Keep in mind your connections on the back of the set. If they are horizontal, meaning straight out from the back of the set, you might have issues, unless you get some right angle connectors. Also, the power cord on the set too, those sometimes plug in horizontal and not vertical.
Also, the set being that close to the wall, there might be overheating issues with the vents in the back of the set.
