I'm not a wall mount guy. My 53" sits on a piece of furniture designed for Flat screens. For My $.02 Worth the TV should be at eye level without having to tilt my head back to view the screen.
How ever, not sure in your case if that is feasible for you. And alos, it's your TV and if you want to wall mount it then go for it. My problem is plugging all those "HDMI" cables in. In your case, I think the best bet is to get Help hanging it. Maybe calling the store where you bought it from and asking how much to hang the TV. Even if it was bought a while ago.
These Mfg's need to come up with a system using a Long cable which is connected to a break ou box with all the HDMI connections and goes back to the TV. Or a combination of either or.
I find that from time to time I need to get to a HDMI Connector on the rear. On my set up I can slide the TV stand out so I can plug or unplug devices. Good luck on your quest to Hang that monster.
