I think I should start with a hello since I'm new to the forums; while at the same time asking for opinions with an issue I've discovered during the installation of my new 37" Samsung series 5 HDTV...
I'm trying to mount the TV fairly high on the wall (which I think might be part of the issue) in my bedroom. So I worked out where I wanted it and marked up six holes for the wallmounting plate (following instructions in the manual). Drilling the lower three went without issue - solid brick which took a significant amount of force to drill but I ran into problems with the upper three.
The wall seems to be clinker (horrible powdery cement) filled at the top, rather than brick all the way up and as such all three of the upper holes are potentially weak. I think it's clinker as the dust is too dark to be breezeblock (that and the house was built long before breezeblock was 'an option'...) Honestly, I have significant doubts about their ability to hold the weight of the wallmount and TV using the provided mounting plugs and bolts. I would be less worried if it was the lower three holes that had this issue, as at least they wouldn't have most of the weight on them.
Now, shining a light in the cleaned upper holes shows what looks like a fairly solid material, and giving it a moderate poke with an awl didn't do much of anything. But after the three lower holes took quite some effort to drill, the top three we like drilling butter. It's how easy they were to drill that has me worried about their ability to hold 18KG of TV and 11KG of wallmounting hardware.
I'm trying to decide whether simply buying an alternative bolt system for the top three holes (such as something designed for breezeblock/clinkerblock) would be OK, or whether I should fill the holes in and write off the wallmounting kit as money wasted in the process of learning a lesson.
I can try to take pictures if needed.
Thinking about it, I can shift the wallmount down a bit, using the original 'lower' holes as the new 'upper' ones... but that will mean my plans for space beneath the TV will be scuppered. Still, it's really the only other option as drilling holes elsewhere will likely compromise the integrity of the wall against tensile and shear loading. Don't want the TV falling off and ripping a chunk of wall with it!
Thanks in advance to any who try to help.
