Nice setup but this.

It's going to be harder to break her of these habits now because they're so ingrained, but I don't think it's totally impossible, but it will take a lot of work.

When you catch her scratching something she shouldn't be, pick her up, bring her to the nearest scratching post, and move her paws on it in a scratching motion. She might have no idea what they're actually for, thus her continued indifference toward them. There are different coverings for the posts too, so it might help to try a few different ones and see if she prefers a carpet/rope/other fiber covering.

If she has certain places on the furniture that she scratches, you can try getting some of those scratching posts that hang off doors or drape over the arm of the couch and try to place them strategically. You might have to get creative, but it will also help teach her what surfaces are and are not appropriate to scratch.

Part of the problem might be too much energy that she can't burn off. If you're having trouble getting her to play, that means she's not getting enough exercise and she has to express that energy somehow. It's the same with dogs who chew on everything...often exercise helps a lot. Does she respond to a laser pointer? Is there a difference in her attention when you drag a string across the floor vs dangle it in the air? It took me a little while to figure out how to play with my cat because she's not good at following things in the air and she also seems to have little interest in conventional cat toys. Her favorite toy is an old sweatshirt pull. She doesn't seem interested with anything more elaborate...stuff on the end of a string doesn't interest her, she just wants the string. You might even have success by dragging a piece of old wire around in front of her (though I'm not sure if that would encourage her to go after cables more or not). If she'll tolerate it, try getting her in a harness and letting her explore outside on a leash. You don't need to train her to walk with you, but you can hold on to her while she pokes around.

I think in most office supply stores you can get plastic tubing specifically for cables. It might be worth it to get a bunch of this stuff and cover as much cabling that she is able to get to as you can.

You could possibly try softclaws, but I've always been hesitant after reading some concerning reviews about them not falling off when they should and having the nails grow around into the pad of the paw. If you do try them, keep a very close eye on your cat. Don't declaw her. Cats come with claws. If you want to have a cat, claws are things you need to be prepared to deal with.

If all else fails, you can always consult a cat behavioral professional. If nothing at all helps, you might have to come to terms with the fact that perhaps your particular situation isn't appropriate for your cat. Some cats need more space, need more social interaction and need more attention. I hope you are able to work things out!

Hot Glue might have been a better choice, as they could have been melted off cleanly. Or even better? Grab a Wire Tube and throw wires into it, then drill square in wall and feed through to bottom. (Or run down back of tv mount). Problem solved.
