Hi all, I am thinking of wall mounting my TV but have a small problem. The wall it needs to go on is about to be wallpapered by a decorator. In my previous house to hide cables I essentially made two holes in the wall which had brush plates on them and were largely hidden by TV and furniture. However, that was on a painted wall which could be touched up. Is it a terrible idea to try and do this on a wall which has been wallpapered? The TV mounting aspect probably has to be done afterwards but it is the cable channelling that worries me. Don’t know why I didn’t think of this problem beforehand and I am now in massive trouble with my wife.....to the point that I am tempted to instead make a wooden addon shelf onto the cheap Ikea unit to rest the TV on instead.
