cables are connected with the plug pins, or draw and describe what you would picture.
3. If the cable is long enough, then cut off the plug.
4. You isolate the wires.
5. You solder according to your description.
6. You mount the plug housing.

Plan B:
1. You disassemble the cable-pin and solder the cable-pin and so cable by cable and pin by pin. You won't go wrong with cables even if you are color-blind.

It may happen that an existing cable does not work and never works. For example, the right number of wires is missing, or in this plastered wall someone lengthened this unfortunate cable and swapped the wires at this connection in the wall. Then you will have to move your head. However, it will lead you to more or less the same effect, you will enrich your knowledge in the subject of cable medicine.
Without 'seeing' the wires in your cable, you can not pathologically advise which wire to which pin to connect, so that the cable works well. Nevertheless, I recommend such sites:
https://www.lammertbies.nl/comm/cable/HDMI.html - colors of HDMI cables, functional marking of pins;
http://pinouts.ru/Video/hdmi_pinout.shtml - site with various plugs and sockets;
https://en.wikipedia.org/wiki/HDMI - HDMI connection standard in English;
https://pl.wikipedia.org/wiki/HDMI - HDMI connection standard in Polish.

Now your step. Good luck

The cable certainly worked because friends who previously lived in this apartment used this cable and it worked flawlessly so the problem is only the damaged plug (which I suspect had to get damaged but smaller with it). I like the plan And I will have to try to use it, the only problem for me is that the cable protrudes from the ceiling about 25cm and it is uncomfortable to do something about it and, I'm afraid that I would damage or tear the cables from the pins when removing the plug housing. Well, keep your fingers crossed, thanks a lot for your help

Hello again, does anyone know what this connector from the YT movie is called? Where can I buy such a thing? It would be a lot easier for me to fix this cable with something like that.

My mistake, just look at the comments below the movie. If it was useful to someone, I meant the HDMI Terminal.

Who will exchange the HDMI input for me?
The dog bit my tip at the set-top box the child finished the job and the cable in the wall ?
Option 1 pull a new cable, option 2 replace the end. Do any of you live near Krakow - Bochnia and would he fix it for me?
I am begging you
