Hey there!
I've finally gathered the courage to try and fix the wall-mounted TV stand after a friend sat on it, which caused the stand to come off the wall a bit.
Today, when I unscrewed the stand, the wall looks like this at one of the stand's four brackets:
The plug has come out and ripped material around the plug hole.
The wall is very porous and presumably lightweight concrete?
So the question is, how do I fix this? Can I fill the hole with something and drill a new hole in the same spot?
That would be the best since space is tight and it's difficult to move the stand on the wall.
Raising the stand a few centimeters and drilling four new holes might be an alternative.
