For example she is obsessed with touching the TV (DH's precious TV ), no matter what we do she wont stop, she has already damaged it quite badly and has to stop before it ends in divorce proceedings as I am meant to be watching her 100% of the time and therefor all damage is my fault. She will start to touch it and we will tell her no, she just smiles at us and goes on to do it more. We try to physically remove her or take the object off her that she is attacking the tv with with. It just makes her worse, she becomes so determined to do it, it just ends up in tears. Yelling at her does the same thing and she gets upset at us for yelling.
My goodness, are you sure you're not living in my house??!!

My DP is exactly the same. And my DD used to do the same thing.
When you say 'we', does it make any difference if it's your DH who tells her off? Yelling does nothing in our household and I don't use it either.

I agree with the other girls on a lot of their points.

I tried an alternative technique to using the TV (since she was usually wanting to play with the buttons, etc, or wanted to make the Wiggles appear herself). From the 'gentle' POV I would ask her what she wanted or try to guess (she was usually frustrated that whatever it was wasn't happening) and if it was okay either try to give it to her or tell her, 'sorry, honey, we're not watching TV now [for whatever reason, with Lucy it can be as simple as 'the Wiggles have gone to bed now'], but why don't we go and do x, y and z?' Plenty of enthusiasm for the new task usually distracts a little. If that doesn't work I then physically remove her from the room and close the door. Commence tantrum, tantrum ignored, whimpering then gets some consolation and distraction.

Another thing that has helped her treat the TV better is that we have a small second TV in our bedroom with a video player hooked up to it (very old-fashioned, but harder to break!) and I borrow out videos from our local library. Lucy has learnt how to load them herself, push play and turn on the TV. Since it's all hands-on for her she loves using it and then sits herself down to watch the short video (I love the story ones). It keeps her occupied while I have a shower and has taught her how to use something that requires more care. Treating toys and other possessions nicely has been something I've put a lot of effort into lately (throw it, it goes away, put it on the floor, you must pick it up, stand on it, it goes away, etc, etc). So now a warning is all it takes.
