Hi, I've just gone out and bought myself a 14mm drill bit and M8 rawlbolts to mount my new plasma (37PWD7). Now, I admit I know next to nothing about this, so please bear with me... When I bang on the wall, it seems very solid. The house is very old (likely over 100 years). I drilled a small hole in the wall with a 3mm drill to test and found that the drill went in very quickly for almost an inch (like butter) and then I hit some hard stuff that only required a small amount of effort to get through. When I pulled it out there was a light brown/caramel powder on the drill bit. The wall is smooth and obviously has some sort of plaster covering it (seems almost like paper). This is a rented property so I dont want to do too much damage.. just cover the holes in and repaint wall at end... Am I wasting my time? Should I just pack this project in and go buy a stand? Any advice would be greatly appreciated as looking at my plasma in its box is making me mad!! Cheers, Nick.
