Not really a disaster but not sure where else to post. I have removed a tv bracket fixed to a hollow wall with metal wall anchors. When I removed one screw it was very loose and felt like it wasn’t held in place like it should be. The anchor is also starting to come out of the wall. I want to remove it completely, causing the least damage because I would like to replace it like for like. I have looked online on how to remove them - suggestion is to screw a screw in, bang with a hammer to close up the anchors. However, I can’t screw the screw back in to do that. Any other ideas?
