[Closed] TV remote is possessed!!

When I turn the volume up on my tv remote it keeps on going until it gets to the top I can hold it back by pressing down but eventually it'll go all the way the other way, it also does it with the direction buttons. Now I thought the TV was faulty but it's doing the same with my free sat box, both different remotes. Something is repeating the signal from my remotes several times what would cause this? Nothing's changed in my home.
